1. People with anemia should not eat too much dietary fiber. If you eat more than 50g of fiber every day, it may reduce the utilization rate of protein and affect mineral absorption. Coarse grains are rich in dietary fiber.

2. Secondly, cereals such as oats, buckwheat, corn and miscellaneous beans such as mung beans and red beans also contain "anti-nutritional" phytic acid and other substances. They will hinder the absorption of minerals such as calcium, iron and zinc, and also delay the digestion and absorption of protein. These will affect the health of anemia to some extent.
