Bananas offer a significant daily intake of two key nutrients: vitamin B6 and vitamin C. Low intake of vitamin B6 has been associated with an increased risk of Parkinson’s disease, while increasing intake of vitamin C has been shown to slow cognitive decline in older people, and may decrease stress and improve mood in healthy adults.

Blueberry-nana Smoothie

Perhaps more than any other food, blueberries are associated with better brain health. Blueberries are a rich source of antioxidants and anti-inflammatories, making them a popular subject of studies on cognitive functioning. Many of these studies suggest that eating blueberries may protect against oxidative stress, improve memory and cognition, and even prevent cognitive decline.

Chocolate Banana Milkshake

Bananas may not be a major brain food, but they do offer a significant dose of vitamins B6 and C—both of which may promote better brain health. Dark chocolate and almonds both confer more significant brain benefits. Almonds are high in vitamin E, which may stave off Alzheimer's and dementia. Just a half cup of almonds provides nearly 100% of the recommended daily allowance of vitamin E. And chocolate is full of flavanols, antioxidant compounds that have been associated with good cognitive health.
