According to a report by the British Broadcasting Corporation on November 4, British research has found that a chemical substance in onions called quercetin can effectively prevent chronic inflammation that causes thickening of blood vessel walls, thereby reducing the risk of heart disease and stroke. Moreover, you don't need to eat a large amount of onions for this; a small amount each time can provide excellent effects. Researchers specifically pointed out that eating 100-200 grams of onions 2-3 times a week achieves the best results. If you really dislike eating onions, apples, tea, and red wine also contain quercetin, and moderate consumption can also help keep the heart healthy.
According to a previous report by the "Taiwan Times," the "red wine-soaked onion," which is very popular online, is even more effective than eating onions alone. [China Cuisine]
At that time, Hsiao Chen-ya, director of the pharmacy department at Hsinchu Hospital, who first pioneered this soaking method, stated that this formula actually came from Japanese literature and is scientifically based, not a folk "remedy." "I also have high blood pressure, diabetes, and a weak heart myself. I have been drinking this for 10 years and found it to be effective, which is why I recommended it to my friends," Hsiao said. "The preparation method is very simple. Use one bottle of unsweetened red wine (500 ml) and 1-2 peeled and chopped onions, place them in a large-mouth glass jar, seal, and let them soak. After a week, filter out the onions and it is ready to drink." An average person should drink 50 ml daily, while the elderly should drink 20-30 ml as appropriate. If you can tolerate it, it is best to eat the soaked onions as well.
Red wine-soaked onions not only has the effect of lowering blood pressure and blood sugar and protecting the heart, but also contains a variety of antioxidants, giving it certain anti-cancer and anti-aging effects. Even healthy people can drink a small amount daily.
