But many water-soluble nutrients unstable, its decomposition temperature is too high will lead to destruction of water-soluble vitamins and minerals dissolved in the soup may be more, but a lot of soup cooking oil, eating can lead to obesity , do not eat soup, these nutrients lost. Some multi-fuel cooking, Hong, is one of the reasons is the high boiling point of oil, up to 300 ℃ or higher, can some of the material comes out of the low boiling point have flavor, but increased the destruction of beneficial ingredients.

These nutrients, mainly from fresh vegetables, fruits, and improper cooking will result in the loss of nutrients, so the promotion of eating raw fruits and vegetables such as apples, grapes, tomatoes, cucumber, etc., but there is microbial contamination problem, especially in some temperature, high humidity areas, breeding of pathogenic microorganisms and easy.
