Digestion is the process by which the body breaks down food into absorbable nutrients. The body absorbs and assimilates everything that we ingest. Digestion includes physical actions such as chewing and peristalsis (involuntary contraction and dilation of muscles to force forward movement), as well as the chemical actions of enzymes, bile and acids. An enzyme is a protein that acts as a catalyst in a biological reaction. It binds itself to a substance and converts it into another substance. Enzymes are very specific in their functions, which is why there are different enzymes for different biological reactions. In the case of digestion, distinct forms of food require specific enzymes. Food is digested in three areas of the body; the mouth, the stomach and the intestines. Nature's Life digestive aids and enzymes can be the answer for those who have trouble digesting foods, or those who merely want to insure optimal nutrient absorption. Remember, eat a healthy diet, chew your food thoroughly, drink plenty of water and take Nature's Life Digestive Aids for nutritional insurance.
