25 Foods to Include in Your Diet for Better Brain Health

20. Kale

Eating just one-and-a-half servings of leafy green vegetables like kale each day could slow the decline of brain function in older adults. Studies found that certain nutrients associated with good brain health — lutein, nitrate, vitamin K, and folate — are abundant in kale and other leafy greens. A single cup of raw kale also has significant amounts of protein for a leafy green.

Working with the other nutrients in kale — iron and vitamin B6 — help the brain produce healthy levels of the neurotransmitters serotonin and dopamine that regulate mood, making kale the perfect brain food.
