The benefits of soybean to men are mainly reflected in protecting prostate. Professor Sacher pointed out that studies show that drinking a cup of soy milk every day can reduce the risk of prostate cancer in men by 30%. Drinking two glasses can reduce the risk by 70%. He explained that this is mainly because after people eat soybeans and their products, a substance will be decomposed in the intestines, which can inhibit the formation of hydroxytestosterone, which is likely to cause prostate cancer. This substance can also prevent hair loss, which is undoubtedly a boon for men who have a tendency to lose hair.
In addition, compared with meat, beans are rich in protein, but contain no cholesterol, and the content of saturated fatty acids which are harmful to human body is very low, which is more beneficial to health. Many men cherish their bodies very much. protein, which is rich in beans, can supplement the muscles and strengthen the fitness effect.
Professor Sacher said that soybean has some similar benefits for both men and women: first, it is rich in carbohydrates and will not raise people's blood sugar level. Secondly, experiments have proved that if you eat 1/3 cups of soybeans or bean products every day (each cup is about 240 ml), you can prevent cardiovascular diseases. Third, soybean can promote the growth of beneficial bacteria in the gastrointestinal tract, which is good for promoting digestion and preventing rectal cancer. Fourth, eating more soybeans can also prevent osteoporosis. Dr. james anderson, who studies soy foods at the University of Kentucky, believes that some men are suspicious of soy products, mainly because soy is rich in isoflavones, which are estrogen analogues. However, a recent experiment in the United States shows that the consumption of soybeans in daily life will not cause testicular atrophy and breast growth in men at all, so there is no need to bear it at all
"Bean products
Nutritional function "
Shen Lin, an internationally registered junior dietitian
As the saying goes, "People take food as the main food", which is more important for patients. More and more people attach importance to and admire scientific and practical nutrition supply, and provide scientific and practical nutrition for patients. Many diseases especially need nutritional treatment, such as diabetes, hypertension, anemia, night blindness, burns and liver and kidney diseases, which directly affect the treatment and rehabilitation of patients.
The ancients said, "A saint can't cure a disease without curing it." In the ancient society, when people were looking for food, they found many drugs with therapeutic effects. Some commentators said that "medicine and food are homologous". In recent years, clinical nutrition has been gradually recognized and valued by medical workers and the general public.
Let's read about beans and their products.
First, the classification of beans
1, according to the nutritional composition and content of beans can be divided into two categories, one is soybeans such as soybeans, green beans and black beans; Second, other kinds, such as peas, lentils, sword beans, mung beans, cowpeas, red beans, broad beans and so on.
2. According to the properties of beans, they are divided into cool (cold), wet (hot) and peaceful.
3. According to the theory of beans entering the meridian of traditional Chinese medicine, mung beans and red beans enter the heart meridian; Lentils and peas enter the spleen meridian; Talking about Douchi Returning to Lung Meridian; Black beans, broad beans and black beans enter the stomach meridian; Adzuki bean belongs to small intestine meridian.
Second, the nutritional value of soybeans
1, soybean contains 35%-40% protein, and protein contains many essential and non-essential amino acids. Except methionine and cystine, other amino acids are similar to those of animals, and the total protein content is higher than that of meat.
2. The content of fat15%-35%, of which 85% is unsaturated fatty acid, the content of oleic acid is more than 50% and oleic acid is more than 26%.
3, containing carbohydrates 25%-35%. Mainly starch and sucrose, cotton seed sugar and stachyose which can't be absorbed by human body, and half of the carbohydrates in soybean are hidden sugar which can't be absorbed by human body.
4. Soybean is rich in iron, vitamin B 1, B2 and trace elements such as vitamin A, vitamin D, phosphorus, iron and selenium.
5. Soybeans contain saponins and soybean isoflavones, which have antioxidant, hypolipidemic, anti-hemolytic, anti-fungal, anti-tumor and estrogen-like effects.
Third, the anti-nutritional factors of soybean
1 contains protein enzyme which inhibits trypsin, pepsin and chymotrypsin in the digestive tract, which has negative effects on human or animal growth due to its inhibitory effect on the digestive system.
2. The phytohemagglutinin (PHA) can agglutinate human and animal red blood cells.
3, containing oligosaccharides, stachyose and raffinose can not be digested and absorbed by the intestine, and are fermented by intestinal microorganisms to produce gas, which is one of the causes of flatulence.
There are some anti-nutritional factors in soybean, which make its protein digestibility only about 65%. How to improve the digestion of soybean and make it into bean products such as tofu, soybean milk, yuba, bean sprouts, lobster sauce and fermented bean curd, its protein absorptivity can reach 95%, which is a low-cost and nutritious food in daily life.
Fourth, eating beans has many benefits.
In our daily diet, eating more bean products has many benefits for disease prevention and fitness. Let's take a concrete look at the health and nutrition effects of tofu, yuba, soybean milk and bean sprouts processed into bean products: (1) The contents of protein and iron in soybean milk are higher than that in milk; (2) Bean sprout is a good fresh vegetable, which is rich in vitamin C in addition to protein. (3) The vitamin B2 content of yuba is the highest in bean processing.
Five, the health care function of soybean products
1, prevention of osteoporosis
In bones, calcium exists in the form of inorganic salt, which is the main component of human bones. The main cause of osteoporosis is calcium deficiency. Bean products are rich in calcium and a certain amount of vitamin D. The combination of the two can effectively prevent osteoporosis.
2, improve the body's immunity:
The body needs different nutrition at different ages and under different physiological conditions. In order to improve the body's immunity, balanced nutrition must be obtained through a reasonable diet. Bean products are rich in lysine, unsaturated acid, starch sucrose and various vitamins and minerals.
3. Prevent constipation:
Constipation is caused by slow intestinal peristalsis, food residues staying in the intestine for too long, and intestinal water being absorbed too much. For a long time, enterotoxin was absorbed by the human body, which was a cause of intestinal cancer. Bean peristalsis provided sufficient nutrients to the intestine, which had a positive effect on the prevention and treatment of constipation, anal fissure, hemorrhoids and intestinal cancer.
4. Prevention of cardiovascular and cerebrovascular diseases
The risk factors of cardiovascular and cerebrovascular diseases are high-fat diet, obesity, hyperlipidemia, hypertension, etc. Soysterol and unsaturated fatty acids contained in bean products have good lipid-removing effect, and their calories are very low, which can reduce weight. The intake of soybean after enzymatic hydrolysis has a good effect on preventing cardiovascular and cerebrovascular diseases in obese middle-aged and elderly people.
5, weight loss effect
The fat content of bean products is extremely low, and carbohydrates can only be absorbed by half. Obese people not only feel full after eating, but also have lower calories than other foods, so it is beneficial to lose weight.
6, slow menopause:
Bean products are rich in estrogen, vitamin E and phospholipids necessary for brain and liver, which have obvious effects on delaying aging and improving menopausal symptoms in more advanced women.
The consumption of bean products also has a certain effect on the treatment of diseases. Bean products belong to high-quality protein, with more lysine and less methionine. They are the only plant food that can replace animal protein, but people with kidney diseases such as nephrotic syndrome, acute and chronic glomerulonephritis, renal failure, gout and skin diseases should not eat too much.
