Healthy benefits of Onion

Onions are part of the allium family of vegetables and herbs, which also includes chives, garlic, scallions, and leeks. Allium vegetables have been cultivated for centuries for their characteristic, pungent flavors and for their medicinal properties.

The onion is most frequently a biennial or a perennial plant but is usually treated as an annual and harvested in its first growing season. Onions are cultivated and used around the world.

Onions can vary in size, shape, color, and flavor. The most common types are red, yellow, and white onions. Flavors can be sweet and juicy to sharp, spicy, and pungent, often depending on the season in which they are grown and consumed.

These vegetables contain various vitamins, minerals and potent plant compounds that have been shown to promote health in many ways.

So, here are some surprising benefits of Onions.

  • The flavonoids in red onions can contribute to heart health. Onions are also rich in organosulfides, which can help prevent heart disease.

  • Onions are nutrient-dense, meaning they’re low in calories but high in vitamins and minerals.

  • This vegetable is particularly high in vitamin C, a nutrient involved in regulating immune health, collagen production, tissue repair, and iron absorption.

  • One study has proven that onion extract can help lower blood sugar levels. The study was conducted on diabetic rats, and the results were encouraging. One of the sulfur compounds in onions (S-methyl cysteine) and quercetin can have beneficial effects on blood sugar.

  • Onions have antihistamine effects due to quercetin, an antioxidant that acts like an antihistamine and an anti-inflammatory agent. In test tubes, quercetin has proven to prevent immune cells from releasing histamine, which are chemicals that cause an allergic reaction.

  • Raw onion is known to lower the production of LDL (bad cholesterol) and keep your heart healthy.

  • Quercetin, a powerful compound found in onions, has been suggested to play a role in preventing cancer, especially stomach and colorectal cancers.

  • A mixture of onion juice and honey (which helps make it less pungent) is said to be effective as a cure for fever, common cold, allergies, etc.

  • Keep a small piece of onion under the nostrils and inhale, to stop or slow down a nose bleed.

  • The vitamin C helps the formation of collagen that is responsible for skin and hair health.

  • Chewing raw onions improve our oral health. They help eliminate bacteria that can lead to tooth decay and gum issues.

  • The phytochemicals in onions along with their vitamin C help improve immunity.

  • Onions scavenge free radicals, thereby reducing your risk of developing gastric ulcers.

  • Those bright green tops of green onions are rich in Vitamin A, so do use them often.

  • Folate, found in onions, might help reduce depression. Homocysteine prevents blood and other nutrients from reaching the brain, and folate prevents this chemical from building up. Excess homocysteine also interferes with the production of the feel-good hormones serotonin, dopamine, and norepinephrine, which regulate not only mood but also sleep and appetite.

  • Onions help reduce oxidative stress, boost antioxidant levels and decrease bone loss, which may prevent osteoporosis and boost bone density.

  • Onions can fight potentially dangerous bacteria, such as Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and Bacillus cereus.

  • Onions are a rich source of fiber and prebiotics, which are necessary for optimal gut health.

  • Onions are particularly rich in the prebiotics inulin and fructooligosaccharides. These help increase the number of friendly bacteria in your gut and improve immune function.

  • Onion juice can work great to relieve earache.

  • Onions contain prebiotics, which, as per a study, can improve sleep and even reduce stress.

  • The sulfur in onions improves the health of the lens of the eye. It stimulates the production of a protein named glutathione, which acts as an antioxidant. Higher levels of glutathione mean a reduced risk of glaucoma, macular degeneration, and cataracts.

  • Onions were found to have an inhibitory effect against V. cholerae, the microbe responsible for cholera. This can be attributed to the antibacterial effects of the vegetable.

  • Onions contain a compound called rutin, which can help prevent blood from clotting. In numerous mice studies, rutin was found to be the most potently anti-thrombotic compound.

  • The fiber in onions slows digestion and keeps the energy levels stable.

  • Taking onion juice with honey is known to increase fertility in men.
