Disease Proof

Fat is the Chief Enemy of the Diabetic

From Dr. Fuhrman’s book Fasting and Eating for Health:

Fat in the diet of the diabetic not only accelerates the disease process but also interferes with the uptake of glucose by the cells, thus further raising the blood glucose level.

Experiments described in the medical literature have tested the effects of high-fat diets on insulin intolerance. In one study, healthy young medical students were fed a very high fat diet containing egg yolks, heavy cream, and butter, and within two days all of the students had blood sugar levels high enough to be labeled diabetic.1 Complex carbohydrates have been shown to have the opposite effect.2

Fat in the food we eat prevents the proper utilization of insulin and more insulin is needed to process the glucose when fats are included in the meal. Additionally, the fat on one’s body makes the cells resistant to insulin, and the pancreas must produce more insulin to compensate. This is due not only to the additional insulin demanded by the extra body mass of fat cells, but also to the fact that the fat in and around normal tissue, like muscle and internal organs, interferes with insulin uptake into these tissues. The major contributors to fat in the American diet are animal source foods such as meat, fowl, fish, and dairy products, as well as cooking or salad oils.
