Brown rice is the caryopsis after the rice is removed from the outer protective cortex, and the inner protective cortex (peel, seed coat, bead layer) is intact. The grain is thicker due to the inner protective layer of crude fiber and wax. Tight, it takes a lot of time to cook, but its slimming effect is remarkable. Compared with ordinary refined white rice, brown rice is richer in vitamins, minerals, and dietary fiber, and is considered a green and healthy food.
60%-70% of the vitamins, minerals and essential amino acids in rice are accumulated in the outer layer. The delicate white rice we usually eat is white and delicate, and the nutritional value has been lost in the process, plus cooking. When it is washed repeatedly, the outer layer of vitamins and minerals are further lost. The rest are mainly carbohydrates and some proteins, and its nutritional value is much lower than that of brown rice. Studies have shown that the content of calcium in brown rice is 1.7 times that of white rice, the iron content is 2.75 times, the nicotinic acid is 3.2 times, and the vitamin B1 is up to 12 times. Vitamin E in brown rice is 10 times that of white rice and cellulose is 14 times higher. Compared with whole wheat, the protein content of brown rice is not much, but the protein quality is better mainly rice sperm protein. The composition of the amino acid is relatively complete, the human body is easy to digest and absorb, but the content of lysine is less, and it contains more fat. And carbohydrates can provide a lot of heat to the body in a short time.
Modern nutrition research has found that vitamin B and vitamin E in rice bran and germ part of brown rice can improve human immune function, promote blood circulation, and help people to eliminate depression and irritability and make people energetic. In addition, trace elements such as potassium, magnesium, zinc, iron, and manganese in brown rice are beneficial for preventing cardiovascular diseases and anemia. It also retains a large amount of dietary fiber, which can promote the proliferation of beneficial bacteria in the intestine, accelerate intestinal peristalsis, soften stools, prevent constipation and intestinal cancer; dietary fiber can also combine with cholesterol in bile to promote cholesterol excretion, thereby helping hyperlipemia The patient lowers blood lipids.
