Actually, borderline diabetes is a somewhat misleading term. The term pre-diabetes, which is more widely used today, better describes what is happening. Pre-diabetes means that your blood glucose is higher than normal but not yet high enough to be considered diabetes.
Fat digestion also begins in the mouth with the secretion of the enzyme lingual lipase by glands under your tongue. Although this enzyme doesn't do much with the food while it's in your mouth, it does move on down with the food to your stomach, where it can start to break down about 10-30% of the food's fat content.
Digestion Part 2: Your Small Intestine. Most fat digestion happens once your food passes from the stomach to the small intestine. In the upper part of the small intestine, the duodenum, mechanical emulsification continues with the help of bile acids released from the gall bladder, where they are stored after being produced by the liver.
