Flax seeds are incredibly nutritious and are particularly rich in omega-3 fatty acids, specifically alpha-linolenic acid (ALA). They are also an excellent source of dietary fiber, both soluble and insoluble, which aids in digestion and promotes gut health. Additionally, flax seeds are packed with lignans, which are plant compounds with antioxidant properties. They also contain protein, vitamins (such as B vitamins and vitamin E), and minerals (such as magnesium, manganese, and phosphorus).
