Flax Seeds1

Flax seeds are small, nutrient-dense seeds from the flax plant (Linum usitatissimum), native to the Mediterranean region. They are typically consumed whole or ground, and can be pressed to extract flaxseed oil.

Flax seeds are often added to foods for their nutritional value, providing fiber and omega-3 fatty acids. They are commonly found in baked goods, cereals, plant-based milk alternatives, and veggie burgers, where they can also act as a binder.

Flax seeds are generally recognized as safe (GRAS) by the FDA. They are a good source of dietary fiber and alpha-linolenic acid (ALA), an omega-3 fatty acid. Some research suggests ALA may support heart health, though evidence is mixed. JECFA has evaluated flaxseed and its oil, establishing specifications for identity and quality. No significant controversies exist regarding their consumption at typical dietary levels.
