Onions offer a lot of health benefits, including serving as a source of antioxidants. Soluble fiber and flavonoids are also provided by onions. Flavonoids help minimize or reduce inflammation and protect against cancer.
The nutrients in onions also support the health of nerves and the cardiovascular system, and they help maintain healthy hormones. People with high cholesterol or high blood pressure also benefit from onions. Onions prevent hardening of the arteries and maintain blood vessel elasticity, which helps mitigate risks of these health conditions. Type 2 diabetes and obesity are other health problems onions combat because they modify the impact of sugar.
