Flax seeds, also known as linseeds, are small brown seeds that come from the flax plant. They have a nutty flavor and are rich in nutrients such as omega-3 fatty acids, fiber, and lignans. Flax seeds can be ground into meal or used whole to add texture and crunch to baked goods, salads, and other dishes. They have also been known for their health benefits, including promoting digestive health, reducing inflammation, and lowering cholesterol levels.
