Food and drink are necessary to nurture life. But if it’s not known , the natures of the various substances can be opposed to each other, and are consumed together indiscriminately, the vital organs lose their harmony and soon there are disastrous consequences. “There are four basic foundations to achieve and maintain good health,” These are: diet, exercise, adequate rest and relaxation, and a good mental attitude. “According to this perspective a correct and harmonious diet not only influence our health but also in more subtle aspects such as our conscience based on the Yin-Yang principles of each food and in its contribution of “QI” the fuel of life. We should eat seasonally, our bodies are rhythmic and in touch with natural cycles. “QI” is found in abundance in fruit and vegetables matured in the sun, in plants grown without artificial fertilizers, in animals and products of animal origin from livestock adapted to the specific species and in the water from natural springs. “QI” is widely preserved when foods are prepared fresh, eaten raw, carefully cooked or lightly fried. “QI” is severely reduced or disappears when foods are canned, frozen, bake for a long time, heated in the microwave or fried a lot. Most of us possess a balanced metabolism capable of admitting various kinds of food when properly combined. Although our digestive tract was originally designed by nature for a diet of fruits and vegetables, our digestive system has evolved and is capable of producing the gastric juices necessary to digest the meat that became part of the human diet. If large amounts of animal protein do not leave you exhausted, and if large doses of sugars and starches do not make you feel nervous, you are likely to have a balanced metabolism that only needs to worry about choosing healthy foods from both categories and to combine them correctly.
