Flaxseeds (also known as linseeds) have been consumed for at least 6,000 years, making them one of the world’s first cultivated superfoods. Flaxseeds contain anti-inflammatory omega-3 fatty acids, although not the same type that fish do. Benefits include helping with digestion, skin, cardiovascular improvements, cholesterol and aid with sugar cravings. Flax is one of the richest sources of plant-based omega-3 fatty acids, called alpha-linolenic acid in the world. Another unique fact about flaxseeds is that they are a primary source of lignans in the human diet and contain about seven times as many lignans as the closest runner-up, sesame seeds.
