Just as there is no magic pill to prevent cognitive decline, no single almighty brain food can ensure a sharp brain as you age. Nutritionists emphasize that the most important strategy is to follow a healthy dietary pattern that includes a lot of fruits, vegetables, legumes, and whole grains. Try to get protein from plant sources and fish and choose healthy fats, such as olive oil or canola, rather than saturated fats.
GREEN VEGGIES
Leafy greens such as kale, spinach, collards, and broccoli are rich in brain healthy nutrients like vitamin K, lutein, folate, and beta carotene. Research suggests these plant-based foods may help slow cognitive decline.
FATTY FISH
Fatty fish are abundant sources of omega-3 fatty acids, healthy unsaturated fats that have been linked to lower blood levels of beta-amyloid the protein that forms damaging clumps in the brains of people with Alzheimer’s disease.
BERRIES
Flavonoids, the natural plant pigments that give berries their brilliant hues, also help Improve memory, research shows.
TEA+COFFEE
Coffee and tea might offer more than just a short-term concentration boost. In a recent study participants with higher caffeine consumption scored better on tests of mental function.
WALNUTS
Nuts are excellent sources of protein and healthy fats, and walnuts in particular might also improve memory, according to a study.
