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 Begins. Enzymatic digestion occurs primarily in the mouth, stomach and small intestine. Both physical and chemical digestion begin in the mouth: the process of chewing grinds up food and mixes it with saliva, which contains an enzyme called salivary amylase. Enzymes facilitate chemical reactions by binding to reactive molecules.
