The quercetin in onions is a type of flavonoid that helps fight blood clots, inflammation, and oxidation. It can also help reduce cholesterol in the blood and scavenge free radicals in the body. Onion contains prostaglandin A, which is a strong vasodilator, which can reduce blood viscosity, increase coronary blood flow, and play an auxiliary role in the prevention and treatment of cardiovascular and cerebrovascular diseases such as hypertension and hyperlipidemia. A variety of nutrients contained in onions protect cardiovascular health in various ways. Therefore, in cardiovascular diseases, onions have the reputation of “heart stents”.

It is recommended that the daily consumption of onion is about 100 grams, which is equivalent to half of a medium-sized onion. Different foods can provide different nutrients.

Regardless of whether it is raw or cooked, the stomach is prone to gas production after eating onions, causing abdominal distension and abdominal pain. Therefore, it is not recommended for patients with gastrointestinal surgery to eat onions. In addition, people who are prone to allergies and those suffering from itchy skin diseases are not recommended to eat onions.

Answer: No. Experts said that although 100 grams of onion juice has a certain bacteriostatic effect within a certain period of time, the bacteria may resume growth in the later stage, so how many onions should be eaten to achieve the bacteriostatic effect cannot be calculated by the human body. According to the popular diet, daily intake of 100 grams of onions has no bactericidal effect.

Answer: Yes. Experts said that through experiments, it was found that onions do contain some polyphenolic compounds, which have antioxidant effects.
