Flaxseed
Flaxseed is the most potent plant source of omega-3 fatty acids. Studies indicate that adding flaxseed to your diet can help reduce the development of heart disease by 46 percent. It helps keep red blood cells from clumping together and forming clots that can block arteries. Sprinkle one to two tablespoons of flaxseeds a day on your cereal, salad, or yogurt. Buy it pre-ground, and keep it refrigerated.
