If emaciated people have no organic diseases, emaciation is mostly caused by unbalanced food nutrition or excessive diet control. Lack of nutrition is nothing more than protein, fat, carbohydrates, vitamins and so on. The main way to improve it is to adjust the previous diet structure reasonably, so that plant protein and animal protein can be reasonably matched; Reasonable collocation of saturated fatty acids and unsaturated fatty acids; Reasonable collocation of low-calorie and high-calorie carbohydrates; Reasonable collocation of fat-soluble and water-soluble vitamins. Generally speaking, you can't eat too much or too little food, that is, you can't be partial to food. On the issue of tonic, as the saying goes, medicine tonic is better than food tonic. Here we recommend several tonics with the same origin of medicine and food: honey, tremella, jujube, yam, longan meat, walnut kernel and so on. In addition, it is also a good choice to take Buzhong Yiqi Pills. Some humble opinions are for reference only. If you get benefits, you won't live up to my expectations.
