Blueberries Reduce Belly Fat and Diabetes Risk

berries, blueberry, blueberries, heart disease, cardiovascular disease, diabetes, metabolic syndrome, obesity, belly fat, abdominalEating blueberries could help you get rid of belly fat, and a blueberry-enriched diet could stem the conditions that lead to diabetes.

New research gives tantalizing clues to the potential of blueberries in reducing risk factors for cardiovascular disease and metabolic syndrome. The effect is thought to be due to the high level of naturally occurring antioxidants called phytochemicals contained in blueberries.

Researchers studied the effect blueberries had when added to the diet of rats. After 90 days, rats that received a blueberry-enriched diet had less abdominal fat, lower triglycerides, lower cholesterol, and improved fasting glucose and insulin sensitivity.

Dr. Mercola''s CommentsDr. Mercola's Comments:

The benefits of eating fruits and vegetables are undisputed, but modern research keeps showing us just how they help you to optimize your health.

Berries are some of the most nutritious foods on the planet. In the case of blueberries, naturally occurring phytochemicals such as anthocyanins can do wonders to normalize and improve your health. And berries, in general, are also high in fiber and relatively low in sugar, so they won’t stimulate severe insulin swings if eaten in moderation.

Berries are best eaten in their raw, natural state, as heating and freezing can damage antioxidants. However, some antioxidants will remain even after heating or freezing.

The Blue Wonder Berry

Blueberries contain vitamins A and C, zinc, potassium, iron, calcium and magnesium, and are high in fiber and low in calories. Additionally, researchers at the USDA Human Nutrition Center (HNRCA) have ranked blueberries number one in antioxidant activity when compared to 40 other fresh fruits and vegetables, so there are many reasons for adding blueberries to your diet.

They are associated with numerous health benefits, including natural protection against:

And, according to the latest research presented in the article above, blueberries may also offer protection against metabolic syndrome (which can lead to diabetes), the accumulation of abdominal fat, and reduce your risk of cardiovascular disease.

These findings strengthen previous discoveries of the berry’s powerful impact on cardiovascular health.

Because in addition to anthocyanin – which gives the berry its deep blue color -- blueberries also contain an antioxidant compound called pterostilbene, which has been found to reduce cholesterol as well as prescription drugs. (It shares similar qualities to another cholesterol-reducing antioxidant, resveratrol, which is found in both grapes and red wine.)

As an interesting side note, another unusual way to benefit from blueberries is to add them to your ground beef before cooking (ideally at low temperatures) as they help prevent cancer-causing heterocyclic amines (HCA) from forming in the meat.

How Blueberries Protect Against Metabolic Syndrome

Metabolic syndrome -- also sometimes referred to as pre-diabetes -- is a conglomerate of health problems that include high amounts of abdominal fat, high blood pressure, elevated blood sugar, and high triglycerides. When combined, these conditions increase your risk of cardiovascular disease, heart attacks, strokes and diabetes.

In this latest study, rats that consumed blueberry-enriched powder as two percent of their diet had less abdominal fat, lower triglycerides, lower cholesterol, and improved fasting glucose and insulin sensitivity after 90 days, compared to the control group.

Additionally, they found that blueberry intake affected genes related to fat-burning and storage. And when they looked at muscle tissue, they saw alterations in genes related to glucose uptake.

This is interesting as another recent study concluded that metabolic syndrome is likely not caused primarily by abdominal fat, as previously thought, but rather by insulin resistance in your skeletal muscle, which leads to changes in energy storage – which in turn leads to metabolic syndrome.

Insulin resistance is clearly a key factor in metabolic syndrome, and as I’ve stated on countless occasions, the prescription for insulin resistance is diet and exercise. 

It’s good to know that eating something as delicious as blueberries can actually help improve your insulin sensitivity.

The Two Best Prescriptions Against Belly Fat and Diabetes

Exercise is your number one ally here, both for shedding unwanted body fat and normalizing your insulin levels.

It can also help you sleep better, which turns out to be another important factor if you want to avoid excess pounds around your midsection. In my recent article 4 Ways to Shed Belly Fat, I explain the little-known connection between your sleeping habits and your body’s ability to shed abdominal fat.

Keep in mind that when you’re exercising to achieve weight loss, you’ll want to focus on weight bearing exercises, as muscle burns calories quite efficiently. In my experience, non-weight bearing exercises, like swimming and bicycling, are not as efficient or effective for weight loss. You’ll typically need to exercise four times as long in these activities to receive the same benefit of running or using an elliptical machine, or performing other aerobic activities.

And, to really maximize your weight loss efforts, make sure you include high-intensity interval exercises and strength training in your program.

When it comes to diet, you’ll clearly want to stay away from any foods that raise your insulin levels, namely grains and sugars, and of course, processed foods.

But in addition to that, perhaps the most effective way of making sure you’re eating the optimal diet for you is to determine your specific nutritional type. Because what’s healthy for others may not necessarily be healthy for you, and vice-versa.

When battling either belly fat or diabetes – or both -- remember that controlling your insulin levels is as important to optimizing your weight as it is to protecting you against diseases like diabetes.

Because as your insulin levels increase, your body starts to store carbohydrates as fat while at the same time not releasing stored fat. This makes it impossible for you to use your own stored body fat for energy. So excess refined and processed carbohydrates in your diet (such as breads and pasta) not only make you gain weight, they make sure you keep that weight on.

By cutting grains and sugars from your diet, combined with a regular exercise program, you can significantly improve your chances of successful weight loss, and effectively protect yourself against diabetes and a whole host of other diseases.

Can Dogs Smell Cancer?

“All over the world, major universities are researching the therapeutic value of pets in our society and the number of hospitals, nursing homes, prisons and mental institutions which are employing full-time pet therapists and animals is increasing daily.” ~ Betty White, American Actress, Animal Activist, and Author of Pet Love

dog_noseScienceDaily (Jan. 6, 2006) — In a society where lung and breast cancers are leading causes of cancer death worldwide, early detection of the disease is highly desirable. In a new scientific study, researchers present astonishing new evidence that man’s best friend, the dog, may have the capacity to contribute to the process of early cancer detection.

In this study which will be published in the March 2006 issue of the journal Integrative Cancer Therapies published by SAGE Publications, researchers reveal scientific evidence that a dog’s extraordinary scenting ability can distinguish people with both early and late stage lung and breast cancers from healthy controls. The research, which was performed in California, was recently documented by the BBC in the United Kingdom, and is soon to be aired in the United States.

Other scientific studies have documented the abilities of dogs to identify chemicals that are diluted as low as parts per trillion. The clinical implications of canine olfaction first came to light in the case report of a dog alerting its owner to the presence of a melanoma by constantly sniffing the skin lesion. Subsequent studies published in major medical journals confirmed the ability of trained dogs to detect both melanomas and bladder cancers. The new study, led by Michael McCulloch of the Pine Street Foundation in San Anselmo, California, and Tadeusz Jezierski of the Polish Academy of Sciences, Institute of Genetics and Animal Breeding, is the first to test whether dogs can detect cancers only by sniffing the exhaled breath of cancer patients.

In this study, five household dogs were trained within a short 3-week period to detect lung or breast cancer by sniffing the breath of cancer participants. The trial itself consisted of 86 cancer patients (55 with lung cancer and 31 with breast cancer) and a control sample of 83 healthy patients. All cancer patients had recently been diagnosed with cancer through biopsy-confirmed conventional methods such as a mammogram, or CAT scan and had not yet undergone any chemotherapy treatment. During the study, the dogs were presented with breath samples from the cancer patients and the controls, captured in a special tube. Dogs were trained to give a positive identification of a cancer patient by sitting or lying down directly in front of a test station containing a cancer patient sample, while ignoring control samples. Standard, humane methods of dog training employing food rewards and a clicker, as well as assessment of the dog’s behavior by observers blinded to the identity of the cancer patient and control samples, were used in the experiment.

The results of the study showed that dogs can detect breast and lung cancer with sensitivity and specificity between 88% and 97%. The high accuracy persisted even after results were adjusted to take into account whether the lung cancer patients were currently smokers. Moreover, the study also confirmed that the trained dogs could even detect the early stages of lung cancer, as well as early breast cancer. The researchers concluded that breath analysis has the potential to provide a substantial reduction in the uncertainty currently seen in cancer diagnosis, once further work has been carried out to standardize and expand this methodology.

This study was supported by the MACH Foundation (Fairfax, CA), Guide Dogs for the Blind (San Rafael, CA) and Frank and Carol Rosemayr (Kentfield, CA).

Oxidative Stress

Even though the average life expectancy in the United States has increased dramatically during this past century, our quality of life due to chronic degenerative disease has taken a major hit. We are essentially "living too short and dying too long". Most of us can simply look forward to suffering and dying from heart disease, cancer, stroke, diabetes, Alzheimer’s dementia, Parkinson’s disease, arthritis, macular degeneration, and the list goes on and on, unless we literally attack the underlying cause of all of these diseases—oxidative stress.

How long do you expect to live? Now envision what your last twenty years will look like. I can assure you my patients today are not as concerned with the number of years in their lives as they are the quality of life in those years. Who wants to live to a ripe old age if he or she cannot even recognize close family members because of Alzheimer’s dementia? Who looks forward to a decade or two of suffering severe joint or back pain due to degenerative arthritis?

One of my close friends told me recently that he simply wants to live until he dies. Is this your desire? It certainly is mine. That is why I recommend preventative rather than post-problem medicine--empowering people to avoid getting major diseases in the first place. Over the past seven years, I have changed my approach. I now strongly encourage and support my patients in taking a three-fold approach to health: eating well, practicing a consistent exercise program, and daily consuming high-quality nutritional supplements. I now use medication as a last resort—not as my first choice.

Do you fear growing old? Have you accepted chronic disease or pain as a given in your future? Are you willing to make necessary life changes to ensure your health? I believe a full and abundant physical life does not need to start slipping away at age forty. Each year of your life can be your very best. But first you must understand the war that is waging within every one of our bodies.

Oxygen is essential for life itself. But did you know it is also inherently dangerous to our existence? I call this the "dark-side" of oxygen. And as a result, we are essentially rusting both inside and out. The same process that causes a cut apple to turn brown or iron to rust is the cause of all the chronic degenerative diseases we fear and even the aging process itself.

Consider the aging of our skin. Oxidative stress is the cause of wrinkles, sagging skin, and age spots. The next time you are with a large gathering of people of different ages, observe closely the change you see in people’s skin. Aging is a process we all take for granted, but when you look more closely, and compare a baby’s face, to that of a grandparent’s, the effects of our largest organ being exposed to all the pollutants in the air, sunlight, and cigarette smoke is baffling. This aging of the skin is an outward manifestation of "oxidative stress," which is occurring within every cell in your body.

Over the past 7 years, I have reviewed well over 2,000 medical and scientific studies in regards to nutritional supplements and their affect on your health. These studies appearing in medical journals like the New England Journal of Medicine, Journal of the American Medical Association, British Lancet, and Annuals of Internal Medicine report that beyond any doubt the "root" cause of well over 70 chronic degenerative diseases is "oxidative stress." These are the "who’s who" of diseases we all fear and want to avoid; diseases like heart attacks, strokes, diabetes, cancer, arthritis, Alzheimer’s dementia, macular degeneration, lupus, MS, fibromyalgia, and chronic fatigue. "So what," you may be wondering, "is ‘oxidative stress’?"

Within every cell of the body is a furnace called the mitochondria. As oxygen is utilized within the furnace of the cell to create energy and life itself, occasionally a charged oxygen molecule is created, called a "free radical." This free radical has at least one unpaired electron in its outer orbit essentially giving it an electrical charge. If this free radical is not readily neutralized by an antioxidant it can go on to create more volatile free radicals, damage the cell wall, vessel wall, proteins, fats, and even the DNA nucleus of our cells. Chemically this reaction has been shown to be so volatile that it actually causes bursts of light within our bodies!

Imagine yourself in front of a crackling fireplace and I’ll give you the best illustration I have to explain the process of oxidation. The fire burns safely and beautifully most of the time, but on occasion out pops a hot cinder that lands on your carpet and burns a little hole in it. One cinder by itself doesn’t pose much of a threat; but if this sparking and popping continues month after month, year after year, you will have a pretty "ratty" carpet in front of your fireplace.

The fireplace represents the furnace of the cell (the mitochondria), the cinder is the charged "free radical," and the carpet is your body. Whichever part of your body receives the most free radical damage will be the first to wear out and potentially cause one of these degenerative diseases. If it’s your arteries, you could develop a heart attack or stroke. If it is your brain, you could develop Alzheimer’s dementia or Parkinson’s disease. If it’s your joints, you could develop arthritis.

Through biochemical research we’re learning that we are not defenseless against this attack on our body by free radicals. Antioxidants are like the glass doors or fine-wire mesh we place in front of our fireplace. The sparks are still going to fly but our carpet will then be protected. As you begin to imagine the war that is taking place within every cell in your body, you can envision the two opposing forces: the enemy--free radicals; and your allies--antioxidants and their supporting nutrients.

Living a healthy life becomes a matter of balance. You must have enough antioxidants available to readily neutralize the number of free radicals your body produces. If you don’t, "oxidative stress" will occur. When this oxidative stress is allowed to persist over a prolonged period of time, you will most likely develop a serious chronic degenerative disease.

Each of us must ask, "Am I getting enough antioxidants from my diet to protect myself from this onslaught of free radicals or do I need to be taking nutritional supplements?" This is the question that I’ve had to ask myself as I have spent countless hours researching medical literature. You see I was taught in medical school that you don’t need supplements—that you can get everything you need from a good, healthy diet. And this is what I told my patients for years. I was wrong.

Since balance is the key, we need to look closely at the individual players that are at war within. The number of free radicals you produce each and every day is never the same. All the pollutants in our air, food, and water dramatically increase the number of free radicals we produce. Enormous stress, excessive exercise, cigarette smoke, sunlight, radiation, and every drug prescribed greatly increases the number of free radicals produced in the body. In fact, there has never been a generation on this planet subjected to more oxidative stress than this present one. We are literally under attack from our polluted environment, stressful lifestyles, and over-medicated society.

This ongoing attack is depriving us of our most precious gift—our health. But God did not leave us defenseless against this onslaught by free radicals. In fact, we actually have our own army of antioxidants, which are able to neutralize free radicals and render them harmless. In generations past, these defense systems were sufficient. Unfortunately this is no longer the case. Our bodies’ defense systems need additional allies.

Most antioxidants come from vegetables and fruit. This creates a gap in our protection, because our foods have become significantly depleted in their content of antioxidants and supporting minerals as a result of mineral depletion in our soils, green harvesting, cold storage, foods that are highly processed, our poor food choices and food preparation.

At a time when we are under the heaviest attack from the environment around us, our natural defense systems are becoming overwhelmed and depleted. We must do all we can to rebuild our antioxidant systems with a healthy diet, but too you need to learn how complete and balanced nutritional supplementation with high quality supplements (cellular nutrition) is our best hope in winning this war within and protecting our health.
