Flaxseed is a good source of many nutrients, including protein, fiber, omega-3 fatty acids, thiamine, and copper.
Flaxseed is rich in ALA, a type of omega-3 fatty acid that may offer numerous benefits for heart health.
Flaxseed contains nutrients called lignans that may help decrease cancer growth. Some studies link this food to a lower risk of several types of cancer, but more research is needed.
