2. There is β -glucan in oats, which is a soluble fiber and a non-starch polysaccharide polymerized by a series of glucose molecules. This is β-glucan, which has many unique health care functions:

. Prevent colds. β -glucan can enhance the vitality of immune warriors-macrophages, quickly kill invading viruses, bacteria, fungi and other pathogenic microorganisms, and help you stay away from infectious diseases such as colds.

. Cancer prevention. β -glucan can kill sarcoma cells, melanocytes and other malignant cells, and its inhibitory rate on liver cancer and breast cancer is comparable to that of anticancer drugs, and it has no toxic side effects, so it has certain anticancer effect.

. Lower cholesterol. American experts' research shows that a patient with hyperlipidemia who ingests 3~4 grams of β -glucan every day can reduce "bad cholesterol" by 8% and reduce the risk of heart attack 10%~ 12%.

. Regulate blood sugar. The high viscosity of β -glucan can inhibit gastric emptying and delay the absorption of glucose by small intestine, thus effectively delaying the increase of postprandial blood sugar, which has certain inhibitory and preventive effects on diabetes.

. Protect the intestines. β -glucan can not be absorbed, and it can ferment in large intestine to produce short-chain fatty acids such as propionic acid and butyric acid, which can inhibit spoilage bacteria, promote probiotics, maintain the balance of intestinal flora and prevent diarrhea or constipation.

. Radiation resistance. β -glucan can promote hematopoietic function, increase the production of white blood cells and red blood cells, and reduce the harm of radiation to human body. Experiments at the Radiobiology Research Center of the US Air Force showed that mice were treated with lethal doses of radiation, and it was found that 80% of the mice were completely unaffected by radiation.
