Broccoli
Broccoli contains potent plant compounds, such as antioxidants. It also contains high amounts of vitamin K, providing 100% of the Recommended Daily Intake (RDI) in a 1-cup (160-gram) serving of cooked broccoli. Vitamin K is a fat-soluble vitamin that helps with the formation of sphingolipids, a type of fat that is found on brain cells. Several studies in older adults show that high consumption of vitamin K helps boost memory health and cognitive ability.
Broccoli also contains various compounds that give it antioxidant and anti-inflammatory effects, which may protect the brain against any form of damage.
