Carbs and diabetes

When it comes to the link between carbs and diabetes, quality matters. After analyzing dietary data from 200,727 participants who were enrolled in the Nurses’ Health Study, the Nurses’ Health Study II or the Health Professionals Follow-up Study, researchers from the Harvard T.H. Chan School of Public Health found replacing 5% of energy from saturated fat with 5% of energy from low-quality carbohydrates (such as refined grains and sugary drinks) was linked to a higher risk for type 2 diabetes. In better news, swapping 5% of energy from saturated fat with high-quality carbohydrates from whole grains was associated with a lower risk.

It’s worth noting that the investigation, published in Current Developments in Nutrition, also determined that isocaloric substitution of low-quality carbs with other macronutrients was not associated with type 2 diabetes risk. Conversely, when dietary calories from high-quality carbohydrates replaced some of those from fats and proteins (unsaturated fat, trans fat, animal protein and vegetable protein), there was also a lower diabetes risk.
