The nutritious meal consists of brown rice flour, cereal, malt extract, corn, soybean, coix seed, lotus seed, spirulina, etc. After hulling of brown rice, the inner layer is chaff layer, accounting for about 5% of rice, which is mainly composed of protein and vitamins. The white fat part is endosperm, accounting for about 92% of the rice volume, and the main component is starch; The top of rice is germ, which accounts for about 3% of the grain. It is rich in B vitamins and vitamin E, and also contains a lot of protein, fat, carbohydrates and various minerals. The nutrients in each part account for 90% of the whole rice, 20% of the bran layer and 10% of the endosperm. The brown rice in the nutritious meal retains the husk, endosperm and germ, and retains most of the nutrients. This is different from the refined white rice and refined white flour we usually eat. Polished white rice and polished white flour have removed the husk and germ rich in protein, minerals and vitamins (all the rice we see has a gap at the top, and the missing part is the germ), leaving only the endosperm with little nutrition.
