Onions are one of the most useful vegetables. There are many types of onions. White, yellow and red onions are sold in the markets. I wonder which of these is the most useful?
Studies by Canadian scientists have shown that red onion has the most beneficial properties among all types of onions. The study was published in the prestigious journal Food Research International.
Quercetin and anthocyanin antioxidants in red onions have the ability to strengthen blood vessels and thus reduce the risk of cardiovascular disease. Quercetin and anthocyanins slow down the aging process in the body, reduce the destructive effects of free radicals on the body, cleanse the body of old cells.
Compared to other types of onions, red onions have a stronger anti-cancer effect. Also, red onion better stimulates human immunity. According to its useful properties, yellow onion is in the second place, and white onion is in the third place. White onion has a very soft and pleasant taste, which is good to add to salads.
