Many people compare soy milk with milk, and according to their respective nutritional characteristics, come to "drink soy milk is better than milk", "men drink milk women drink soy milk", "children drink milk elderly drink soy milk" and the like The widely circulated conclusion, and a lot of discussion on the Internet, "Is it better to drink milk or soy milk?"

　　However, this method of comparing two different foods is theoretically wrong , Does not meet the nutritional thinking at all, and its conclusion also violates the basic principle of nutrition that diet should be diversified.

　　 In fact, as pointed out by the "Dietary Guidelines for Chinese Residents 2007": Soy milk and milk have their own nutritional characteristics, milk has better protein quality, higher calcium content, more complete nutrients, but saturated Fat and cholesterol; soy milk, protein is also good, in addition to nutrients, it also contains phytochemicals such as soybean isoflavones, saturated fat is very little, and does not contain cholesterol. Therefore, it is best to drink both ("Chinese Dietary Guidelines 2007", edited by the Chinese Nutrition Society, published by the Tibet People''s Publishing House, p. 34). This is in line with the fundamental nutritional principle of a diverse diet.

　　 Similar mistakes are "Whether milk is better or goat milk is better?" "Peanut oil or soybean oil is better?" "Rice is good or steamed buns"? These discussions are really meaningless-except for waste Spit or occupy network resources. The idea and practice of thinking that what kind of food is good and not eating when it is bad is probably equivalent to the level of first grade in nutrition.
