Flaxseed is a plant-based food that provides healthful fat, antioxidants, and fiber. Some people call it a “functional food,” which means that a person can eat it to boost their health.
Today, flaxseed is available in the form of seeds, oils, powder, tablets, capsules, and flour. People use it as a dietary supplement to prevent constipation, diabetes, high cholesterol, heart disease, cancer, and several other conditions.
