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.
Although protein digestion begins in the stomach, pancreatic enzymes break the final polypeptide chains into amino acids. The gallbladder stores secretions from the small intestine and empties them into the liver. The pancreas secretes a substance that emulsifies fat globules. The stomach secretes most of the enzymes needed for carbohydrate digestion. The digestion of food particles takes place in the small intestine, but the absorption of these digested particles takes place in the large intestine.
