As we all know, soy products contain more high-quality protein, calcium and vitamins, but less fat and mainly unsaturated fatty acids, without cholesterol, and high nutritional value; soy also contains soy isoflavones, lecithin, oligomeric Sugar, saponins and other special ingredients with health care effects are beneficial to the prevention and treatment of modern diseases such as hyperlipidemia, hypertension, arteriosclerosis, fatty liver, and tumors. Therefore, they are widely recommended worldwide. The Chinese Nutrition Society has several versions of dietary guidelines Both recommend soybeans and their products. The 2007 edition of the "Dietary Guidelines for Chinese Residents" recommended that each person consume 30 to 50 grams of soybeans or equivalent soybean products per day. Converting this figure into soy milk, tofu or tofu skin (or dried tofu) is roughly 600 ml to 1000 ml, 130 g to 220 g, and 65 g to 110 g.

　　However, it should be pointed out that soybeans and their products are mainly soybeans, black beans and green beans, and generally do not include mung beans, red beans, peas, fava beans, kidney beans and other miscellaneous beans. The nutritional composition of mixed beans and soybeans is very different. The protein content of mixed beans is not as high as soybeans, and the amino acid composition is not as reasonable as soybeans. It is not a high-quality protein; mixed beans also do not contain beneficial ingredients such as isoflavones, and their nutrition The characteristics are closer to grain than soybean. Therefore, at the press conference of the New Dietary Guidelines held by the Ministry of Health on January 15, 2008, Professor Ge Keyou, the current chairman of the Chinese Nutrition Society, emphasized: "There is a difference between mixed beans and soybeans... In order to fully obtain soybeans to the Chinese people The health benefits of this time, we emphasized soybeans this time, and put miscellaneous beans into miscellaneous grains. Don’t think that eating only beans, green beans and red beans may not work as well, and eating more soybeans is more guaranteed ".

　　All the time, people mistakenly recommend or eat mung beans, red beans, peas and other miscellaneous beans as soy products, which has buried the important value of soybeans (mainly soybeans) to some extent. This error may originate from the fact that there are not many types of beans in developed countries, mainly soybeans (soy or soy) bean), when it comes to beans, basically talking about soybeans, this habit is copied to the country (unsurprisingly, the foundation of modern nutrition is established in developed countries and introduced into the country), do not know the Chinese diet There are many kinds of beans.

　　 Of course, the nutrition of miscellaneous beans is also good, and can be recommended as food, but it must be clear that miscellaneous beans cannot be recommended as soy products (soy products), and their nutritional characteristics are not the same as soybeans. .
