Nationally renowned health education expert Professor Hong Zhaoguang in his “let health with you” lecture to promote the drinking of milk to a high amazing position – a bag of milk to revitalize a nation. Milk has the effect of increasing the height and moisturizing the skin, strengthening the body and the bones, and improving the intelligence and beauty, and it can prevent and control stroke, high blood pressure and heart disease. Teenagers who drink a bag of milk since childhood average height increase of 2.8cm, drink two bags of the average height increase of 4.8cm, Japan after World War II because of the whole nation strongly advocate drinking milk, the height of the general increase in height, and took off the hat of small Japan. Milk is not expensive, the market supply is sufficient, such a miracle, do not drink it is not a fool! However, another famous health education experts, Professor Qi Guoli on these miraculous effects of milk seems to have turned a deaf ear to the advocacy of the whole nation to drink milk a little disdain, pointing out that its nutritional value is not as good as soymilk, and quite defective, to engage in a little compromise, not opposed to drinking milk, but advocate drinking more soymilk. Recently, the national reputation, circulation of the “Discover” magazine, the 5th issue of the article contained in the Westwood, listed a large number of scientific evidence, counting the disadvantages of milk, flagrantly opposed to the advocacy of wide drinking milk, and advocate drinking soybean milk. (1) milk contains lactose, need to rely on the lactase enzyme decomposition and absorption, more than two-thirds of the Asian people lack lactase, more than 80% of the people in the country, the lack of lactase enzyme can not digest lactose, but also can not effectively absorb the calcium in milk, undigested lactose accumulated in the intestinal tract, will be fermented and produces gas, resulting in bloating, diarrhea; (2) milk contains calcium, although not less than the magnesium content of magnesium is low, calcium and magnesium are usually required to co-occur The role of calcium and magnesium usually need to occur together (2:1), in order to increase absorption, to maintain balance, maintenance of heart and brain health, the ratio of imbalance affects the absorption of calcium and the role of play; (3) milk does not have in other plants and animals can not be found in the nutrients; (4) milk is the human body’s No. 1 food allergens, childhood diabetes and milk allergy related to the serum albumin; (5) drink soybean milk drink milk more suitable for the country’s long-term diet; (6) the calcium and magnesium content of soybeans in both calcium and magnesium, can cause diarrhea, diarrhea, and abdominal distension. Soybean calcium and magnesium content are rich, than the appropriate portion, so drink soy milk calcium net absorption rate is higher than drinking milk; (7) soybean oligosaccharide is intestinal bacillus (bifidobacteria) food, soybeans are rich in high-quality proteins, lecithin, isobarbital, as well as a variety of vitamins and minerals; (8) in 2001, the U.S. Food and Drug Administration (FDA) organization of the ten best food selection, soybeans took the title, and became the crown of food, nutritional flowers. Become the crown of food, nutritional flowers. Scientific arguments are strong, soy milk can be called the ideal drink, where milk can be reached! Both are famous experts and scholars, one side for the social research arguments, one side for the scientific experimental arguments, but the conclusions are very different. Which is right and which is wrong? Who to listen to? Who to believe? Drink what? I am afraid that they are biased! Existence must have its rationality, everything is divided into two, some short, some long, no everyone is suitable for perfect food. Men and women, young and old, fat and thin, tall and short, poor and rich, south and north, ten fingers are not all the same, each take what they need, each good. People who lack the enzyme lactase naturally should not drink milk, while others can drink it without harm. A bag of milk may not be able to revitalize a nation, but pay attention to the surrounding population, often drink milk is good for health, especially the elderly. 80% of the country drink milk on diarrhea, the figures always feel exaggerated. Soymilk, although inexpensive and delicious, but there are many people feel uncomfortable, strong drink may not be beneficial to the appetite and health. All advocate drinking yogurt, but it can only be cold, can not be cooked hot, so the elderly, winter and cold stomach should not be, and many people just do not like the sour taste, it is difficult to force. In short, milk or yogurt, soy milk, too, are appropriate for different people, long-term drinking, complement each other. Popularization of science workers, should be highly responsible attitude towards the general public, factual preaching, can not be eaten alive, copying others, generalization, thick and thin, so that the Chinese people’s diet to become a Handan learning.
