Onions are one of the most commonly used vegetables all around the world. They are an inevitable ingredient in various cuisines because of the unique flavor they provide to the food being prepared. However, besides being delicious, onions also provide numerous health benefits, including their skin.
In case you were throwing the onion skin, after reading this article you will never do it again. Multiple studies have shown that the onion shell is high in antioxidants, even more than the onion itself, and it significantly boosts overall health.
The brown outer layer is a rich source of antioxidants, dietary fiber, and flavonoids, which promote skin health. Additionally, the onion skin is high in a potent pigment known as quercetin, which prevents clogging of arteries and reduces hypertension, has powerful sedative properties, and treats insomnia. Furthermore, It has powerful antibacterial, antioxidant, anticancer, and antifungal qualities.
The main ingredient in the skin of the onion, quercetin, is a potent flavonoid and antioxidant which destroy the main culprits for cancer, free radicals. Studies have shown that the skin is rich in insoluble fiber, which supports the proper peristaltic movements of the colon.
Furthermore, the insoluble fiber eliminates the accumulated toxins from the intestines, regulates the pH values, and prevents the formation of cancer cells.

Scientists explain that because of the fact plants can’t move around, they produce what they need, to defend, protect, and heal themselves. The compounds plants produce a reaction to stress can help you if being under similar circumstances.
This explanation adds up that plants would concentrate many of the protective compounds in their outer coverings, which is the point where most environmental assaults can take place.
The skin is not edible, but its benefits can be extracted by adding them in soups and stews and removing them at the end.
The next time you are preparing a soup, add a whole onion or two, along with the scales into the pot. This way you will extract quercetin and other beneficial compounds that are included in onions.
