You’ll Never Throw Another Onion Skin Away After Reading This!
Use Onion Skins in Soups and Stews
The onion skin itself is not edible but can easily be added to a soup or stew base. It can also be used for making homemade chili. The quercetin is a potent antioxidant flavonoid with anti-tumor benefits and is very rich in antioxidants. Quercetin levels are highest on and near the onion skin. Quercetin is also a sedative, which is why the onion tea is best when consumed at bedtime. Do not take onion skin during pregnancy or while breastfeeding.
Study Shows Onion Skins High in Dietary Fiber
According to a study published in the journal Plant Foods for Human Nutrition, the brown onion skin could be used as a valuable dietary ingredient because it is extremely high in non-soluble dietary fiber. Soluble and insoluble fiber are both undigested by the body. Fiber is not absorbed into the bloodstream but is excreted from the body. Insoluble fiber removes toxic waste from the colon and keeps the pH in the intestines at optimal levels. Insoluble fiber keeps the body regular and promotes bowel movements. This helps prevent microbes from making cancerous substances.
Eating fiber also helps reduce the risk of many health conditions such as cardiovascular disease, colon cancer, obesity and type 2 diabetes. The study also noted the powerful phenolic compounds, namely quercetin and other valuable flavonoids. Flavonoids are the parts of the plant with medicinal properties.
So the next time you are in the kitchen preparing for a meal think before you throw out those onion skins. Why throw away something that can be so valuable to your body and have such a great source of antioxidants?
