Sweet Talk

Medical researchers say we have more control over our blood sugar levels than we may realize. Scores of published studies support the use of a variety of nutritional and herbal supplements in combination with a high-fibre, nutritionally balanced diet as the best natural approach to blood sugar control.

Here’s what the scientists say about those products and how they work. But first an important reminder: people taking prescribed medications for a blood sugar related condition need to inform their physician when taking natural remedies, in case their medications need adjustment.

Eight Sweet Stoppers

1. Alpha-lipoic acid (ALA) is a sugar-busting antioxidant that inhibits the destructive enzyme aldose reductase from promoting advanced glycation. Advanced glycation is the abnormal attachment of sugar to protein, which can damage blood vessels, kidneys, nerves, and eye lenses, especially in people with diabetes. ALA is only suggested if you have high blood sugar (diabetes), not low blood sugar (hypoglycemia). The starting dosage is 100 mg daily.

2. Bitter melon (Momordica charantia), a tropical fruit from Asia, is used medicinally to lower blood glucose levels. In 2004, the journal Medical Hypotheses reported that “bitter melon has the potential to down-regulate [suppress the response to] insulin” and “it may have preventive value with respect to a wide range of disorders in which hyperinsulinemia [the presence of excess insulin in the blood] plays a pathogenic role–and possibly could even favourably impact the aging process.” Follow dosage recommendations on the label.

3. Chromium GTF, an essential trace mineral and the biologically active component of glucose tolerance factor, regulates normal insulin activity and function. More than any other mineral, insulin’s effects on carbohydrate, fat, and protein metabolism depend upon the maintenance of adequate chromium stores within the body to help transport glucose into cells. Most studies recommend taking between 200 to 1000 mcg daily.

4. Glucomannan fibre (Japanese konjac root) is the primary active ingredient in popular fibre-based smoothie and shake products formulated for blood sugar control and weight loss. One such product developed through the University of Toronto improved insulin sensitivity by 40 percent. Results of a placebo-controlled, double-blind study on the effects of glucomannan on diabetics was reported in February 2003 in The Journal of the American College of Nutrition and recommended its use as part of the treatment plan for diabetics. All kinds of dietary fibre are useful in controlling blood sugar levels, so be sure to eat at least 40 grams of fibre from whole grains, fruits, vegetables, nuts, and seeds every day.

5. Magnesium is another key mineral influencing blood sugar levels. Researchers have generally concluded that the lower magnesium levels are in the body, the higher the blood sugar levels tend to be. They also found that magnesium deficiency promotes insulin resistance in rodents and in humans, whereas supplemental magnesium plays a role in preventing type 2 diabetes and improves insulin sensitivity. The actual biochemical role of magnesium in support of insulin function is not well understood but, fortunately, the significant improvements in blood sugar levels from taking a magnesium supplement or eating magnesium-rich foods such as nuts, seeds, and legumes are well documented. On average, a daily intake of 400 mg magnesium (citrate, chelate, or glycinate) is recommended.

6. Prickly pear (Opuntia spp.) is a family of cacti native to Mexico and parts of the Mediterranean. Called nopal in Spanish, prickly pear is another example of a traditional food with valuable therapeutic properties. Two European studies found that an extract derived from the fibre of the fruit improved overall blood chemistry, including blood glucose, cholesterol, and triglycerides. With such positive results, researchers concluded it had significant potential for treating metabolic syndrome. Follow dosage recommendations on the label.

7. Soy protein, whether you’re a guy or a gal, is good news for your blood glucose. A study published in Hormone and Metabolic Research in May 2005 showed that soy protein had a markedly positive effect on improving insulin sensitivity. In December 2004 the Journal of Women’s Health published results of a study conducted by the Department of Family Medicine at National Taiwan University Hospital in Taipei that showed soy isoflavones from soy protein lowered fasting blood glucose and insulin levels in post-menopausal women.

8. Low vitamin C levels in the blood may be an indication for pregnant women that they are at increased risk for gestational diabetes. The Journal of Reproductive Medicine in April 2004 reported that women with gestational diabetes had a 10 percent lower daily dietary vitamin C intake. Women who reported daily vitamin C intake of less than 70 mg were 3.7 times more likely than the other women in the study to develop gestational diabetes. Women with the lowest levels of ascorbic acid experienced a 12 times greater risk of developing the disease compared to women with the highest levels of plasma ascorbic acid.

These are eight of the major natural products studied in relation to controlling blood sugar levels. The next time your sweet cravings get out of hand, blend up a fresh fruit smoothie and get walking to your local health food store. A wide selection of wholesome foods, supplements, and herbs are readily available to help you take back control of your blood sugar levels.

Caring for Your Diabetic Feet
Diabetes is the leading cause of foot amputations not related to injuries. Each year, thousands of diabetics have to learn to live without one of their precious limbs.

Diabetic Discipline-10 Basic Rules
1.Be aware of what you eat. Diabetics convert everything they eat, even fat and protein, into sugar. The more they eat, the more sugar they have in their systems. The answer is to curb eating indulgence. 2.Don't overeat.

Vitamin C
If we are serious about slaying the current Goliath "sickness industry," as opposed to the "health industry," we must arm ourselves with the truth about vitamin C.

Anti-Cancer Antioxidants
Imagine the cells in your body turning brown just like an apple does when exposed to the oxygen in the air.

The 21st-Century Epidemic
Diabetes is one of the biggest drains of our society's resources -both financial and human. The total economic toll of diabetes in Canada is an absolutely staggering excess of over $10 billion annually.

The Stress and Diabetes Link
Diabetes is a disease of civilization. It is a disease of unhealthy eating patterns, low levels of physical activity, and chronic emotional stress. Canada's aboriginal people provide a dramatic example. A few decades ago, diabetes was virtually unknown among the Cree nation of northwestern Ontario.

Sweet Little Lies
Consumers have filed a $350 million class action against the world's most-used chemical sweetener in a bid to expose aspartame's deadly side effects.

Your Detox-Product Shopping List
From the car fumes we breathe to the pesticide residues on our foods, toxic contaminants are, sadly, a daily reality. Your local health food store is your best source of the wide range of natural foods, herbs, and supplements needed to support natural detoxification.

Stressed Out
If you're like so many other people, you're stressed from the moment you wake up until you hit the sack some 16 hours late.

Forever Young
All of us want to have longer and healthier lives, and while some of us are dealt a better hand than others in life's genetic lottery, there are many ways we can maximize the potential we are born with.

The Energy Trio
When we are young, our bodies have a tremendous ability to repair. This is called anabolic metabolism - the ability to repair our cells faster then they break down. Anabolic metabolism also creates a great atmosphere for fat burning and muscle enhancement. In other words, instead of merely living, we feel truly alive.

Top 10 Supplements
In June 2002 the Journal of the American Medical Association published an article that concluded nutritional deficiencies are an important cause of chronic disease.

Help for Diabetes
Supplements can help diabetics regulate blood sugar levels. In particular, vanadyl sulphate and chromium are effective individually or in formulas that also include herbal extracts and micronutrients.

Alkalinity
Your brain and body are extremely sensitive to the slightest change in the pH level of your body's vital fluids. A pH of less than seven is considered acidic, and more than seven is considered alkaline.

Vitamin C

Diabetes and Metabolism
Dr. Boyd Eaton, an expert in the diet of early man, believes that the less you eat like your ancestors, the more susceptible you'll be to many of the diseases of modern civilization-heart disease, arthritis, cancer, and diabetes.

Dealing with Diabetes
In the past 30 years, the rates of those diagnosed with diabetes, in both the young and old, have increased at such an alarming pace that it is now considered a healthcare epidemic. The World Health Organization says the situation is serious worldwide, with more than 177 million people currently diagnosed with diabetes.

Fibre-Licious
The increasing age of our population puts more people at risk of diabetes, but poor diet and lack of exercise are also contributing factors. Greater understanding of the risk factors for this disease can prevent a diabetes diagnosis.

Preventing Osteoporosis
While we think of a stooped-over old woman as symbolic of osteoporosis, this debilitating disease occurs over a lifetime. If either parent or any of your siblings have had an osteoporotic fracture, your risk for the disease is doubled, but that doesn't mean it's inevitable.

The News About Chromium
Chromium is an essential micronutrient required for proper insulin function, healthy blood-sugar levels, and carbohydrate, fat, and protein metabolism. However, many North Americans are deficient because of poor diets, that is, over-consumption of simple carbohydrates and refined sugars that are lacking in chromium.

Full of Beans
Blood sugar levels are easy to manage with a diet that focuses on whole foods and beans, which consistently appear on the low end of the glycemic index (a measure of how a given food will raise blood sugar when compared to pure glucose). Beans are an excellent source of protein, but they also contain protective fibre; for example, one cup (250 mL) of chickpeas provides 11 grams of fibre.

Vitamin C Instead Of Vaccines

Vitamin C Prevents Heart Disease

Vitamin C Fights Cancer

Eating Our Way to a New Epidemic
A surge in obesity in North America and a sedentary lifestyle are two of the major factors contributing to this rising epidemic. People are literally poisoning themselves by eating excessive amounts of all the wrong foods. Products such as refined, sugared, processed and caffeinated carbohydrates are causing the blood sugar of many to become dangerously uncontrollable.

Heartfelt Shopping
We've all heard the morbid statistics telling us heart attacks and strokes are the top killers of Canadian men and women. However, heart disease is usually preventable. Rarely do the conditions and symptoms leading to heart disease require more than a dedicated change of habits.

A Friend of Vitamin C
Walking through the local mall I spot my friend Amanda in our favourite health food store. She appears to be stocking up on echinacea, but I head straight for the vitamin C; I have the sniffles and I've been under a lot of stress lately and vitamin C aids both-and much more.

Profile of Dr. Andrew Weil
Andrew Weil is definitely changing the face of medicine. His familiar, white-bearded face has beamed at us from the cover of TIME magazine twice in the last nine years, most recently last October when his new book, Healthy Aging (Knopf, 2005) hit the stands.

Diabetes Dilemma
Diabetes is now considered a public health problem of enormous proportions. The most effective treatment of diabetes requires the utilization of lifestyle, dietary, and nutritional supplement strategies. Controlling blood sugar levels and promoting good health with natural medicine are quite simple.

Beyond Bones
Calcium and magnesium are essential minerals for good health, and we often hear about their benefits to our bones. But these vital nutrients are involved in many other body processes as well. In addition to building strong bones and teeth, it strengthens muscle contraction, improves nerve transmission and blood clotting, regulates heart beat, and activates enzymes.

Beauty Without Injections
In their search for quick fixes to defy the signs of aging, many people turn to facial injections. The injected substances can include anything from a protein produced by the same bacteria that causes botulism, to fat, collagen, and even silicone to fill in wrinkles.

Back to Basics
Building your strongest nutritional foundation begins with two basic steps: eating a balanced nutritious diet and taking a high-quality daily multiple vitamin and mineral supplement. This back-to-basics strategy has proven effective for young and old alike.

Unscramble the Number
Until relatively recently, experts incorrectly assumed that all simple carbohydrates digested quickly, causing a rapid rise in blood sugar, and that all starches digested slowly, causing a gradual rise in blood sugar. High blood sugar and insulin levels have been associated with insulin resistance, hypertension, strokes, and cardiovascular disease.

Beauty-Inside and Out
BeautyThere are healthy strategies that keep you feeling good, and the natural outcome of feeling good is looking good-no matter what your age. Eating well, exercising, and taking the right supplements help promote a healthy body-and a healthy look. Why not be beautiful inside and out?

Fighting Avian Flu
Homeopathy-light years ahead of allopathic (conventional) medicine-has already successfully introduced an influenza remedy made from the hearts and livers of wild ducks. This remedy is still in use today to fight annual winter flu.

Dodge Diabetes
Diabetes is a chronic health problem that involves elevated blood sugar levels. Proper nutrition, exercise, and dietary supplements normalize blood sugar levels and weight preventing diabetes. Your diet should be high in fibre, found in vegetables, nuts, seeds, and whole grains. More specifically, your diet should include water-soluble fibre.
