Broccoli is a source of two crucial nutrients that help improve brain function. Vitamin K helps to strengthen cognitive abilities while Choline has been found to improve memory – people who eat plenty of broccoli perform better on memory tests. Broccoli also includes a sizeable serving of folic acid, which can help ward off Alzheimer’s disease. Studies suggest that a lack of folic acid could lead to depression, so eating plenty of broccoli could also keep you happy.

A chemical known as sulforaphane, which is found in cruciferous vegetables like broccoli, can help improve cognitive functions after a traumatic brain injury. When it is administered into the body, the chemical helps in reducing swelling or oedema in the brain. Studies suggest that sulforaphane in the broccoli, which has antioxidant and anti-inflammatory properties, can help rebuild damaged neural cells in the brain.
