Peas
Though green peas are one of the first vegetables to poke their heads out in spring, the season for them lasts, in some areas, just two weeks. So eat them up now! Just one cup will provide you with an entire day's worth of allergy-fighting vitamin C, and peas are one of the best sources of thiamin, or vitamin B1, a vitamin that boosts your mood and wards off depression.
