Regular grains can prevent osteoporosis
According to statistics from the Ministry of Health, about 1/4 of women and 8% of men aged 60 and over have different degrees of osteoporosis.
Osteoporosis is a common metabolic bone disease, which is characterized by reduced bone density, loss of bone mass, increased fragility, and prone to fracture.
Because osteoporosis patients are asymptomatic, the disease progresses to a certain degree, which is prone to lumbar fractures or hip fractures, resulting in bedridden, which seriously affects the quality of life of the elderly.
Medical experts at home and abroad agree that the occurrence of osteoporosis is related to a sharp decrease in estrogen secretion in the body, so elderly women after menopause are more likely to suffer from osteoporosis than elderly men.
Dr. Wei Huacheng, a doctor from the United States, discovered that isoflavones from soybeans (such as “genistein”, “soybean plasma”, etc.) are natural medicines to prevent osteoporosis.
Because soybean isoflavones are “phytoestrogens” and their structure is very similar to the natural estrogen in the human body, phytoestrogens are often supplemented to correct various metabolic diseases caused by decreased estrogen levels in the human body.
There are more than 20 kinds of phytoestrogens that have been found abroad. According to their structure, they are classified as isoflavones, saponins, lignans (lignans), coumarin, phytosterols and rancidates, etc.Among them, legume “soybean” contains the largest amount of phytoestrogens.
Other foods such as wheat (wheat bran), rice (rice bran), buckwheat, cruciferous vegetables (such as broccoli), potatoes, jujube, certain fruits (such as apples, cherries, pomegranates, etc.) and corn flour and certain Chinese herbs (Such as snake bed, Epimedium) and so on also contain a certain amount of phytoestrogens.
Japanese people have a lower incidence of osteoporosis because they like tofu (the Japanese per capita consumption of tofu is the highest in Asia) and they like to drink “miso soup” cooked with watercress and eat soba noodles.country.
To verify the health effects of phytoestrogens, Dr. Wei and his assistants performed animal experiments: They divided 6-week-old rats into sections, each of which was fed daily with soy milk and buckwheat noodles; the other group was fed onlyWater and ordinary and ordinary feed.
A few weeks later, the results showed that the bone density of rats fed soy milk and buckwheat noodles was much higher than that of rats fed water and ordinary feed.
Medical researchers believe that soy milk (or soy products) and grains are the best natural medicines to prevent osteoporosis.
Because of the isoflavones they contain, phytoestrogens like lignans help the body absorb calcium and increase bone density.
Therefore, middle-aged and elderly people should not drink a glass of soy milk or eat some soy products every day.
