Poppy
These tiny black orbs are pleasantly crunchy and rich in B vitamins, which may help boost your brain function, says Halas-Liang. Shake them into vinaigrettes for salad or mix into jam for crunch. And, yes, the rumor is true: Eat too many of them and any drug tests you take may show up positive for opium.

Hemp seeds often come shelled and are also known as hemp hearts. Beyond having nine grams of protein per 3-tablespoon serving, hemp hearts also contain ALA omega-3s, zinc, magnesium, and vitamin E, Halas-Liang says. They’re often sold in pre-portioned packets, which make them a good option for stashing in your desk drawer. Try them atop salads and soups, or blended into a smoothie for a hit of nuttiness.
