Vegetables contain many nutrients, such as macroelements, microelements, vitamins, cellulose and so on, which are difficult for human beings to obtain from grains and meat. People all know that eating vegetables often is good for health, but they don't necessarily know that vegetables are divided into cold and hot, so it is impossible to choose vegetables according to their own physique. Chinese medicine believes that vegetables have different tastes and functions, and many vegetables are cold, so there is a saying that vegetables can clear heat and dispel fire.
