精米的健康隐患：从营养角度看精米加工的危害

For a long time, people have been accustomed to consuming 'polished rice' made from rice grains in pursuit of better taste. Numerous research results at home and abroad have shown that 'polished rice' and white flour have become a major threat to people's health worldwide. In addition, about 20% of the rice bran components (including rice husks, seed coats, starch layers, embryos, etc.) are removed during the processing of rice grains into 'polished rice', while a large amount of broken rice is generated, causing enormous waste. 'Polished rice', after processing, mainly consists of starch and a small amount of protein, with limited nutritional value. The removed rice bran components are rich in protein, dietary fiber, unsaturated fatty acids, vitamins, minerals, flavonoids, and various nutrients, as well as active ingredients such as grain fiber and γ-aminobutyric acid.
