Pregnant women can eat prunes, which are rich in nutrients and have a very high content of vitamin A, which is beneficial to the development of fetal vision. The minerals in prunes, such as potassium, are good for regulating the electrolyte balance and the function of the nervous system in the body. Iron is essential for the production of red blood cells and can prevent physiological anemia during pregnancy. The citric acid, succinic acid and malic acid in prunes have certain antihypertensive effects and are more suitable for women with mildly increased blood pressure during pregnancy. The dietary fiber in prunes can prevent constipation during pregnancy, although prunes are good, high blood sugar or frequent diarrhea during pregnancy is best not to eat prunes. Because the sugar content in prunes is very high, it is easy to increase the burden on the pancreas and aggravate the symptoms of high blood sugar. Prunes are a cold food, which can easily aggravate diarrhea and cause gastrointestinal disorders.
