Onions: Are they Worth the Eye-watering Torture?

As a kid, if there was a list of vegetables I hated with a pure passion, onions would probably top the list. I hated it when my mother made me peel or slice onions. The eye-watering torture was enough to frighten any kid my age.

Now, as an adult, I am fascinated by the amazing benefits of this superfood, which kind of makes the whole eye-watering process of slicing them worth it.

Scientifically known as Allium Cepa, onions are a superfood, a gift of nature, and one of the best things that ever happened to human beings.  (Okay, before you begin to think this is one onion-crazed fellow, you should keep reading to learn about all the amazing things onions can do for you)

Due to its high concentration of sulfur compounds and amino acids, onions help clean up the digestive system and expel harmful toxins from the body. Yipee!

Anemia Management

A deficiency in Iron could result in anemia, which, unfortunately, is a fatal disease. Onions contain 0.2mg of iron per 100 gram and a substantial amount of folate. Folate is a phytochemical that helps absorb iron to its full potential and is often recommended to pregnant women.

Blood Sugar

The major challenge in managing diabetes is maintaining a safe blood sugar level. To achieve this, it is highly recommended to consume raw onions to help keep your blood sugar level in check.

Adopting a protein and potassium-rich diet could be helpful in preventing these hair related problems. Onions are known to promote hair growth and also treat and prevent dandruff. Mixing onion juice with yogurt and leaving it on the hair for half an hour can help strengthen your hair and cleanse your scalp.

Aging is a natural phenomenon, it is caused (prematurely) by the accumulation of the harmful elements that our skins absorb and also by the effects of free radicals. Onion, with their detoxifying and antioxidant properties, help slow down the aging process.

Stronger Bones

Studies have found that onions contain growth plate chondrocytes and also certain compounds that help rebuild connective tissues. These can be helpful in treating bone loss.

Better Vision


Onions contain sulfur which improves the health of the lens of the eyes. It stimulates the production of a protein named glutathione (which functions as an antioxidant). The higher the level of glutathione, the lower the risk of glaucoma, macular degeneration, and cataracts. Onions also contain selenium which aids the vitamin E in the eye (which protects the cells in the eye).

Great for Oral Health

As ironic as this may sound, onions do help your oral health, even though they most probably would give you bad breath. Onions contain thiosulfinates, and thiosulfonates (a.k.a the sulfur compounds) that help reduce bacteria that cause tooth decay. And eating them raw is best, as cooking might destroy some of these beneficial compounds.

They are also rich in vitamin C that can keep the teeth healthy. It is also believed that onions can relieve tooth pain.

Prevents Blood Clot

Onions have been found to contain rutin, a compound which can help prevent blood from clotting. Clots usually occur in the arteries and veins – in arteries, the clots are platelet-rich, while in veins, they are fibrin-rich. The rutin in onions helps block an enzyme called Protein Disulfide Isomerase,  which is released quickly when blood clots form.

Improves Brain Health

Research suggests that onions contain certain antioxidants which bind with the harmful toxins in the brain and flush them out of the body. And the sulfur-compounds in onions can also slow down age-related memory loss. However, a part of these memory fighting properties might be lost upon cooking. Hence, you might want to eat your onions raw!

Another sulfur-compound in onions, named di-n-propyl trisulfide, improves memory impairment. Onions are also believed to treat dizziness, epilepsy, and vertigo, although this has not been scientifically proven.
