Week 11: Soy Protein & Diabetes
What Does Science Say About Soy Protein & Diabetes?
Like most dietary matters, there are differing opinions on the value of adding soy or isolated soy protein to the diabetic diet. However, it's now clear that there is scientific evidence to support the incorporation of soy protein into diabetes management. The U.S. Department of Agriculture (USDA) recently stated in a published study that, "In studies of human subjects with or without diabetes, soy protein appears to moderate hyperglycemia [high blood sugar] and reduce body weight, hyperlipidemia [high cholesterol/lipids], and hypersinsulinemia [high insulin levels due to high blood sugar], supporting its beneficial effects on obesity and diabetes."
Are All Sources Of Soy Protein Equal In Terms Of Their Health Benefits For People With Diabetes?
The short answer is no; you need to carefully incorporate soy protein in your diet. While the number of soy products on the shelf at the supermarket is growing rapidly, as are soy dietary supplements, nutritional experts still conclude that the best sources of soy protein are from whole foods like tofu, soybeans, and soy milk.
How Can I Best Incorporate Soy Protein Into My Diet?
As with any nutritional component that's being added to your meal plan, incorporate soy products in moderation and balance. For cardiovascular benefits, studies show that you need to consume 25g or more per day of soy protein, but you don't necessarily need that much to realize other benefits due to its low-fat, low-carb profile. Good sources of natural soy can be found on the shelves in supermarkets and health food stores in the form of tofu, soy milk, soy nuts, soy burgers, and soy puddings. Just be sure to read the label carefully as some commercially prepared soy products can have more harmful ingredients --- such as sugars as fats --- than healthy ones. Most medical experts recommend that you get your soy from natural foods, not from soy supplements.

There are very few conditions under which I will not ride my (road) bike. More than an inch of new snow, snow pack, and slush are the three major ones. That said, if the distance is short and familiar, and traffic is expected to be light, I'll take my chances. I was considerably less hesitant in my teens and twenties when I had two bicycles in my stable: a three-speed commuter and a 12-speed touring bike. My craziest experiences then were riding through what I later...
