These antioxidants help to neutralize harmful free radicals in the body, which can contribute to chronic diseases and aging.

The sulfur compounds in onions may have a vasodilatory effect, which can help relax blood vessels and improve blood flow.

Digestive Health: Onions contain dietary fiber, which is important for maintaining a healthy digestive system. Fiber supports regular bowel movements, helps prevent constipation, and supports gut health.
Cancer Prevention: Some studies suggest that the compounds in onions, particularly the sulfur compounds, may have potential anti-cancer effects. They could help inhibit the growth of cancer cells and reduce the risk of certain types of cancer, such as colorectal and stomach cancer.
Blood Sugar Regulation: Onions may have a positive impact on blood sugar levels. Some research indicates that certain compounds in onions may help improve insulin sensitivity, making them potentially beneficial for individuals with or at risk of type 2 diabetes.
