You can eat more when you lose weight.
Onion is rich in nutritional value and is known as the "vegetable queen" abroad. According to scientific determination, every100g onion contains 40mg of calcium, 50mg of phosphorus,1.8mg of iron and 8mg of vitamin C, and also contains carotene, vitamin B 1 and nicotinic acid. More importantly, onions contain almost no fat.
In addition, onion also contains prostaglandin A, which is a strong vasodilator, which can reduce the resistance of human peripheral blood vessels and coronary arteries, reduce "bad blood lipids" and prevent thrombosis. At the same time, prostaglandin A can resist the action of pressor substances such as catecholamine in human body, promote the excretion of sodium salt, and thus lower blood pressure, so it has a health care effect on patients with hypertension, hyperlipidemia and cardiovascular and cerebrovascular diseases.
Dr. Kaido Gerwich, a professor of cardiology at Harvard Medical School in the United States, pointed out that eating half an onion raw or drinking the same amount of onion juice every day can increase the number of patients with heart disease by about 1/4.
30% high density lipoprotein cholesterol (HDL) content. Sun, director of the Second Department of Nutrition, Peking University First Hospital, pointed out that HDL is called "good cholesterol" and helps to prevent atherosclerosis. Onions are really good for heart patients, and they are best eaten raw.
Yu Kang, deputy director of the Nutrition Department of Peking Union Medical College Hospital, reminded everyone that onions are beneficial to patients with heart disease and hyperlipidemia, but it is unscientific to rely on certain foods to achieve the purpose of lowering blood lipids. It is also necessary to control the use of oil and cooperate with certain physical exercise.
It's going to be hot soon. I recommend a cold dish menu-beef with onion:
Ingredients: a small piece of cooked sauce beef and half an onion.
Ingredients: cucumber, green pepper, coriander seasoning: batter, sugar, monosodium glutamate, soy sauce, sesame oil.
Practice: wash onions and cut into small pieces, peel cucumbers and dice them, and dice peppers. Put the three dishes together, add salt and mix well, marinate for ten minutes, remove and drain, add seasoning and mix well. Dice beef, cut coriander into small pieces, add pickles and pour sesame oil and mix well. Serve.
Expert comment: Eating raw onion and cold salad can best play the role of onion in lowering blood fat, while beef is a kind of red meat with low fat. This dish is light and light. Cucumber and green pepper are rich in vitamin C, which is more suitable for heart patients.
