Ongoing research also suggests that adding healthy fats and proteins, such as peanut butter or olive oil, to meals with foods that have a high GI may
slow the uptake of glucose, thus, lowering the food's GI.
They found that, in the condition where
glucose uptake into muscles is impaired, replacing saturated fats in the diet with polyunsaturated fats had a beneficial effect in
slowing the development
of diabetes.
