Reader Response: Insulin Index

2093368235 79204e055cReader Pete asked for some thoughts on the “Insulin Index,” a measurement chart similar to the glycemic index. While the glycemic index calculates the relative blood sugar rise induced by given foods, the insulin index evaluates the insulin response generated by 38 different foods.

The insulin index, which first made its appearance in a 1997 American Journal of Clinical Nutrition article, was primarily the creation of Susanne Holt, a graduate student at the time and now a doctor. Interestingly, Holt, her supervisory co-authors, or other researchers haven’t chosen to conduct further research to update the “preliminary” results of their insulin index study since its creation eleven years ago now.

What Happens to Your Body When… You Haven’t Properly Trained for Your Marathon?

471551867 0734139ed3The marathon. An epic struggle of the individual against his/her own body. A kind of “Mt. Everest” for athletic practice, it exacts a sizable toll on anyone who dares attempt it. (The first marathon man died after all.)

The seasoned athlete knows and respects the physical claim of a marathon, and it is substantial even for the best trained. But marathons are becoming increasingly popular in the last few years. Once limited to the athletic elites and diehards, marathons are now the stuff of social events and charity drives. We’re all for the social element of sport, and we’re suckers for a good cause like anyone. But this recent popularity has changed the face (and emergency support requirements) of marathons. While we believe that everyone’s got to start somewhere, we definitely believe this ain’t the place.

Turmeric: A Spice for Life

Picture2 7The popular Asian cooking spice, turmeric, may help prevent diabetes and help beneficially influence body composition, according to a study slated to appear in an upcoming issue of the journal Endocrinology.

Previous research has suggested that turmeric and its anti-oxidative ingredient, curcumin, can help reduce inflammation, help heal wounds and relieve pain.

For the most recent study, researchers from the Naomi Berrie Diabetes Center at Columbia University Medical Center evaluated the use of turmeric on rodent models and found that those treated with the popular curry spice were “less susceptible to developing type 2 diabetes” based on the findings of a blood glucose level test and an assessment of glucose and insulin tolerance.

Dear Mark: Better Nutrient Forms

2153783207 2c615fe319Dear Mark,

What’s the story about certain kinds of vitamin C, calcium, etc.? Does it make any difference?

Because we live in a more complicated, modern world with chronic stress, pollution, etc., I always suggest wise supplementation for optimum health. The best supplementation is effectively comprehensive, properly balanced, and efficiently bioavailable. Some forms of some nutrients are simply more readily absorbed than others. Additionally, some forms of certain nutrients are easier on the digestive system than others, particularly in those with stomach sensitivity.

When it comes to food, you want the best your money can buy, and the same thing goes for supplementation. Different supplements (we’ll stick with “multivitamins” for now) fulfill their nutritional claims differently. Some forms of certain nutrients, generally the more bioavailable and stomach-friendly forms, are more expensive than less bioavailable or harsher forms.
