It is not recommended for pregnant women to eat pickled food, because the pickled food for a long time may contain a certain amount of nitrite, which will be converted into ammonium nitrate through digestion and metabolism of digestive juice after entering the human body. Ammonium nitrate itself is a carcinogen, which may have adverse effects on fetal development, so it is not recommended to eat.
Vegetables that pregnant women can't eat mainly have the function of promoting blood circulation and removing blood stasis, because after pregnancy, they can't break blood and gas, otherwise it will easily lead to abortion. Therefore, as foods with the effect of promoting blood circulation and removing blood stasis, foods and drugs that are usually used to promote blood circulation and remove blood stasis and reduce swelling are not suitable for eating in this physiological period, as well as some foods that are hot and cold, and some foods that are allergic at ordinary times.
