Asparagus : The B vitamin is essential in helping you keep your cool when stress rears its ugly head. Steam some spears and add to salads or stir-fries

Avocados : They contain more folate than any other fruit . Try to stick to a single serving (about one-quarter of an avocado). Thinly sliced, it can go a long way on salads or replace mayo on sandwiches or burgers

Berries : They are vitamin C powerhouse that tough skin keeps them protected while they’re bouncing around in your purse or backpack, so you can tote them anywhere. Try some other varieties, like clementines, tangelos, or mineolas

Oysters : They are a mother lode of zinc. Six oysters—what you’d typically be served in a restaurant as an appetizer—have more than half the recommended daily allowance for this important calming mineral

Walnut : The  omega-3 fatty acids in walnuts keep the stress hormones cortisol and adrenaline in check. To bring out their flavor, I toast them for 10 minutes, then chop them and add them to salad
