Citrus Fruits: It might seem like the only trees of the season are covered in ornaments, but citrus fruits have their best showing in the winter months. Packed with vitamin C, everything from grapefruits to clementines are delicious and affordable this time of year. A powerful antioxidant, studies show that vitamin C can help reduce stress levels and offer immune-boosting qualities. Citrus fruits make quick fiber-filled snacks, as well as tasty additions to salads to add bright colors and a kick of sweetness without a lot of calories.
