What is the origin of oat bran, the latest popular super food in America?
Oat bran contains the most abundant β -glucan in cereals. β -glucan is a soluble dietary fiber, which is a known effective component for reducing blood lipid, so oat fiber is known as "aristocratic dietary fiber".

1. Water-soluble dietary fiber: Only oats and barley in natural grains contain water-soluble dietary fiber, especially oat water-soluble dietary fiber β-glucan. Water-soluble dietary fiber (soluble dietary fiber) can absorb a lot of cholesterol in the body and excrete it, thus reducing the cholesterol content in the blood. /kloc-more than 0/000 papers reported the functions of oat β -glucan in regulating blood sugar and blood lipid, softening blood vessels, preventing hypertension, enhancing immunity, preventing cardiovascular and cerebrovascular diseases, resisting skin allergy and controlling weight. β -glucan is mainly concentrated in embryonic cell wall and aleurone layer, and is connected by β-( 1-3) and (1-4) glycosidic bonds, forming a tough, complex and relatively inert cell wall, which plays a skeleton role in supporting and protecting biological cells and bioactive substances in cells. This proves that the bran layer is the place where nutrition really gathers! Wheat and rice are almost the same, so you can imagine how wasteful human beings are. Therefore, oat bran, as a common food with important health care function, has been widely promoted in the United States and Germany.

2. Insoluble dietary fiber: oat bran also contains a lot of insoluble dietary fiber, which is helpful for digestion and can prevent constipation in children. Like a brush, brush off the dirt on the intestinal wall and excrete it with stool.

Soluble dietary fiber, like a sponge, absorbs the garbage in the body and excretes it with metabolism; Insoluble dietary fiber is like a brush, which brushes off the dirt on the intestinal wall and excretes it with the stool. Therefore, it has a good conditioning effect on constipation or irregular stool. More importantly, it can help the body detoxify, keep the whole body clean and refreshing, and also have an auxiliary conditioning effect on skin and blood circulation problems.

3. Oat Firming Protein: Oat Firming Protein is a unique ingredient of oat bran, which has an instant firming effect, can make the skin instantly firming, has a synergistic effect on moisturizing, film forming and smoothness, and also has an anti-aging effect. The molecular weight distribution of oat coagulation protein was determined by HPLC. The results showed that oat coagulation protein was composed of protein with molecular weight above 5000. The molecular weight of these proteins is mostly consistent with the molecular weight range of albumin, indicating that oat compact protein is composed of unhydrolyzed and partially hydrolyzed oat protein.
