The principle of eating leftovers is "Leave no leftovers, don''t leave cold dishes." Why can''t this vegetable be left? Director Wang said that the vegetable already contains nitrate. When the rest is stored in the refrigerator, the storage time is a little longer, and the nitrate will be converted into nitrite, a small amount of nitrite Salt is not particularly terrible, but if you eat leftovers for a long time, nitrite will convert nitrosamines, which has a carcinogenic effect. Therefore, the remaining vegetables, especially the long time left, must not be eaten.
