14 Health Benefits of Onion

2. Good Source of Vitamin C For Brain Health

Vitamin C is beneficial for many parts of the body. It has long since been used to help boost the immune system and more recently has become a staple skincare ingredient. Raw onions have a high level of vitamin C as well as phytochemicals. When the two are paired together in the raw form, they present a powerful tool that helps boost the immune system.

The vitamin C in onions also help support healthy brain function. Onion contains a high level of antioxidants in the skin and in the juice. These antioxidants bind with bad toxins that reach the brain and help to flush them back down past the blood/brain barrier and out of the body. All color onions have sulfur which can reduce the signs of aging both externally and internally. The di-n-propyl trisulfide found in raw onions has also been proven to help with memory impairment in adults.
