Whole Grains Improve Insulin Sensitivity
Whole grains improve insulin sensitivity, according to a study appearing in tomorrow’s American
Journal of Clinical Nutrition. Insulin sensitivity is a measure of the body’s efficiency in
clearing sugar from the bloodstream. Individuals with better insulin sensitivity have reduced risk
of diabetes, heart disease, stroke, and cancer.
The Insulin Resistance and Atherosclerosis Study included 978 middle-aged adults with either normal
or impaired glucose tolerance. Participants whose diets included the most whole-grain foods--dark
breads (e.g., whole wheat, rye, pumpernickel), bran or granola cereals, and cooked cereals--had
significantly better innsulin sensitivity, compared to those who tended to skip these foods.
This effect of whole grains appears to come mostly from their fiber and magnesium. However,
evidence suggests that the short-chain fatty acids produced as grains are digested also contribute
to the effect.
The study is not yet on Medline. Here is the reference:
Liese AD, Roach AK, Sparks KC, Marquart L, D’Agostino RB Jr., Mayer-Davis EJ. Whole-grain intake
and insulin sensitivity: the Insulin Resistance Atherosclerosis Study. Am J Clin Nutr
2003;78:965-71.
