Berries. High in fiber, berries are naturally sweet, and their rich colors mean they are high in antioxidants and disease-fighting nutrients.
How to include them: When berries are not in season, it is just as healthy to buy them frozen. Add to yogurt, cereals, and smoothies, or eat plain for a snack.
Fish. Fish can be a good source of protein and omega-3 fatty acids, which help prevent heart disease.
How to include it: Buy fresh, frozen, or canned fish. Fish with the highest omega-3 content are salmon, tuna steaks, mackerel, herring, trout, anchovies, and sardines.
Leafy greens. Dark, leafy greens are a good source of vitamin A, vitamin C, and calcium, as well as several phytochemicals (chemicals made by plants that have a positive effect on your health). They also add fiber into the diet.
How to include them: Try varieties such as spinach, swiss chard, kale, collard greens, or mustard greens. Throw them into salads or sauté them in a little olive oil. You can also add greens to soups and stews.
