Why does eating onions make you fart

Onion is a food with a particularly strong taste. People usually use it to stir-fry dishes. Of course, some people like to eat onions raw, which has a higher nutritional value. Eating onions can help prevent cancer, but many people fart after eating onions. This is puzzling and makes people feel uncomfortable in public. So why does eating onions cause farting?

Raw onions have a pungent taste and smell, and especially can leave an unpleasant taste in the breath, so many people don’t like to eat onions, and even if they do, they’d rather eat cooked onions. However, biochemical research shows that it is these pungent substances that give onions excellent health functions such as anti-cancer.

The anti-cancer effect of onions is due to the active substance quercetin they contain. Quercetin can increase the expression of cancer suppressor genes, thereby killing cancer cells in the bud. It can also keep cancer cells in the initial stage and make them lose the ability to divide. Biochemical studies have shown that quercetin is present in high levels in onions. The quercetin bioactive substance in onions is easily inactivated when heated, thus losing its anti-cancer effect.

Quercetin has a good effect in treating prostate cancer. Onions contain a lot of quercetin, so prostate cancer patients can eat more of them. In the United States, quercetin is available as an over-the-counter drug for the treatment of prostate cancer and can be purchased over the counter. However, in China, the drug has not yet been approved as a prostate treatment. Quercetin can block the effects of androgens on hormone-dependent human prostate cancer cells. When the effects of androgens are blocked, the growth of prostate cancer cells is slowed or stopped.

To sum up, if you want to get more health benefits from onions, eating them raw or mixing them into salads is the best way. When eating heavy and greasy foods such as beef and mutton, pairing them with raw onions can help remove the greasiness and bring out a refreshing minty feeling.

When choosing onions, look for ones that feel heavy in your hand, have a dry, firm skin, no scratches, and no odor. The purchased onions should be placed in a cool, dry, dark and well-ventilated place.

The best way to fight cancer is to cut onion into shreds, cut celery into sections and marinate with a small amount of salt, cut pepper into shreds, cut coriander into sections, and cut pineapple into small slices. Add onion, celery, pepper, minced garlic and pineapple to the seasoning and mix together. Finally, add coriander and mix well. Serve.
