                          1 Heart Attack and You

  Did you know that, worldwide, twenty-three people each minute have a heart attack? This adds up to about 12 million heart attacks a year. More than 1 million Americans will have a heart attack each year, and 14 million Americans now living have had aheart attack or angina.¹ In fact, if you live in an industrialized country, heart disease is either the number one killer there or a major cause of death.
Even when heart disease does not kill, it maims, so if you have had a heart attack, youmay well find yourself attending a cardiac rehabilitation program to help...
 II The Participants’ Perspectives
January 17, 2000, began for me like any workday. I was up at 5:45 a.m., showered and had breakfast, was on the road by 7:50, and was in my office by 8:15.
I had booted up my laptop to check the weekend’s e-mails when I started to feel weird and queasy, though not nauseated. I also had an uncomfortable tingly sensation in my jaws and along the triceps in both arms. I realized something was wrong and decided to wait a few moments to see what would happen. And, in fact, after a couple of minutes the sensations eased off

3 Doing It My Way 
On February 21, 2000, I woke up at 6:00 a.m. feeling pressure at the center of my chest. I assumed the pressure would go away, so I went ahead with my daily routine—shower, coffee—after which I got ready for work.
As I drove to the office, the feeling of pressure in my chest increased, and I became more and more uncomfortable. I decided I needed to have it checked out; even though I was only 47, I began to wonder if I was having a heart attack.
I turned around and drove to the emergency room of the...
4 It Takes a Team
August 20, 1988—a date I will not forget. On that day I joined a new team. I did not plan to become a participant, and I did not know at the time that the team would become a focus of my life. As I look back, I recognize that the team has had various members and that my own participation ranged from the initial passivity of being worked on in a hospital emergency room to a highly active role in understanding and managing my chronic cardiovascular disease. Many people have been part of my team since that fateful day; some...
5 Reversing Angina
The evening of August 12, 1994, is one I will never forget.
We were on vacation in our summer cabin, which overlooked a magnificent unpolluted lake in the East, very close to the Canadian border. On the previous day, my 83-year-old husband, George, (I was then 75) had mused out loud how wonderful it was that we were in excellent health. And we were looking forward to celebrating the birthdays, on the twelfth, of our granddaughter and daughter-in-law.
On August 12 our son was driving his Volvo, which at the time had the highest safety rating of any car. He...
6 Preventive Medicine Works
Most people do not associate heart attacks with African Americans. But I am an African American, and my elder brother died of a heart attack at age 47; I developed angina when I was 60.
In fact, African Americans have more heart attacks and strokes than Caucasians. High blood pressure is four times more common, and diabetes twice as common. One result is that heart attacks are more common in African American women than in Caucasian women, and tend to occur at an earlier age. For similar reasons, stroke and sudden death are more common in African Americans than in...
7 Modern Cardiology, Cardiac Surgery, and My Angina
Today is the day after my eighty-eighth birthday. I am celebrating, among other things, the fact that I am fit and healthy. How did this happen? Well, I think there are two reasons. First, my body has become a kind of showcase for the latest medical devices. Second, for the past twenty-five years I have belonged to a cardiac rehabilitation program.
Both my grandmothers lived into their eighties. One grandfather was killed in a railroad accident; the other died of “consumption” in his late fifties. My father lived into his nineties, my mother into her eighties. Heart trouble is not.
8 Success without Angioplasty or Surgery
After my heart attack many years ago, I soon found that no one was telling me what lifestyle changes Imight have to make to keep from having another. These days, most cardiologists and other health professionals readily offer such advice, but that was not the case for me—and if you are in a similar situation, perhaps my experience can serve as a guide.
My heart problems began in January 1984, at age 51. I awoke one night with crushing pain behind my breast bone, which radiated up into my neck and jaws and later spread to both elbows and.
9 Miracles Can Happen with the Two Ds
What my cardiologist and I were looking at recently was as close to a miracle as most of us are likely to get.
We were comparing two coronary angiograms. The first showed that the openings of two veins used by the heart surgeons to bypass my blocked coronary arteries had actually narrowed by 90 percent. The second, taken five years after the first, showed that those radically narrowed openings were normal.
A miracle? Only apparently. This dramatic change occurred because I believe in two Ds: the danger of cardiac Denial, which can kill you, and the beneficial effects of Discipline,.
10 Young People Do Not Get Heart Attacks (WRONG!) 
Heart attacks are for old people . . . the chronologically challenged!! That is what I used to believe. So why did I get my first heart attack in 1966, when I was still a month away from my fortieth birthday? And why did my son get a massive, near-fatal heart attack at age 42? Why did my father die at age 60 of a heart attack, and why did my three brothers all die of heart problems? My mother too had heart disease. At age 51, she sought medical advice for a bruised leg and died suddenly of a.
11 Myth: You Are Lucky to Be a Woman
The idea that women do not get heart attacks is a myth. Women get as many heart attacks as men; they just get them a little later in life.
A second myth is that Asians rarely have heart attacks. I immigrated from an Asian country, where a number of close relatives had heart attacks despite the fact that they were on healthy Asian diets. Several relatives on my mother’s side have diabetes, and many have had heart attacks already, between the ages of 50 and 65—and some of my nieces and nephews have had heart attacks at even earlier.
12 Risk Factors from a Patient’s Perspective
My story is vitally important for two reasons.
The first is that I was massively at risk for a heart attack. I had seven of the risk factors: I have diabetes, I had a strong family history of heart attack, my blood pressure was high, I led a very sedentary life, I was overweight, I smoked heavily, and I am a type A person.
Second, I developed a blockage of the large artery in the neck that supplies the brain, leading, in my case, to amini stroke. (It is crucial to realize that heart attacks are due to rupture of.
III The Health Professionals’ Perspectives
13 The Complexities of Proper Nutrition
Nutrition—what you eat, and how what you eat becomesyou—is extraordinarily complex, and no one knows all the answers. What is clear is that no single diet works for everyone. Just as there are many components of good health, there are many different diets and each is appropriate for different people.
People with heart disease tend to ask similar questions about diet. Are there specific diets that are helpful to people with heart disease, including those with diabetes? Which diets will help to lose weight? What about the new medical foods, such as the Heartbar®? Are diets
14 Testing and Treatment
Coronary artery disease is the most common form of heart disease in the industrialized world, and it is what most people mean when they speak of “heart disease.”¹ Let us look at the anatomy of the heart, the symptoms of coronary artery disease, and the tests used to assess it, before discussing treatment.
The first component is the heart muscle, which performs the heart’s primary function—to pump oxygenated blood throughout the body.
The second component is the coronary arteries, which supply oxygen to the heart muscle. The heart, like any other muscle, requires a blood supply. Three major coronary.
15 An Introduction to Cardiac Rehabilitation Programs 
Cardiac rehabilitation in the United States has undergone an incredibly rich and energizing thirty years. In the late 1960s you could count on the fingers of one hand the number of cardiac rehabilitation programs in this country. But Gary Fry, an especially enthusiastic and visionary cardiologist at the Palo Alto Medical Foundation in California, knew instinctively that there had to be something better than building more and more coronary care units for victims of heart attacks. His vision, his passion, was to keep people out of coronary care units, out of hospitals, and to keep them well.
16 Cardiac Rehabilitation in Action
If you had a heart attack in the United States in the 1950s, you would have had to stay in the hospital for six to eight weeks and not move out of your bed. During the next six months, you would have been allowed very little physical activity.
If you had a heart attack in the 1960s, you would have been much more fortunate, because it was then that the first programs were developed in the United States to promote appropriate exercise as part of your recovery.
If you had your heart attack in the 1990s, though, you would have.

Healthy Foods

                                                                     Destroying Your Weight Loss          You know that all-too-famili... thumbnail 1 summary
                                                      

            Destroying Your Weight Loss

        You know that all-too-familiar feeling: The one when you desperately need a snack, so you pour a quick bowl of whole-grain cereal or grab a bag of pre-portioned pretzels. Smart, right? Ehhh. It might make you even more hungry, unfortch. "When you eat processed carbs (anything made with refined grains, flour, or wheat), your blood sugar rises quickly because there's little to no protein or fiber," says Akilesh Palanisamy, M.D., an integrative medicine physician and author of The Paleovedic Diet. What's worse: They could be sabotaging your weight loss goals, wreaking havoc all over your digestive system and making it virtually impossible to lower that number on the scale. So read on to learn more about the foods you thought were a wise choice—especially when you just need something other than kale—and what you can swap 'em out for instead.   
Quinoa Chips

  This new-to-the-scene snack food features all the buzzwords that make it sound like the ultimate healthy snack: It's a superfood! And gluten-free! There's protein and fiber! The problem: They're basically corn chips with a little quinoa thrown in, says Kelly Schmidt, R.D., a nutritionist and blogger at Paleo Infused Nutrition. And the quinoa itself has been so highly processed that it's lost the nutritional boost that made it healthy in the first place. Need proof? Just compare the stats of one cup of cooked quinoa (8g protein, 5g fiber) to one serving of quinoa chips (1g protein, less than 1g fiber)—and then listen to your stomach make noise because it's still going to be hungry.

The better choice: Beyond nuts and seeds, there are plenty of ways to get that crunchy texture. Choose super-portable whole fruit like an apple or pear, or go for freeze-dried fruit—it has a sweeter, crispy taste and way less sugar than dried fruit, says Schmidt. Bonus: They're not super perishable, so they can be the go-to snack in your purse for a few days.          
Microwaveable Popcorn


Nutritionists always say popcorn is a healthy snack, and it is, so long as it's made right. "The microwaveable kind has cancer-causing chemicals in them," explains Palanisamy. One is called PFOA, which the EPA says is likely a cancerous carcinogen that's found in the plastic of the bag. The other is in the butter flavor, and it's known as diactyl, an organic compound that's been linked with breathing issues and lung disease, thus making "popcorn lung" a real—and serious—health concern.

The better choice: Still go for the fiber-filled popcorn, just DIY it on the stove (using heart-healthy olive oil) with an air popper like this one from Cuisinart. And don't be afraid to play with flavors, as adding in spices like turmeric or cinnamon can kickstart your metabolismwithout adding calories.
Fat-Free Cheese or Greek Yogurt

The obsession with low- and no-fat products we had in the '90sstill lingers, but reaching for them isn't better than grabbing the full-fat kind. Researchers found that people who ate full-fat dairy tend to have lower body weight, less weight gain, and a lower risk of obesity compared to those who continued the fad. They think it's likely because when you remove fat from dairy, you also strip away beneficial fatty acids that can help you feel full, so you end up eating more in the long run. Plus, a lot of people opt for flavored yogurt, which has tons of sugar that, once again, put your blood sugar on a crazy roller coaster ride.

The better choice: Go full-fat—and don't feel one stitch of guilt about it. As for flavor, mixing in natural foods like fruit, honey, or coconut chips can take your spoonful in whichever direction you crave.
Pretzels

These salty bites may sound like a smart snack since they're lower in fat and calories than potato chips, but they actually won't do your waistline any favors. "They don't contain any nutrients," says Palanisamy. "They're basically all carbs and loaded with sodium," so they'll put your blood sugar on a roller coaster ride, spiking your levels sky-high only to make you hungry as soon as it drops back down.

The better choice: Coconut chips, says Schmidt. Never heard of 'em? Get acquainted, as these babies are filled with healthy fatsto keep you full. And while they're typically sweet, savory lovers can get in on the action now as brands like Dang Foodsoffer up flavors like bacon or chili lime.
Vegetable Chips


Chips made with sweet potato, beets, or parsnip—those ought to be healthy, what with vegetables being the primary ingredient and all. But Palanisamy says they're pretty high in fat—around 9g per serving—and it's not the good kind. The oils used range from canola to sunflower or safflower, all of which contain omega-6 fatty acids, which promote inflammation that's been linked with autoimmune diseases, heart disease, cancer, insulin resistance, and weight gain. Plus, the whole reason you're eating them—because you want those good-for-you nutrients from the veggies—is a farce. Palanisamy says the chips have been stripped of those benefits, and they provide no protein and little-to-no fiber.

The better choice: If you're craving the crunch, go for a handful of nuts (almond or macadamia) or seeds (sunflower or pumpkin) instead, says Palanisamy. Yes, they're high in fat, but it's the healthy omega-3 kind associated with heart health, lower risk of cancer, lower blood pressure, andreduced inflammation.

              Cinnamon and Diabetes


 Cinnamon is not only a spice packed with healthful antioxidants. It can also be used to help diabetics control their blood glucose levels. While it should not completely replace other treatments, consult your physician about adding to your treatment regimen.
 
                                                                                                                                         
1
Use cinnamon to replace sugar. Because cinnamon is so flavorful, it can often replace small amounts of sugar in stove-top recipes, sauces, meat, and vegetable dishes. Replacing a sweetener with this spice can help reduce the amount of sugar you consume and improve your blood glucose levels.
  • Cinnamon is considered safe when used in the amounts normally found as foods-- this works out to roughly ½ to 1 teaspoon or about 1000 mg per day.
2
Add cinnamon to your breakfast. For instance, stir cinnamon and a small amount of agave nectar into oatmeal in the morning, adding berries and nuts to make it an even more nutritious breakfast. Or top off buttered whole grain toast with a dash of cinnamon and a sprinkle of a crystallized sweetener like Stevia or Splenda.
  • Cinnamon also goes well with peanut butter or sugar-free jam on toast.
3
Use cinnamon in meat sauces. Cinnamon pairs well with poultry, pork, and beef spice rubs as well as Asian-themed dishes, marinades, and salad dressings. Mixing to taste, replace some of the sugar or brown sugar with cinnamon for homemade barbecue sauces, pulled pork marinade, berry compotes, and even marinara sauces.

4
Replace sugar in vegetable dishes. Use cinnamon in place of brown sugar or regular sugar in candied vegetable dishes, such as candied yams, baby carrots, or sweet stir fry. Cinnamon lends a complex, sweet flavor without the spike in glucose.

5
Use cinnamon in baking. Baking is perhaps the easiest way to incorporate more cinnamon into your diet. If you enjoy homemade breads, muffins, breakfast bars, cookies, or pies, cinnamon can be easily added to virtually any recipe you love.
  • Stir cinnamon into baked good recipes. Extra cinnamon mixes best with dry flour, and you should mix thoroughly to prevent clumping. If a recipe already calls for some cinnamon, try doubling the amount or reducing the amount of a spice like nutmeg to replace it with cinnamon.
  • Use cinnamon to dust baked goods. If cinnamon has already been incorporated into a baked good recipe, try using a baker’s brush or sifter to lightly dust the top of the muffin, cake, or bread with cinnamon while it is still warm from the oven.
6
Add cinnamon to sweet and savory canning recipes. Canning fruits and vegetables offers an easy way to sneak cinnamon into snacks and sides that otherwise would be free of cinnamon. When used appropriately, cinnamon can make an excellent addition to sweet and savory canning recipes.
Use cinnamon heavily in recipes like apple or pumpkin butter, canned apples, and applesauce.
Add a 1/4 teaspoon of cinnamon to each large Mason jar of other fruits, like canned peaches or strawberries.
If you are canning or pickling savory foods, consider adding cinnamon with cucumbers, green beans, onions, beets, and even bell peppers
7
Use cinnamon in drinks. Try adding a little cinnamon to your coffee grounds in the morning to get a cinnamon-flavored cup of caffeine, or mix it into smoothies, diet shakes, and dairy-based blended drinks to get an extra dose of cinnamon in your day.

Adding a Cinnamon Supplement to Your Treatment Regimen

1
Consider taking a cinnamon supplement. If you don't want to add cinnamon to your meals, you can still add it to your diet by taking a supplement. Many health supplement and natural food stores sell cinnamon supplements at affordable prices.

2
Talk to your health professional about adding a cinnamon supplement. While a low-dose cinnamon supplement is unlikely to harm you, your medical advisor may be aware of potential interaction effects with your medications that would make it risky to take cinnamon regularly. It can interact with your diabetes medications, as both the cinnamon and the hypoglycemics work to lower your blood sugar and it is important to be certain that your blood glucose levels drop too low.
Keep track of how much cinnamon you are taking and keep track of your blood sugar levels using a home glucose monitor-- you will soon be able to determine how much cinnamon you need to help control your blood sugar.
3
Consider a supplement of 500mg of cinnamon per day. 500 mg of cinnamon taken twice a day has been shown to improve A1c levels (and the levels of blood fats). A1c is used to determine average glucose levels for the previous 3 months, thus lowered A1c levels reflect improved diabetic control.[1]

Understanding Why Cinnamon Helps with Diabetes



1
Learn about diabetes. Diabetes is a group of chronic hormonal disorders that results in too much sugar (glucose) in the blood. There are a number of forms of diabetes. Type 1 diabetes is an autoimmune disorder, usually appearing when a person is quite young. Type 2 diabetes is an acquired disorder that used to be considered an adult condition that is unfortunately appearing more and more often in children. Type 2 diabetes is the most common form of diabetes. A third form of diabetes is called gestational diabetes and occurs in the second half of pregnancy and is relatively common, occurring in less than 10% of pregnant women.
Some physicians include pre-diabetes as an early form of diabetes. Individuals with prediabetes have higher than normal levels of blood glucose, but not high enough to be diagnosed as diabetics. Individuals with pre-diabetes (also known as insulin resistance) have a very high risk of developing type 2 diabetes.
2
Investigate how insulin affects blood sugar. Insulin, a hormone produced by the pancreas, is the main chemical messenger that “tells” the cells that it is time to take up glucose. Insulin is involved in messaging the liver to take up glucose and transform it into the storage form of glucose known as glycogen. Insulin is also involved in a wide range of other functions like protein and fat metabolism.
All diabetics can also be said to have insulin resistance. The reason they have high blood glucose is that the cells in their body do not take up glucose. The reason for this is that the cells in their body do not respond normally to insulin.
If the cells become insulin resistant, they “ignore” or can’t respond to the signal from insulin.[2] This can increase the levels of glucose in the blood. When this happens the pancreas responds by producing even more insulin in an attempt to “force” the glucose into the cells. The problem is that since the insulin has no effect on the insulin-resistant cells, the blood glucose levels can keep rising. The body’s response is to convert the high levels of glucose in the blood into fat, and that can set up a scenario of chronic inflammation and other disorders like full blown Type 2 diabetes, metabolic syndrome and heart disease.

3
Understand how Type 2 diabetes functions and its traditional treatment. The most common symptoms of Type 2 diabetes include: increased thirst along with more frequent urination, increased appetite, weight gain or unexpected weight loss, blurry or changed vision, fatigue, and increased number of infections.[3] Type 2 diabetes is diagnosed by your symptoms and a number of specific blood tests that measure how well your body handles sugars.
Most cases of diabetes can be controlled with a combination of medications (hypoglycemics -- medicines that lower blood sugars), diet, and exercise. Insulin may be ordered for some patients, especially those with Type 1 diabetes.
4
Find out why cinnamon can help control Type 2 diabetes. Current research indicates that one of the components of cinnamon, methylhydroxychalcone polymer or MHCP, can improve how cells respond to insulin. MHCP seems to mimic some of insulin’s activity. It also appears to work side by side with insulin, by improving the effectiveness of insulin. MHCP also has antioxidant effects, though it is not clear that these have anything to do with the ability of cinnamon to control blood glucose

                                                       Diabetes Introduction


















Introduction

Diabetes is a chronic (long term) condition marked by abnormally high levels of sugar (glucose) in the blood. People with diabetes either do not produce enough insulin, a hormone that is needed to convert sugar, starches, and other food into energy needed for daily life, or cannot use the insulin that their bodies produce. As a result, glucose builds up in the bloodstream. If left untreated, diabetes can lead to blindness, kidney disease, nerve disease, heart disease, and stroke.
According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), diabetes affects 25.8 million Americans.
While an estimated 18.8 million have been diagnosed with diabetes (both type 1 and type 2), unfortunately, 7 million people (or nearly one third) are unaware that they have type 2 diabetes.
Diabetes is widely recognized as one of the leading causes of death and disability in the United States. The Centers for Disease Control and Prevention (CDC) recognize diabetes as the 7th leading cause of death in the U.S.
There are 2 major types of diabetes:
  • Type 1. Also known as juvenile or insulin dependent diabetes, type 1 diabetes occurs when the cells of the pancreas that are responsible for producing insulin are destroyed by the immune system. As a result, the pancreas permanently loses its ability to produce enough insulin to regulate blood sugar levels appropriately. Type 1 diabetes is usually diagnosed in childhood, and while it can be managed, it cannot be cured.
  • Type 2. This form of the disease makes up 90% or more of all cases of diabetes. It usually develops in adulthood. It occurs when the pancreas cannot make enough insulin to keep blood glucose levels normal and is made worse by poor food choices, a sedentary lifestyle, and being overweight. Diabetes is a serious condition, but many people with type 2 diabetes do not know they have it. Type 2 diabetes is becoming more common due to the growing number of older Americans, increasing obesity, and failure to exercise. Type 2 diabetes can be improved, and in some cases even reversed, by lifestyle changes, such as adopting a healthy diet, becoming more active, and losing excess weight.
Pre-diabetes occurs in those individuals with blood glucose levels that are higher than normal but not high enough for a diabetes diagnosis. This condition raises the risk of developing type 2 diabetes, stroke, and heart disease. In fact, people with diabetes are 2 to 4 times more likely than non-diabetic people to develop heart disease. Pre-diabetes is also called impaired fasting glucose (IFG), impaired glucose tolerance (IGT), or insulin resistance. Some people have both IFG and IGT. In IFG, glucose levels are a little high several hours after a person eats. In IGT, glucose levels are a little higher than normal right after eating. Pre-diabetes is becoming more common in the U.S., according to estimates provided by the U.S. Department of Health and Human Services (DHHS). Many individuals with pre-diabetes go on to develop type 2 diabetes within 10 years.
Gestational diabetes is high blood glucose that develops at any time during pregnancy in a woman who does not have diabetes. Four percent of all pregnant women develop gestational diabetes. Although it usually disappears after delivery, the mother is at increased risk of developing type 2 diabetes later in life.
Diabetes may also be associated with genetic syndromes, surgery, drugs, malnutrition, infections, and other illnesses.

Signs and Symptoms

Type 1: Type 1 diabetes can occur at any age, but usually starts in people younger than 30. Symptoms are usually severe and occur rapidly. They include:
  • Increased thirst
  • Increased urination
  • Weight loss despite increased appetite
  • Nausea
  • Vomiting
  • Abdominal pain
  • Fatigue
  • Absence of menstruation
Type 2: People with type 2 diabetes often have no symptoms, and their condition is detected only when a routine exam reveals high levels of glucose in their blood. Occasionally, however, a person with type 2 diabetes may experience symptoms listed below, which tend to appear slowly over time:
  • Numbness or burning sensation of the feet, ankles, and legs
  • Blurred or poor vision
  • Impotence
  • Fatigue
  • Poor wound healing
In some cases, symptoms may mimic type 1 diabetes and appear more abruptly, such as:
  • Excessive urination and thirst
  • Yeast infections
  • Whole body itching
  • Coma. In severe cases, high blood glucose may affect water distribution in brain cells, causing a state of deep unconsciousness, or coma.

Causes

Both type 1 and type 2 diabetes are caused by the absence, insufficient production, or lack of response by cells in the body to the hormone insulin. Insulin is a key regulator of the body's metabolism. After meals, food is digested in the stomach and intestines. Sugar (glucose) molecules are absorbed directly into the bloodstream, and blood glucose levels rise. Under normal circumstances, the rise in blood glucose levels signals specific cells in the pancreas, called beta cells, to secrete insulin into the bloodstream. Insulin, in turn, enables glucose to enter cells in the body that may be burned for energy or stored for future use.
In type 1 diabetes, the beta cells of the pancreas produce little or no insulin, the hormone that allows glucose to enter body cells. Once glucose enters a cell, it is used as fuel. Without adequate insulin, glucose builds up in the bloodstream instead of going into the cells. The body is unable to use this glucose for energy despite high levels in the bloodstream, leading to increased hunger.
In addition, the high levels of glucose in the blood cause the patient to urinate more, which leads to excessive thirst. Within 5 to 10 years after diagnosis, the insulin-producing beta cells of the pancreas are completely destroyed, and no more insulin is produced.
The exact cause of type 1 diabetes is not known. Each year more than 13,000 young people are diagnosed with type 1 diabetes. New cases are less common among adults older than 20.
Type 2 diabetes usually develops in older, overweight individuals who become resistant to the effects of insulin over time. When type 2 diabetes is diagnosed, the pancreas is usually producing enough insulin but, for unknown reasons, the body cannot use the insulin effectively. This is called insulin resistance. This means that the insulin produced by your pancreas cannot connect with fat and muscle cells to let glucose inside and produce energy. This causes hyperglycemia (high blood glucose). To compensate, the pancreas produces more insulin. The cells sense this flood of insulin and become even more resistant, resulting in a vicious cycle of high glucose levels and often high insulin levels.
Inflammation is also common among those with type 2 diabetes. Inflammatory markers (chemicals in the body that lead to inflammation), such as interleukin-6 (Il-6) and C-reactive protein, have been found to be increased in those with type 2 diabetes.
Type 2 diabetes usually occurs gradually. Most people with type 2 diabetes are overweight at the time of diagnosis. However, the disease can also develop in lean people, especially the elderly.

Risk Factors

Type 1 diabetes
  • Family history of type 1 diabetes
  • Mother who had pre-eclampsia (a condition characterized by a sharp increase in blood pressure during the third trimester of pregnancy)
  • Family history of autoimmune diseases, including Hashimoto's thyroiditis, Graves disease, myasthenia gravis, Addison disease, or pernicious anemia
  • Viral infections during infancy, including mumps, rubella, and coxsackie
  • Child of an older mother
  • Northern European or Mediterranean descent
  • Lack of breastfeeding and consumption of cow's milk during infancy (although the theory is controversial and not widely accepted)
Type 2 diabetes
  • Family history of type 2 diabetes (one quarter to one third of all individuals with type 2 diabetes have a family history of the condition)
  • Age older than 45 years
  • Excess body fat, particularly around the waist
  • Sedentary lifestyle and high-fat, high-calorie diet
  • Abnormal levels of cholesterol or triglycerides in the blood
  • High blood pressure
  • History of gestational diabetes or polycystic ovarian syndrome (a hormonal disorder that causes women to have irregular or no menstruation)
  • African American, Hispanic American, or Native American (particularly Pima tribe in Arizona) descent
  • Low birth weight or a mother's malnutrition in pregnancy (this may cause metabolic disturbances in a fetus that lead to diabetes later in the child's life)
  • Depression is associated with a 60% increased risk of type 2 diabetes

Diagnosis

According to the American Diabetes Association, all pregnant women should be screened for gestational diabetes during their third trimester. People who are 45 years or older should have their blood glucose levels checked every 3 years. Those who have a high risk of developing diabetes (such as people with a family history of the disease) should be tested more often.
Different types of tests are used to diagnose diabetes: Random plasma glucose level, fasting plasma glucose level, and oral glucose tolerance test.
If the fasting glucose level is 100 to 125 mg/dL, the individual has a form of pre-diabetes called impaired fasting glucose (IFG), meaning that the individual is more likely to develop type 2 diabetes but does not have the condition yet. A level of 126 mg/dL or above, confirmed by repeating the test on another day, means that the individual has diabetes.
Other diagnostic tests for diabetes include fructosamine testing and hemoglobin A1c. The American Diabetes Association (ADA) recommends A1c as the best test to find out if an individual's blood sugar is under control over time. The test should be performed every 3 months for insulin-treated patients, during treatment changes, or when blood glucose is elevated. For stable patients on oral agents, health care professionals recommended testing A1c at least twice per year. The ADA currently recommends an A1c goal of less than 7%. Studies have reported that there is a 10% decrease in relative risk of microvascular complications (injuries to the small blood vessels throughout the body), such as diabetic nephropathy (kidney disease) or diabetic neuropathy (nerve damage), for every 1% reduction in hemoglobin A1c. Many nutritionally-oriented physicians look for a much lower A1c as the goal for their patients.
People with diabetes must closely monitor their blood sugar and see their doctor regularly. Self monitoring of blood glucose is done by checking the glucose content of a drop of blood. Regular testing tells you how well diet, medication, and exercise are working together to control your diabetes. Dieticians can also be an integral part of care.

Preventive Care

Type 1 diabetes
There is no proven way to prevent type 1 diabetes. However, research conducted in Finland suggests that adequate amounts of vitamin D, particularly in the first year of life, may decrease one's chances of developing type 1 diabetes within the first 30 years of life. In northern Finland (where the annual exposure to sunlight is very limited) researchers followed 10,000 infants for up to 30 years. Those given at least 2,000 IU of vitamin D per day (generally from cod liver oil) for the first year of life were significantly less likely to develop type 1 diabetes over 30 years than infants who were given less than that. Other studies have confirmed that doses of 2,000 IU or higher of vitamin D may have a strong protective effect against type 1 diabetes. For this reason, caretakers of infants and children at increased risk for type 1 diabetes might wish to consider supplementation. Experts suggest supplementing these individuals at the high end of current U.S. recommendations for vitamin D, which is 200 to 1,000 IU.
Type 2 diabetes
Considerable evidence from population based studies suggests that type 2 diabetes is highly preventable, particularly through exercise and weight management. Individuals who are physically inactive or overweight are much more likely to develop type 2 diabetes. Similarly, people who move from a non-Westernized country to a Westernized country (such as the United States, where more people are overweight and live sedentary lives) increase their risk for type 2 diabetes. Studies suggest that you do not need vigorous physical activity to lower your risk of diabetes; moderate, regular exercise, such as walking for 30 minutes most days of the week, is enough. In general, lifestyle changes recommended to treat diabetes may help prevent the condition as well.

Treatment Approach

The goal of diabetes treatment is to achieve and maintain healthy blood glucose levels. A major study called the Diabetes Control and Complications Trial (DCCT) found that people with diabetes who kept their blood glucose levels close to normal reduced their risk of developing major complications from the condition.
People with diabetes can use the following therapies to help manage their blood glucose levels and to prevent complications:
  • Lifestyle changes, such as a well-balanced diet and regular exercise
  • Medications, particularly insulin for individuals with type 1 diabetes and some people with type 2 diabetes
  • Supplements, including fiber and chromium
  • Relaxation techniques
  • Acupuncture for pain from nerve damage
  • Bariatric surgery, for people who are overweight and obese to help manage blood glucose levels
Lifestyle
People with diabetes can improve significantly from lifestyle changes, particularly diet and exercise. People with type 2 diabetes may even eliminate the need for medications when they make appropriate lifestyle changes.
Diet
The ADA recommends that people with diabetes consume a healthy, low-fat diet, rich in grains, fruits, and vegetables. A healthy diet typically includes 10 to 20% of daily calories from protein, such as poultry, fish, dairy, and vegetable sources. People with diabetes who also have kidney disease should work with their health care providers to limit protein intake to 10% of daily calories. A low-fat diet typically includes 30% or less of daily calories from fat, less than 10% from saturated fats and up to 10% from polyunsaturated fats (such as fats from fish).
Carbohydrates tend to have the greatest effect on blood glucose. The balance between the amount of carbohydrate eaten and the available insulin determines how much the blood glucose level goes up after meals or snacks. To help control blood glucose, people should watch how many carbohydrate servings they eat each day. Foods that contain a high amount of carbohydrates include grains, pasta, and rice; breads, crackers, and cereals; starchy vegetables, including potatoes, corn, peas, and winter squash; legumes such as beans, peas, and lentils; fruits and fruit juices; milk and yogurt; and sweets and desserts. Non-starchy vegetables, such as spinach, kale, broccoli, salad greens, and green beans, are very low in carbohydrates. Carbohydrate counting can ensure that the right amount of carbohydrate is eaten at each meal and snack. A dietitian can help each person work out a dietary plan that is right for them.
In addition, weight loss should be part of the plan for those with type 2 diabetes. Moderate weight loss (achieved by reducing calories by 250 to 500 per day and exercising regularly) controls not only blood sugars, but also blood pressure and cholesterol. People with diabetes who eat healthy, well-balanced diets do not need to take extra vitamins or minerals to treat their condition.
Exercise
Exercise plays an important role in both the prevention and management of diabetes because it lowers blood sugar and helps insulin work more efficiently in the body. Exercise also enhances cardiovascular fitness by improving blood flow and increasing the heart's pumping power, promoting weight loss and lowering blood pressure. However, exercise has the most value when it's done regularly, at least 3 to 4 sessions per week for 30 to 60 minutes per session. As little as 20 minutes of walking, 3 times a week, has a proven beneficial effect. People with type 2 diabetes who exercise regularly have been shown to lose weight and gain better control over their blood pressure, thereby reducing their risk for cardiovascular disease (a major complication of diabetes). Studies have also shown that people with type 1 diabetes who exercise regularly reduce their need for insulin injections.
Despite the benefits of exercise, many people have difficulty sticking with an exercise program for a long period of time. Health care providers can help develop suitable routines, as well as strategies that may improve adherence to such routines. Anyone with long-standing diabetes should have a thorough screening before starting an exercise program and receive careful monitoring from a doctor.
Medications
Medications for diabetes must always be used in combination with lifestyle changes, particularly diet and exercise, to improve the symptoms of diabetes. Medications include insulin, oral sulfonylureas (like glimepiride, glyburide, and tolazamide), biguanides (Metformin), alpha-glucosidase inhibitors (such as acarbose), thiazolidinediones (such as rosiglitazone) and meglitinides (including repaglinide and nateglinide). A new agent in the fight against diabetes, exenatide (Byetta), is an injectable drug that reduces the level of sugar (glucose) in the blood. In clinical studies, patients treated with exenatide achieved lower blood glucose levels and lost weight. Exenatide was approved by the U.S. Food and Drug Administration in May 2005. Several other agents are under investigation including sodium-glucose co-transporter 2 inhibitors, G-protein-coupled receptor agonists, and the balanced dual perpexisome proliferator-activated receptor agents.
Nutrition and Dietary Supplements
Considerable research has been conducted on the relationship between diabetes and specific nutrients and dietary supplements. Dietary supplements may increase the effects of blood sugar-lowering medications, including insulin. When considering the use of supplements or making dietary changes, be sure to discuss these changes with your health care provider to ensure safety and appropriateness.
Supplements with Blood Sugar Lowering Effects
Chromium. Found in a variety of foods and supplements, including liver, brewer's yeast, cheese, meats, fish, fruits, vegetables, and whole grains, chromium appears to enhance the body's sensitivity to insulin. Researchers believe that chromium helps insulin pull glucose from the bloodstream into the cells for energy. The benefit of chromium supplements for diabetes has been studied and debated for years. While some studies show no beneficial effects of chromium use for people with diabetes, other studies have shown that chromium supplements may reduce blood glucose levels in individuals with type 2 diabetes and reduce the need for insulin in those with type 1 diabetes. Most Americans get at least 50 mcg of chromium in their diets each day. The National Research Council estimates that intakes of 50 to 200 mcg per day are safe and effective. Clinical studies showing improved blood sugar control for those with diabetes have used doses of chromium picolinate ranging from 200 to 1,000 mcg per day. However, until human studies of long-term safety are conducted with higher doses, it is best to use 200 mcg or less per day. Chromium may interact negatively with insulin and thyroid medicines. Speak with your doctor if you have a history of kidney or liver disease, or are being treated for a psychiatric disorder.
Magnesium. Several clinical studies have demonstrated a strong association between low levels of magnesium in the blood and type 2 diabetes. However, researchers are still unclear about the cause and effect in that association. They are investigating whether low magnesium levels worsen blood sugar control in people with type 2 diabetes or whether diabetes causes magnesium deficiencies. Some experts believe that low magnesium levels worsen blood sugar control and that foods rich in magnesium (such as whole grains, green leafy vegetables, bananas, legumes, nuts, and seeds) or magnesium supplements may promote healthy blood glucose levels. At least one small study suggests that taking magnesium supplements may improve the action of insulin and decrease blood sugar levels, particularly in the elderly. People with severe heart disease or kidney disease should not take magnesium supplements. People with diabetes should talk with their health care provider about whether it is safe and appropriate to take magnesium supplements. Magnesium can interact with some medications. Magnesium may lower blood pressure and cardiac output, and potentially interact with some cardiac medications. Excess magnesium can cause diarrhea.
Fiber. Studies suggest that a high-fiber diet may help:
  • Prevent development of type 2 diabetes
  • Lower average glucose and insulin levels in people who already have type 2 diabetes
  • Improve cholesterol and triglyceride levels in those with diabetes
In a large-scale study of nurses in the United States, women who consumed the most whole grain foods in their diets were nearly 40% less likely to develop diabetes than women who consumed the least. People with irritable bowel syndrome, inflammatory bowel disease, or other digestive issues should speak with their doctor before adding fiber to their diet.
Studies have also shown that cholesterol levels improved in people with type 2 diabetes after they took supplements of a soluble fiber known as psyllium (Plantago psyllium).
Beta-glucan is a soluble fiber derived from the cell walls of algae, bacteria, fungi, yeast, and plants. It is commonly used for its cholesterol-lowering effects. There are several human trials supporting the use of beta-glucan for glycemic (blood sugar) control.
Vanadium. Vanadium is an essential trace mineral present in the soil and in many foods. It appears to mimic the action of insulin and, in a number of human studies, vanadyl sulfate (a form of vanadium) has increased insulin sensitivity in those with type 2 diabetes. Animal studies and some small human studies also suggest that vanadium may lower blood glucose to normal levels (reducing the need for insulin) in people with diabetes. One preliminary clinical study found that people with diabetes using insulin who were given vanadium were able to lower their dose of insulin. Vanadium may slow blood clotting, so people who take blood-thinning medication such as warfarin (Coumadin) and aspirin should check with their doctor before adding vanadium supplements to their regimen. People with a history of kidney issues should speak with their doctor before using vanadium supplements.
Melatonin. Melatonin is a natural hormone secreted in the brain. Studies link low melatonin secretion with an increased risk of developing type 2 diabetes. Melatonin can cause sleepiness and potentially interact with some psychiatric medications and medications used to treat insomnia.
Antioxidants
Antioxidants such as beta-carotene and vitamin C are scavengers of free radicals, unstable and potentially damaging molecules generated by normal chemical reactions in the body. Free radicals are unstable because they lack one electron. In an attempt to replace this missing electron, the free radical molecules react with neighboring molecules in a process called oxidation. Some studies suggest that people with diabetes have elevated levels of free radicals and lower levels of antioxidants. Preliminary clinical studies show that the following antioxidants may improve diabetes (by returning blood glucose levels to the normal range) and reduce the risk of associated complications:
  • Vitamin E
  • Selenium
  • Zinc
  • Quercetin
Two additional substances that show preliminary evidence to possibly help control blood sugar include:
  • Biotin (a B-complex vitamin). Possibly helpful for type 2 diabetes; brewer's yeast is a good source of biotin.
  • Vitamin B6. Possibly helpful for both type 1 and type 2 diabetes.
Supplements with Cardiovascular Effects
Since insulin resistance is often associated with cardiovascular disease, people with diabetes may benefit from nutrients that help manage elevated blood lipid levels, high blood pressure, or heart failure. Although the following supplements have been shown to improve cardiovascular health, there is some concern that they may raise blood glucose levels, and they may interact with certain medications. People with diabetes interested in trying the following supplements should first consult with their health care providers:
  • Coenzyme Q10 (CoQ10)
  • Niacin
  • Omega-3 fatty acids
Although clinical studies have not shown that either CoQ10 or omega-3 fatty acid supplements raise blood sugar levels, people with diabetes should discuss the safety and appropriateness of using these, or any supplements, with their health care provider or pharmacist, particularly if they are taking other medications. CoQ10 can potentially increase the clotting tendency of blood while omega-3 fatty acids can potentially decrease it. Niacin in certain amounts can potentially damage the liver. Work with your physician to find the types and amounts of supplements that are right for you.
In addition, the following antioxidants have been shown to improve cholesterol levels in people with type 2 diabetes. Work with your doctor to see if these are appropriate for you as they can potentially interact with other medications and may potentially worsen other medical conditions:
  • Beta-carotene
  • Vitamin C (1000 mg per day)
  • Vitamin E (800 IU per day)
Several clinical studies have also found that elevated manganese levels may help protect against LDL oxidation (a process that contributes to the development of plaque in the arteries).
Herbs
People have long used plant-based medicines in the treatment of diabetes. For instance, the plant extract guanidine, which lowers blood glucose, prompted the development and use of biguanides, a commonly used oral medication for diabetes. Other herbs may have a role in the management or prevention of diabetes. Always talk to your health care provider about any herbs you consider using. Some herbs may interact with medications and some may lower your blood sugar. When combined with blood sugar-lowering medications, some herbs can bring your blood sugar to a dangerously low level.
Herbs that may have a role in the management or prevention of diabetes include:
  • Bitter melon (Momordica charantia). Bitter melon has traditionally been used as a remedy for lowering blood glucose in patients with diabetes. Preliminary clinical studies have indicated that bitter melon may decrease serum glucose levels. Bitter melon can be extremely dangerous to take when pregnant.
  • Fenugreek seeds (Trigonella foenum graecum). Fenugreek seeds, a spice found in many curry preparations, are high in fiber and have been shown to regulate glucose and improve lipid levels in both animals and humans. In two small studies of people with either type 1 or type 2 diabetes, fenugreek seed powder lowered blood glucose and improved levels of blood cholesterol and triglycerides, among other beneficial effects. Fenugreek may interact with blood-thinning medications, such as warfarin (Coumadin).
  • Gymnema (Gymnema sylvestre). Preliminary human research reports that gymnema may be beneficial in patients with type 1 or type 2 diabetes when it is added to diabetes drugs being taken by mouth or to insulin. Gymnema may alter the ability to detect sweet tastes.
  • Cinnamon (Cinnamomum zeylanicum). In a clinical study of 60 people with type 2 diabetes, intake of 1, 3, or 6 grams of cinnamon per day reduced glucose, triglyceride, LDL cholesterol, and total cholesterol levels. Other clinical studies have found similar results. As a result, experts claim that cinnamon may play an important role in regulating blood sugar in people with diabetes.
  • American ginseng (Panax quinquefolium). Although both Asian (Panax ginseng) and American (Panax quinquefolium) ginseng appear to lower blood glucose levels, only American ginseng has been studied scientifically. Several clinical studies report a blood sugar-lowering effect of American ginseng (Panax quinquefolium) in individuals with type 2 diabetes, both on fasting blood glucose and on postprandial glucose levels. One clinical study found that people with type 2 diabetes who take American ginseng before or together with a glucose meal experience a reduction in glucose levels after they consume the meal. American ginseng may not be appropriate for people with autoimmune disease, and may interact with several medications, including blood-thinning medications, such as warfarin (Coumadin), among others. People with a history of hormone-sensitive cancers should only use ginseng under the guidance of their physician.
Acupuncture
Some researchers speculate that acupuncture may trigger the release of natural painkillers and reduce the debilitating symptoms of a complication of diabetes known as neuropathy (nerve damage). In one clinical study of people with diabetes suffering from chronic, painful neuropathy, acupuncture reduced pain and improved sleep in 77% of the participants and eliminated the need for pain medications in 32% of the participants. Given these findings, acupuncture may be a reasonable option for people with diabetes who have neuropathy, and either find no symptom relief, or develop side effects from conventional drug treatment.
Mind-Body Medicine
Stressful life events can worsen diabetes in several ways. For example, stress stimulates the nervous and endocrine systems in ways that increase blood glucose levels and disrupt healthful behaviors (increasing the chances that an individual may consume excess calories and limit his or her physical activity, a pattern that leads to elevated blood glucose).
It makes sense then to consider stress management as part of the treatment and prevention of diabetes. Clinical studies have reported that people with diabetes who participate in biofeedback sessions (a technique that increases awareness and control of the body's response to stress) are more likely to reach target blood glucose levels than those who do not receive biofeedback. Although other studies have produced conflicting results, researchers and clinicians agree that long-term stress is likely to worsen diabetes and that biofeedback, tai chi, yoga, and other forms of relaxation may help motivate people with diabetes to change their habits to manage their condition.

Other Considerations

Pregnancy
Women of child-bearing age who have diabetes should consult an endocrine specialist about the benefits of managing glucose levels before trying to conceive.
About 4% of all pregnant women in the United States are diagnosed with gestational diabetes. Risk factors for developing diabetes while pregnant include:
  • Modest weight gain prior to pregnancy (11 to 22 pounds or more)
  • Family history of diabetes
  • Tobacco use
  • African American, Hispanic American, or Asian ancestry
  • Age older than 50 at conception
Normalizing glucose levels in women with gestational diabetes reduces their risk of complications, such as having an overweight baby, birth trauma, or the need for cesarean section. If the mother's glucose levels are uncontrolled, an infant can be stillborn or suffer from complications, including defects of the brain or central nervous system, an abnormally large body or organs, heart or kidney abnormalities, asphyxia, respiratory distress, and heart failure.
If dietary restrictions fail to improve glucose levels, a woman with gestational diabetes may need insulin. Women should not take oral diabetes medications during pregnancy. Women who develop gestational diabetes may experience the condition again in subsequent pregnancies. Gestational diabetes also increases the risk for developing type 2 diabetes later in life.
Depressive symptoms are associated with an increased risk of diabetes. The association cannot be explained by the use of antidepressant drugs or being overweight. Depression is an important risk factor for diabetes.
Prognosis and Complications
People who maintain tight control over their blood glucose levels can prevent or delay the development of long-term complications from diabetes. Type 1 diabetes generally has more complications than type 2 diabetes.
Long-term complications of diabetes may include:
  • Heart disease and stroke
  • Vision loss and blindness
  • Kidney disease
  • Neuropathy (nerve damage)
  • Foot ulcers and infections
  • Skin problems, including bruising, dryness, itching, hair loss, warts, gangrene (tissue death), and skin ulcers
  • Cognitive impairment
