Brown rice refers to the whole grain except the hull. That is, rice containing cortex, aleurone layer and germ.

The correlation is as follows

First, the role of diet therapy.

(1) Brown rice has the effects of improving human immune function, promoting blood circulation, eliminating depression and irritability, and preventing cardiovascular diseases, anemia, constipation and intestinal cancer.

(2) The nutrition of brown rice is far superior to that of refined white rice. For example, the calcium content in brown rice is 1.7 times that of white rice, the iron content is 2.75 times, the nicotine content is 3.2 times, and the vitamin B 1 gundam 12 times that of white rice. The vitamin E in brown rice is 10 times that of white rice.

Second, the characteristics

(1) Brown rice belongs to caryopsis with smooth and shiny surface. In brown rice, the embryo-bearing side of the rice is called belly white, and the embryo-free side is called back. There are five longitudinal grooves on the surface of brown rice grains, one on the back is called back groove, and two on both sides are called rice grooves.

(2) It is difficult to completely remove the cortex at the furrow of brown rice during rice milling. For the same variety of rice, the more skin left at the furrow, the lower the processing accuracy, so the processing accuracy of rice is often expressed by the degree of skin left on the grain surface and back furrow.

(3) The depth of longitudinal furrow varies with different rice varieties, which has certain influence on rice yield. Some brown rice shows opaque white spots in the abdomen or the center of rice grains, which is abdominal white or heart white.

(4) White belly and white heart are caused by unsuitable climate, rainfall and fertilizer during rice growth.

Third, the effect

(1) Vitamins B and E in the rice bran and germ of brown rice can improve human immune function, promote blood circulation, and help people to get rid of depression and irritability, making people full of vitality.

(2) In addition, trace elements such as potassium, magnesium, zinc, iron and manganese in brown rice are beneficial to prevent cardiovascular diseases and anemia. It also retains a large amount of dietary fiber, which can promote the proliferation of intestinal beneficial bacteria, accelerate intestinal peristalsis, soften feces, and prevent constipation and intestinal cancer.

(3) Dietary fiber can also combine with cholesterol in bile to promote the discharge of cholesterol, thus helping patients with hyperlipidemia to lower their blood lipids. Eating brown rice is especially beneficial for diabetics and obese people. Because the carbohydrates in it are wrapped by crude fiber tissue.

(4) The human body has a slow digestion and absorption speed, so it can control blood sugar well; At the same time, trace elements such as zinc, chromium, manganese and vanadium in brown rice are beneficial to improve the sensitivity of insulin and help people with impaired glucose tolerance.
