Oranges

One medium orange contains nearly all of the vitamin C you require for the day. This is vital for brain health since vitamin C is an important element in avoiding mental deterioration. Higher levels of vitamin C in the blood, according to one study, were connected with gains in activities involving focus, memory, attention, and decision speed.

Vitamin C is a potent antioxidant that aids in the battle against free radicals that can harm brain cells. Furthermore, vitamin C promotes brain health as you age and may protect against illnesses such as severe depression, anxiety, schizophrenia, and Alzheimer's disease. Other foods that are high in vitamin C include bell peppers, guava, kiwi, tomatoes, and strawberries.
