I was recently reading a post about a study on fats and diabetes. Here are some exerts from the article.
Exchanging either carbohydrates or saturated fats for unsaturated
fats, especially poly-unsaturated fats, was linked to improved blood
glucose levels, insulin resistance, and insulin secretion.
Increasing unsaturated fat
intake (mono- or poly-unsaturated) improved three month average glucose
levels found in a person’s blood by 0.1%. A 0.1% improvement could reduce the incidence of diabetes by 22%,
which is deem as clinically meaningful especially given the
current global pandemic of diabetes.
This is great news, because foods that contain fat are filling and satisfying. Polyunsaturated fats are found in plant based oils such as sunflower and soybean. Nuts and seed and fatty fish are excellent sources of polyunsaturated fats. Monounsaturated fats are found in olives and avocados. Of course the oils from these foods are also good choices.
Read the label on your oil, do not just choose vegetable oil, upgrade to one with more polyunsaturated fat. Avoid using shortening and lard as these are mostly saturated fat and also contribute to cholesterol build up.
