Let's fall in love with N reasons to eat onions
Reason 1: Sterilization, anti-cold
Onion contains phytoncide such as allicin, has a strong bactericidal ability, can effectively resist influenza virus, prevent colds. When this phytoncide is excreted through the respiratory tract, urinary tract, and sweat glands, it can stimulate the secretion of cell walls at these locations, and therefore has the effects of phlegm, diuresis, sweating, and antibacterial and antiseptic functions.
The second reason: to promote gastrointestinal motility and help digestion
The onion contains onion and garlic, with a strong aroma. It often makes people cry because of the pungent smell. It is this special smell that stimulates the secretion of gastric acid and increases appetite. Animal experiments have also proved that onion can increase the gastrointestinal tract tension, promote gastrointestinal motility, and thus play an appetizing role, has a significant effect on the loss of appetite caused by atrophic gastritis, gastric insufficiency, indigestion and so on.
Reason 3: Prevent Cancer
The anti-cancer efficacy of onions comes from its rich selenium and quercetin. Selenium is an antioxidant that stimulates the body's immune response, thereby inhibiting the division and growth of cancer cells, while also reducing the toxicity of carcinogens. Quercetin can inhibit the activity of cancer cells and prevent the growth of cancer cells. A survey showed that people who eat onions are 25% less likely to suffer from stomach cancer than those who do not eat, and 30% less on stomach cancer.
Reason 4: Lower blood pressure
Onion is the only plant that contains prostaglandin A. Onion is the only food known to contain prostaglandin A. It is a natural blood thinner. Prostaglandin A can dilate blood vessels and reduce blood viscosity, which will reduce blood pressure and reduce peripheral blood vessels. And increase the blood flow of coronary arteries to prevent thrombosis. The role of vasopressor substances such as catecholamines in the human body can also promote the excretion of sodium salts, thereby lowering blood pressure. Regular consumption of foods has a health effect on hypertension, hyperlipidemia, and cardiovascular and cerebrovascular diseases.
Reason 5: Hypoglycemic
Onions also have a hypoglycemic effect, because onions contain organic substances similar to the hypoglycemic agent sulfadicin, and in the human body can produce a powerful diuretic effect of picolin. Diabetic patients can eat 25~50g of onion at every meal to have a good effect of lowering blood sugar and diuresis.
Reason 6: Improve constipation
Sulfur components of onions are combined with bacteria in the large intestine and proteins, or bacteria in the intestine to form hydrogen sulfide, which can promote bowel movements. Abundant soluble dietary fiber can stimulate the intestines to make exercise more vigorous, and oligosaccharides can also inhibit the proliferation of bad bacteria in the intestine, effectively improving the common symptoms of constipation in girls.
