‘Low Glycemic’ Diets May Not Provide Significant Health Advantage
(NEW YORK) — Diets that focus on low impact on blood sugar may not have a significant impact on risk of heart disease or diabetes.
Researchers from Johns Hopkins University and Brigham and Women’s Hospital in Boston looked at data from 163 healthy adults who were either overweight or obese at five-week intervals. Each participant ate either a “low glycemic diet” which focuses on foods that have low impact on blood sugar, or a “high glycemic diet.”
The study, published in the Journal of the American Medical Association, found that those participants who ate a diet with low glycemic indexes did not have significant improvement in their cardiovascular risk factors and often had increased levels of “bad” LDL cholesterol and decreased sensitivity to insulin.
The study was done over a short period of time, so researchers did not analyze medical outcomes, such as the development of diabetes or the rate of occurrence of heart attacks, but rather studied the risk factors associated with those outcomes.
