Flaxseed is commonly used to improve digestive health or relieve constipation. Flaxseed may also help lower total blood cholesterol and low-density lipoprotein (LDL, or "bad") cholesterol levels, which may help reduce the risk of heart disease.
One serving of flaxseed provides protein, fiber, and omega-3 fatty acids. It may help lower the risk of some cancers, help you maintain a moderate weight, and reduce cholesterol and blood pressure.
