One often-overlooked “superfood” is flaxseed.

Flax is the plant at the root of linen clothing. Nutritionists point out that flaxseed is loaded with antioxidants for a healthy heart. The seeds are considered the richest plant source of alpha-linolenic acid (ALA), a source of omega-3 fatty acids that help regulate blood pressure, blood sugar and cholesterol levels.

Flaxseed has also been associated with a lowered risk for breast cancer while helping to soothe the symptoms of menopause. The seeds are filled with a phytochemical called lignan, a type of plant-based estrogen. This is why flaxseed is being studied closely as an alternative for hormone-replacement therapy for women who experience hot flashes, mood swings and other symptoms of menopause, and the estrogen link is being studied for the prevention of breast cancer.

Adding flaxseed to your diet is easy. Nutritionists recommend ground seeds rather than whole seeds because they are more easily digested. Add a spoonful to a bowl of cereal, baked goods, or smoothies, or mix it into mayonnaise or mustard when making a sandwich.

Although flaxseed oil supplements are available, most experts agree that a dietary source is preferable for maximum benefits.
