You can eat black beans when you are pregnant, but you should pay attention to moderation. During pregnancy, pregnant women have a greater demand for nutrients in order to meet the nutritional needs of the mother’s own body and the growth and development needs of the fetus. Black beans are rich in protein and a variety of trace elements, minerals and other nutrients, can be supplemented for pregnant women. It should be noted that pregnant women with relatively poor gastrointestinal function, intestinal peristalsis slower, less tension, high protein content in black beans, excessive consumption of black beans may cause bloating, indigestion and other adverse consequences, so pregnant women should consume black beans in moderation. If necessary, pregnant women can also consult the relevant professional physicians and dietitians before eating, so as to avoid improper diet, resulting in adverse consequences.
