A diet for a healthy person that wants to remain healthy should not exceed the digestive capacity of the individual, either in terms of quantity or quality. All foods that can not be efficiently digested should be removed from the regular diet and relegated to the "sin" category, including those you are allergic to and those for which you have inadequate digestive enzymes. I have encountered very few people that can efficiently digest cooked meat, chicken, or fish, but some can, and some can with the assistance of digestive enzyme supplements. In order to digest meats, the stomach must be sufficiently acid, there must be enough pepsin, pancreatin, and bile, etc., and the meat should be eaten on the extremely rare side (not pork), in small quantities (not more than five or six ounces), and not combined with anything except nonstarchy vegetables. If you must include meat in your dietary, it should represent a very small percentage of your total caloric intake, be eaten infrequently, with the bulk of the calories coming from complex carbohydrates such grains, legumes and nuts, as well as large quantities of vegetables and fruits. The healthy person that wants to stay that way for many, years is advised to fast one day a week, to give the organs of elimination a chance to catch up on their internal housecleaning. If water fasting seems impossible, try a day of juicing it; if that is too rigorous, try a day on raw foods. A similar technique, though less beneficial than even a one day each week on raw foods, is delaying breaking your overnight fast for as long as possible each day. Try giving up breakfast altogether or postponing breaking your overnight fast, because from the time you stop eating at the end of one day to the time you start eating the next is actually a brief, detoxifying fast. Eggs, milk, cheese and yogurt can be assimilated by some healthy people with or without digestive aids. It is possible to take lactase to break down the milk sugars for example; sometimes aids such as hydrochloric acid, pepsin, and pancreatin help. If you can buy it or are willing to make it raw milk yogurt containing lactobacillus bulgaris or acidophilus may be digested more readily, especially if it prepared from healthy cows or goats fed on unsprayed food, and served very fresh. Eggs should come from chickens that run around outside, eating weeds, and scratching bugs. The yokes of those eggs will be intense orange, not yellow. Few people these days have ever eaten a real egg. Surprisingly, for those of you who fear cholesterol, the healthy way to eat eggs is use just the raw yolk from fertile eggs. It is enjoyed by many people in a smoothie--fresh fruit blended up with water or milk. Eggs contain lecithin, a nutrient that naturally prevents the body from forming harmful fatty deposits in the arteries.
