Tricolor brown rice can be consumed by pregnant women in moderation, but not in excess to avoid bloating, indigestion and other discomforts. Tricolor brown rice is mainly from brown rice, red brown rice, black rice and other three types of rice mixed, which contains a lot of nutrients and has a very high nutritional value, such as protein, amino acids, vitamins, inorganic salts. The dietary fiber and amino acids contained therein can be beneficial to defecation and urination after moderate consumption. Secondly, due to the large amount of insoluble fiber in brown rice, it may cause indigestion and increase the burden on the gastrointestinal tract after consumption. Therefore, pregnant women with poor gastrointestinal function should not consume it to avoid aggravating their discomfort. Pregnant women should pay attention to rest in their daily life and attend pregnancy tests regularly. After any uncomfortable symptoms, they should consult a doctor immediately.
