Kale and Collard Greens
Plagued by spring allergies? Load up on leafy greens, such as kale and collard greens. Both contain high levels of phytochemicals, mainly carotenoids, which, research suggests, protect against the development of seasonal allergies. Carotenoids are best absorbed by your body when you eat them with some sort of fat, so dress your greens with olive oil or another one of these healthy fats.
