Black rice, also known as the custom of sorghum smut, has high nutritional value. Sorghum black rice is caused by sorghum head smut, which belongs to basidiomycetes. Sorghum black rice has high nutritional and medicinal value, which is rich in protein, carbohydrates, minerals, vitamins and other nutrients.

Especially, eight kinds of essential amino acids, active polysaccharides such as fungal polysaccharides and dietary fiber, and minerals such as potassium, iron, selenium, vitamins A, B 1, B2, B6 and C are high in content, so it is an ideal natural health food. The United States has listed it as an edible fungus, and Mexico also regards it as a good food, but its development and utilization in China is still blank.

2. Corn

The nutritional components of corn are comprehensive, generally containing 8.5% protein, 4.3% fat, 73.2% sugar, 0.022% calcium, 0.2 1% phosphorus and 0.00 16% iron, as well as carotene, vitamin B 1, B2. , vitamin e, lysine, etc. The latest research points out that corn contains an anticancer factor-glutathione.

Nutritionists at home and abroad give high evaluation to corn, and think that glutathione contained in corn has anticancer effect, which can combine with many carcinogens in human body and make these substances lose carcinogenicity.

Cellulose contained in corn is a kind of carbohydrate that is not absorbed by human body, which can reduce the concentration of carcinogens in human intestine, reduce the accumulation of humic substances secreting toxins in intestine, and thus reduce the incidence of colon cancer and rectal cancer.

Lignin contained in corn can increase the activity of "macrophages" in human body by 2~3 times, thus inhibiting the occurrence of cancer; Corn also contains a lot of minerals, and magnesium in food has obvious anti-cancer effect. Japanese geneticists believe that fish bran can reduce the carcinogenicity of dinitrocene and heterocyclic amine formed when frying grilled fish and meat by 92%.

3. Soybeans

Soybean not only refers to soybeans, but also includes black beans and green beans. Soybean is rich in nutrition and content. Protein content is 2 times higher than that of pork and 2.5 times higher than that of eggs. The content of protein is not only high, but also of good quality.

The amino acid composition of soybean protein is similar to that of animal protein, in which the proportion of amino acids is close to the needs of human body, so it is easy to be digested and absorbed. If soybean is eaten with meat and eggs, its nutrition can be comparable to that of eggs and milk, or even exceed that of eggs and milk.

Dietary fiber in bean dregs plays an important role in promoting good digestion and excreting solid waste. Appropriate cellulose supplementation can increase and soften the food in the intestine, promote intestinal peristalsis, thus speeding up defecation, preventing constipation and reducing the risk of intestinal cancer. At the same time, dietary fiber can obviously reduce plasma cholesterol, regulate gastrointestinal function and insulin level.

4. Oats

According to the comprehensive analysis of Health Research Institute of China Academy of Medical Sciences, naked oats in China contain 15.6% crude protein, 8.5% fat, heat released by starch, phosphorus, iron, calcium and other elements, which are among the best compared with other eight cereals. The water-soluble dietary fiber in oats is 4.7 times and 7.7 times that of wheat and corn, respectively.

Oats are rich in B vitamins, nicotinic acid, folic acid and pantothenic acid, especially vitamin E, which is as high as 15 mg per 100 g oat flour. In addition, oat flour also contains saponins (the main component of ginseng) which are lacking in cereals. Protein has a comprehensive amino acid composition, among which eight essential amino acids are the highest, especially lysine, which is as high as 0.68 g.

The porridge cooked with oatmeal is rich in magnesium and vitamin B 1, and also contains phosphorus, potassium, iron, pantothenic acid, copper and fiber, which can lower cholesterol and help fatty liver, diabetes and constipation. Uncooked oat bran is rich in magnesium, vitamin B 1, phosphorus and potassium, and also contains iron, zinc, folic acid, pantothenic acid and copper. Oatmeal can improve blood circulation and promote wound healing.

5.sweet potato

The fat content of sweet potato is extremely low, which is incomparable to other foods. But the content of unsaturated fatty acids is very rich. Take it as a staple food and eat it once a day. Its rich cellulose makes people feel "full of wine and food" and relaxed.

At the same time, it can not only prevent the absorption of fat and cholesterol in the intestine, but also decompose cholesterol in the body and promote lipid metabolism, which can effectively prevent overnutrition and resist obesity, thus achieving the purpose of losing weight.

Extended data:

High-fiber food refers to food rich in dietary fiber, which is beneficial to human health if eaten regularly. Dietary fiber is a part of plants, which is not digested by human body and has obvious health benefits to human body.

Dietary fiber has a certain health care effect on intestinal health, blood sugar regulation and prevention of type 2 diabetes, satiety and weight regulation, prevention of lipid metabolism disorder and prevention of some cancers. Whole grains, beans, fruits, vegetables and potatoes are the main sources of dietary fiber, and the content of nuts and seeds is also high.

Although foods rich in dietary fiber have all the above benefits, they are not partial eclipse. The correct dietary principle is to reduce fat intake, increase the proportion of vegetables and fruits, and maintain a balanced diet.

Carbohydrate consists of three elements: carbon, hydrogen and oxygen. Because the ratio of hydrogen to oxygen is two to one, just like water, it is called carbohydrate.

It is the cheapest of the three main nutrients and provides heat for the body. Carbohydrates in food are divided into two categories: effective carbohydrates that can be absorbed by the human body, such as monosaccharides, disaccharides, polysaccharides and ineffective carbohydrates that cannot be digested by the human body, such as cellulose, which is very important to the body.

Carbohydrate is the main energy source needed to sustain all living things. It is not only a nutrient, but also has some special physiological activities. For example, heparin in the liver has anticoagulant effect; Blood group sugar is related to immune activity.

In addition, the components of nucleic acid also contain carbohydrates-ribose and deoxyribose. Therefore, sugar compounds are more important to medicine.
