Green leafy vegetables such as kale, spinach, and broccoli are rich in nutrients that are good for brain health.  These include vitamin K, lutein, folate, and beta carotene.  One green cruciferous vegetable that stands out is broccoli.  According to Raghavan (2018), broccoli may have anti-amnesic properties which help in the preservation of memory and may help you learn.  It contains a chemical called sulforaphane which may help in cognitive functioning.  Sulforaphane has antioxidant and anti-inflammatory properties that may support and even re-build damaged nerve cells in the brain.

For a quick, easy, and tasty way to eat broccoli, boil several florets and serve with finely grated white cheese, crumbled bacon and sunflower seeds on top!
