Golden flax, also known as linseed, is cultivated for its seeds, fiber, and flax oil. Nutrient-dense, the seeds contain essential fatty acids, including omega-3 and omega-6, iron, calcium, potassium, fiber, and 6g of protein per three tablespoons of serving. For a delicious nutty flavor packed with benefits, add them to baked goods and smoothies or sprinkle over yogurt and oatmeal.
