Diet is the most basic conditions to maintain life, but the human mess diet can induce a variety of diseases, the motherland medicine that: dietary disorders, all diseases are born. Therefore, a reasonable diet, is conducive to health, prevention and treatment of disease. So how to eat healthy, before disease prevention? First, the cause of human aging and disease – acidic waste Scientists’ research tells us that a large number of acidic food produced by acidic waste is to promote aging, resulting in endogenous diseases of the main reason, usually these acidic waste, will be excluded from the body by breathing, urine or sweat; but by the human body’s own ability to discharge acid limitations, those who have not been discharged out of the waste will be However, due to the limitations of the body’s ability to excrete acid, those wastes that have not been excreted will travel around and gradually accumulate in our body, causing the body to become acidified, and the capillaries that are full of acidic wastes to be blocked. The cellular environment gradually deteriorates, the cells therefore decline and die, which is the cause of aging, cellular aging and death lead to cellular organ function is also declining, triggering a variety of terrible endogenous diseases. Second, acidic body is the source of all diseases Cancer, cancer is the most representative of endogenous diseases, the Japanese Ai Ha’s theory of acidic body pointed out that healthy cells in the lack of oxygen in the environment, which can make the cells into cancer cells, and the acidification of body fluids just lead to a decline in the amount of dissolved oxygen, he proved the argument for the test, and won the Nobel Prize. Breast cancer is the result of acidification of body fluids. Factors such as miscarriage, breast reconstruction, refusal of breastfeeding, wearing too tight a bra, etc., result in poor local microcirculation and acidification of breast tissue fluids, the direct result of which is to cause breast tissue hyperplasia and eventually lead to cancer, and at present, at least three or more than three out of every ten women over the age of thirty-five years old in urban areas are suffering from breast cancer. The secret of cancer prevention is very simple, is to eat alkaline food to prevent the accumulation of acidic waste, because the acidified body fluid environment, is the fertile soil for normal cell cancer, adjust the acid-base balance of the body fluid, by Swiss scholars believe that the third effective way to prevent cancer. Since we cannot live without the balanced nutrition brought about by acidic foods, neutralizing acidity and alkalizing the body through the intake of alkaline foods is a wonderful solution to the problem, and doctors advocate eating less meat and more vegetables for the same reason. Vegetables contain alkaline that neutralizes acidity, so that patients with endogenous diseases who consume large amounts of vegetables with high alkaline value can obtain excellent therapeutic effects, especially for allergies, hypertension, arthritis and cancer adjuvant therapy, although alkaline food is not a drug, but the effect is enough to make us surprised. Alkaline food is food not medicine, so it does not pose any harm to the body. Third, effective measures to prevent disease 1, develop good habits, quit smoking and limit alcohol. Smoking, the World Health Organization predicted that if people are no longer smoking, 5 years later, the world’s cancer will be reduced by 1/3; secondly, do not abuse alcohol. Smoking and alcohol are extremely acidic acidic substances, long-term smoking and drinking people, very easy to lead to acidic body. 2, do not eat too much salty and spicy food, do not eat too hot, too cold, expired and spoiled food; the old and weak or those who have certain disease genes should eat some anti-cancer food and alkaline food with high alkaline content as appropriate, and maintain a good mental state. 3. Have a good mindset to cope with pressure, combine work and rest, and don’t be overworked. It can be seen that stress is an important cancer causative factor. Chinese medicine believes that stress leads to overwork and body weakness, thus causing a decline in immune function, endocrine imbalance, and metabolic disorders in the body, leading to the deposition of acidic substances in the body; stress can also lead to mental tension, causing stagnation of qi, stagnation of blood, and toxicity of internal fire. 4, strengthen physical exercise, enhance physical fitness, more exercise in the sun, more sweat.
