Housewives don't like to cook with onions, which will make people cry. Many people are also afraid of the smell of onions. Unless it's an excellent onion dish, it's really hard to find onion lovers. But people who want to make their bones strong, grow tall and prevent osteoporosis had better eat onions through their noses.
Because the latest research report of the authoritative magazine Nature points out that in recent years, Swiss scientists have found that eating onions often can improve bone density, because onions also contain some calcium, which helps to prevent osteoporosis; The effect of onion on preventing bone loss is even better than that of osteoporosis drug calcitonin. The researchers asked male mice to eat one gram of dried onions every day. After one week, the average bone mass of male rats increased by 13. 5- 18%。 Another group of experiments found that letting mice eat mixed vegetables containing onions can also reduce the problem of bone loss. In experiment 3, the ovariectomized female rats ate1.5g onion every day, and the bone loss rate decreased by 25%.
What's more noteworthy is that the health care function of onion can be seen in just 12 hours. Researchers believe that the function of onion may come from "preventing bone loss", so people who want to use onion for health care may eat 200-300 grams (10 ounce) of onion every day to prevent osteoporosis. Medicine and food are homologous. In our daily food, there are many fruits and vegetables with similar drug effects.

Eating half an onion raw every day, or drinking the same amount of onion juice to protect the heart, is a folk prescription. Dr. Kedo conducted experiments on patients in his own clinic, which proved that onions do have the effect of raising cholesterol, but the more onions are cooked, the less effective they are.

Because onions contain no fat, Dr. Kedo asked the heart patients in the clinic to eat onions every day.

The physiological function of glutathione is to transport oxygen for cell respiration. With the increase of human selenium content, the incidence of cancer will be greatly reduced. Selenium can stimulate human immune response, thus inhibiting the division and growth of cancer cells and reducing the toxicity of carcinogens. Quercetin can inhibit the activity of carcinogenic cells and prevent the growth of cancer cells.
