Broccoli

Broccoli contains a number of compounds that have powerful antioxidant and anti-inflammatory effects, including vitamin K. Broccoli are high in plant components, including antioxidants. It's also high in vitamin K, with a 1-cup (160-gram) portion of cooked broccoli providing more than 100% of the Recommended Daily Intake (RDI).

This fat-soluble vitamin is required for the formation of sphingolipids, a kind of fat found in tightly packed brain cells. A few studies in elderly persons have connected increased vitamin K consumption to improved memory and cognition. Aside from vitamin K, broccoli has a variety of chemicals that have anti-inflammatory and antioxidant properties, which may help protect the brain from harm.
