Top Health Benefits of Onions:

  • Prevents Diabetes: A single serving of onions contains 27% of your biotin DRI. Biotin has many positive impacts on your health, one of which is combatting symptoms associated with type 2 diabetes. Early research suggests that a combination of biotin and chromium might help regulate blood sugar and even decrease insulin resistance.
  • Healthy Skin: Biotin is also important in maintaining healthy skin. It is used to treat brittle nails, prevent hair loss (although research is still ongoing as to its effectiveness in this regard) and maintain skin health.
  • Improved Immunity: Onions contain both vitamin C and phytochemicals that increase the effectiveness of vitamin C in your body. What does that mean? A healthier, more effective immune system, that’s what.
  • Prevents Cancer: Quercetin is more than just a funny looking word. It’s also a plant flavonoid (another funny word that means plant pigment) that possesses potent antioxidants, which fight against cancer-causing free radicals. Free radicals are chemical compounds that damage cell membranes and cause cell death. Onions are rich in quercetin and thus are a powerful weapon in the war against cancer.
  • Relieves Stress: Quercetin doesn’t stop there. It also helps protect your body against stress. When you are stressed out your body produces cortisol. While cortisol is totally normal, too much of it can damage muscle tissue and cause protein breakdown in the body. That’s where quercetin-rich onions come in. During times of prolonged stress, quercetin suppresses enzyme required for cortisol release. Next time you have a stressful deadline to meet at work, bring along a few raw onions to snack on!

Well it also helps prevent plaque buildup in arteries which is also good for preventing heart attack and stroke.
