20 Foods That Can Actually Bring You Happiness

5. Blue Potatoes

Blue potatoes aren't a common supermarket find, but they're worth looking out for on your next trip to the farmer's market. The spuds get their color from anthocyanins, powerful antioxidants that provide neuroprotective benefits like bolstering short-term memory and reducing mood-killing inflammation. Their skins are also loaded with iodine, an essential nutrient that helps regulate your thyroid, staving off exhaustion and depression along the way.
