Community PageI'm reading this blog for the first time and I see a great deal of misinformation. Perhaps I can clear up some of it to enhance better understanding of human anatomy and physiology. Sorry if I step on toes but please be objective. None of what I wrote is to be taken as a personal attack.
@Freshy: Digestion doesn't take place in the stomach and it has more than two sections -- there are the cardiac region, the fundus, the body and the atrium.
@Socal: Overweight is NOT always a sign of poor health. BMI is no indicator of lean muscle mass to fat ratio and thin people (e.g. cachexia) can be very ill. Raw diets don't reverse "many diseases", however a balanced raw diet may help prevent some.
@Zoe: Enzymes are proteins and function as organic catalysts. They ARE organic molecules. The four most important classes of organic molecules are lipids, carbs, nucleic acids and proteins!
@germin8: You're right that "the mouth" doesn't absorb enzymes but the mouth doesn't secrete them either. The process of digestion begins in the mouth during mastication (chewing). Saliva is the key. Saliva is produced and secreted by salivary glands -- the sublinguals, the submandibulars and the parotids.The major enzymes in saliva are alpha amylase, salivary kallikrein, salivary lipase and lysozyme. Although a very few substances, such as alcohol and water, are absorbed from the stomach into the blood, digestion doesn't take place there. The bulk of digestion takes place in the three sections of the small intestine, not the "lower intestines", which I interpret to mean the large intestine. By far, most ingested enzymes are broken down, not utilized as is. Enzymes are complex proteins that fall into 3 main categories: metabolic, food and digestive. Most digestive enzymes are synthesized in the pancreas, not the intestines. The other organs accessory to the GI tract -- liver and gallbladder -- also contribute to the process. With the exception of pineapple & papaya, raw food contains only enough enzyme to digest that particular food. Not enough to be stored for later use.
