Citrus fruits
“Citrus is rich in vitamin C, the white netting around it is abundant in bioflavonoids which strengthen the blood vessels, and the peel is rich in limonene which is anticancer and anti-inflammatory,” Schoenfeld said. Incorporate them into your diet as a morning juice or an evening snack.
Also, a study published in the British Journal of Nutrition found that older people who eat citrus fruit frequently were 23 percent less likely to get dementia.
