Disadvantages:
(1) Steamed bread is a finely processed food. The finer and whiter the food is processed, the more nutrients are lost. White rice flour contains almost no dietary fiber, which will be quickly digested and absorbed, and will suddenly increase insulin secretion after meals, aggravating insulin resistance. Long-term consumption of refined food will lead to insufficient intake of vitamins, lysine and minerals. , leading to vitamin deficiency (such as vitamin B deficiency, beriberi) and even anemia.
(2) White steamed bread bought in the market is not necessarily the best choice for taste and physical and mental health. Now unscrupulous businessmen will add some whitening agents when making steamed bread. For example, a fluorescent whitening agent called sodium formaldehyde sulfoxylate is a compound that can bleach, prevent corrosion and toughen, and has a strong carcinogenic effect.
Grain rice
(3) Long-term use of steamed bread as a staple food and a single staple food will weaken the adaptability of the digestive system, and the growth of flora in the digestive system will be unbalanced. When eating other foods, the gastrointestinal burden will be heavier and indigestion will be easy.
Therefore, it is best not to have a single staple food and eat more coarse grains.
