Bananas

Bananas are not just delicious but also beneficial for your body. They have a unique combination of nutrients that make them particularly beneficial for your brain. Bananas are especially high in potassium, which is necessary to help regulate the fluid balance in the body, including in the brain’s cells.
A lack of potassium can lead to confusion and mental fatigue, so eating a banana will give you a nice boost of mental energy. Alpha-GPC, an amino acid found in bananas, has been found to increase cognitive abilities such as memory and learning because it helps nerves communicate more effectively.
