Citrus fruits

Due to their high nutritional value, citrus fruits have been linked to a number of health benefits, including the support of brain function. Citrus fruits like oranges and grapefruit are rich in flavonoids, such as hesperidin, naringin, quercetin, and rutin, among others, just like berries. These compounds could be able to improve learning and memory as well as protect nerve cells from damage, delaying the incidence of mental decline.

Citrus fruit juice may help to improve mental function, according to studies. A test that required matching symbols to numbers was performed on 40 young adults, and the results showed that consuming 17 ounces (500 mL) of 100% orange and grapefruit juice increased blood flow to the brain and considerably improved performance when compared to a control drink. To make your snack more nutritious, combine citrus fruits and citrus juice with a source of protein and healthy fat, such as mixed nuts.
