Lotus root is abundant in southern China. Lotus root contains water, protein, soup, fat, calcium, iron, vitamins, trace elements and other nutrients. Pregnant women can eat lotus root to supplement pregnancy nutrition and help correct anemia during pregnancy. Under the action of hormones during pregnancy, gastrointestinal peristalsis slows down, which is easy to cause constipation, while lotus root contains more cellulose, which can improve the symptoms of constipation during pregnancy. Lotus root can be made by frying, cold salad, soup and other cooking methods, but it can't be too spicy to avoid irritation. Pregnant women who like to eat lotus root before pregnancy can also eat it during pregnancy to increase their appetite. But it is not advisable to eat more. At the same time, fresh lotus root should be chosen to avoid gastrointestinal discomfort, uterine contraction and poor outcome.
