This hearty green is rich in magnesium—and when you’re low in this mineral, you can end up feeling tired, irritable, and even foggy, says Young.

High-protein foods, such as Greek yogurt, can spur the creation of life-is-good brain chemicals like dopamine and norepinephrine and also rev up our energy levels and alertness, says Young.

Berries get their color from a purple pigment called anthocyanin, which is a mood enhancer, says Young. What’s more, all berries are high in fiber and water, so you feel full for a longer period of time when you eat them.
