When food is consumed uncooked, fewer digestive enzymes are required to perform the digestive function bad-breath-atkins-diet-bad-breath The body will adapt to the plentiful, external supply by secreting fewer of its own enzymes, preserving them to assist in vital cellular metabolic functions bad-breath-atkins-diet-bad-breath One of the worst cooking methods is frying, since since frying results in much higher temperatures than boiling bad-breath-atkins-diet-bad-breath Frying damages protein as well as destroying enzymes bad-breath-atkins-diet-bad-breath Enzymes can also be wasted by lifestyle factors bad-breath-atkins-diet-bad-breath Enzymes work harder with increasing temperatures and are used up faster bad-breath-atkins-diet-bad-breath A fever, for example, induces faster enzyme action and is therefore therefore unfavorable for bacterial activity bad-breath-atkins-diet-bad-breath Enzymes can be found in urine after a fever, and also may be found after strenuous athletic activity bad-breath-atkins-diet-bad-breath A natural behavior of animals is to harness the power of enzymes in food by burying or covering their food, allowing enzyme activity to start predigesting predigesting the food bad-breath-atkins-diet-bad-breath By this natural behavior, animals instinctively preserve their own enzyme supply bad-breath-atkins-diet-bad-breath Similarly, people of some native cultures also preserve their enzyme supply and disease prevention through efficient use of enzymes bad-breath-atkins-diet-bad-breath Whales have up to 6 inches of fat to keep them warm, but their arteries arteries are not clogged bad-breath-atkins-diet-bad-breath Eskimos, who frequently consume large quantities of fat, are often not obese bad-breath-atkins-diet-bad-breath Both of these groups eat the fat-digesting enzyme lipase in the form of raw foods bad-breath-atkins-diet-bad-breath Studies (both in vitro and controlled in vivo) using internal and parenteral routes have examined the effectiveness effectiveness of may different types and sources of plant enzymes in a several conditions, including poor digestion, poor absorption, pancreatic insufficiency, steatorrhea, lactose intolerance, celiac disease, obstruction of arteries, and thrombotic disease bad-breath-atkins-diet-bad-breath Enzymes from the Aspergillus oryzae fungus were subjected to numerous studies evaluating their role in supporting healthy digestion bad-breath-atkins-diet-bad-breath digestion bad-breath-atkins-diet-bad-breath Additionally, human studies suggest the proteolytic enzymes derived from Aspergilus oryzae fungus may play a role in anti-inflammatory and fibrinolytic therapies bad-breath-atkins-diet-bad-breath The enzymes appear to be relatively heat stable, and they are also active throughout a wide pH range bad-breath-atkins-diet-bad-breath This is important because most enzymes are deactivated deactivated in stomach acid bad-breath-atkins-diet-bad-breath These enzymes are synthesized from fungus, but contain no fungal residue even though that is their derivation bad-breath-atkins-diet-bad-breath Modern filtration techniques and technology enable these fungal enzymes to be well suited for human consumption bad-breath-atkins-diet-bad-breath According to Dr bad-breath-atkins-diet-bad-breath Mark Percival (1985) , oral supplementation of of digestive enzymes taken just before or at mealtime can assist digestion bad-breath-atkins-diet-bad-breath Even though most supplemental enzymes are labile and will deactivate when exposed to stomach acid, Dr bad-breath-atkins-diet-bad-breath Percival believes some of the enzymes will remain active if they are taken with a meal or just before bad-breath-atkins-diet-bad-breath Percival Percival says, The enzymes are physically protected by the meal and allow some enzymatic activity to occur in the stomach bad-breath-atkins-diet-bad-breath The enzymes that get through to the small intestine may help with digestion there as well bad-breath-atkins-diet-bad-breath pH plays a major role in enzymatic activity, therefore, the enzymes derived from from Aspergillus may be highly useful as they appear to be remarkably stable, even when subjected to an acidic environment bad-breath-atkins-diet-bad-breath Additionally, Dr bad-breath-atkins-diet-bad-breath Edward Howell (1986) adds that he chews an enzyme capsule with his food in order to start the digestive process as soon as the food is consumed |
