Purple onion and white onion are two different varieties of onions. They are very common in our lives, and people have been arguing about their nutritional value. Some people say that purple onion has high nutritional value, while others say that white onion has high nutritional value. So who is right? Purple onion or white onion, which one has higher nutritional value?1. The nutritional content of purple onions and white onions is similar Both purple onions and white onions contain carbohydrates, ash, retinol, niacin, dietary fiber and various minerals. The ingredients are almost the same, but there is a certain difference in the content. The content of vitamin C and some natural anti-inflammatory ingredients in white onions is higher than that in purple onions, and its anti-inflammatory and bactericidal effects are better than those of purple onions. 2. Purple onions are high in allicin and selenium sulfide Among the trace elements contained in purple onions and white onions, the content of allicin and selenium sulfide in purple onions is higher than that in white onions. After entering the human body, these substances can inhibit the formation of carcinogenic nitrosamines, increase the activity of phagocytes, prevent cell canceration, and inhibit the regeneration of cancer cells. The anti-cancer effect of purple onions is more outstanding than that of white onions. 3. Purple onions are high in quercetin Purple onions also contain a nutrient that white onions do not have, which is quercetin. After entering the human body, this substance can produce a glycoside under the induction of flavonols, and this glycoside has a significant diuretic and swelling-reducing effect, which can prevent body edema and urination problems. In addition, this quercetin substance can also accelerate the burning of fat in the body and promote the metabolism of cholesterol. It has a significant preventive effect on human obesity, hyperlipidemia and arteriosclerosis, but white onions do not have this effect. |
