Steps to a Healthier Digestive System Elimination diets are a good method of determining what foods cause allergy or an irritation of the GIT lining in a patient constipation-parasites Planning and following such diets are a safe starting point for anyone desiring to track their GIT response to food constipation-parasites Interview Interview physicians to learn who may be most qualified to assist in planning an elimination diet constipation-parasites A very good indicator of a healthy GIT is a regular transit time for complete food digestion constipation-parasites Patients who are regular are usually in optimum health constipation-parasites Aging causes many people to experience experience problems with digestion constipation-parasites It is estimated that after age 40 there is an approximate decrease in the body's ability to produce enzymes by 20 to 30% constipation-parasites This can be helped by the use of specific enzymes to improve the efficiency of digestion constipation-parasites Enzymes can be used to to enhance the proper breakdown of foods in order to more properly digest, absorb, and utilize nutrients constipation-parasites Enzymes Are a Vital Component of the Digestive Process Enzymes are essential to the body's absorption and full use of food constipation-parasites The capacity of the living organism to make enzymes diminishes with with age, and some scientists believe that humans could live longer and be healthier by guarding against the loss of our precious enzymes constipation-parasites Enzymes are responsible for every activity of life constipation-parasites Even thinking requires enzyme activity constipation-parasites There are two primary classes of enzymes responsible for maintaining life functions: functions: digestive and metabolic constipation-parasites The primary digestive enzymes are proteases (to digest proteins) , amylases (to digest carbohydrates) , and lipases (to digest fats) constipation-parasites These enzymes function as a biological catalyst to help break down food constipation-parasites Raw foods also provide enzymes that naturally break down food for for proper absorption constipation-parasites Metabolic enzymes are responsible for the structuring, repair, and remodeling of every cell, and the body is under a great daily burden to supply sufficient enzymes for optimal health constipation-parasites Metabolic enzymes operate in every cell, every organ, and every tissue and they need constant replenishment constipation-parasites Digestion of food takes a high priority and has a high demand for enzymes constipation-parasites When we eat, enzymatic activity begins in the mouth, where salivary amylase, lingual lipase, and ptyalin initiate starch and fat digestion constipation-parasites In the stomach, hydrochloric acid activates pepsinogen to pepsin, which breaks down protein, protein, and gastric lipase begins the hydrolysis of fats constipation-parasites Without proper enzyme production, the body has a difficult time digesting food, often resulting in a variety of chronic disorders constipation-parasites Poor eating habits, including inadequate chewing and eating on the run, may result in inadequate enzyme production and hence malabsorption malabsorption of food which is exacerbated by aging because this is a time of decreased hydrochloric acid production as well as a general decline in digestive enzyme secretion constipation-parasites Saliva is rich in amylase, while gastric juice contains protease constipation-parasites The pancreas secretes digestive juices containing high concentrations of amylase and and protease as well as a smaller concentration of lipase constipation-parasites It also secretes a small concentration of maltase, which reduces to dextrose constipation-parasites Animals eating raw food often have no enzymes at all in saliva, unlike humans constipation-parasites However, dogs fed a high carbohydrate, heat-treated diet have been found to to develop enzymes in their saliva within a week in response to enzyme-depleting foods constipation-parasites One of America's pioneering biochemists and nutrition researchers, Dr constipation-parasites Edward Howell (1986) , cites numerous animal studies showing that animals fed diets that are deficient in enzymes have enlargement of the pancreas, as huge amounts |
