Flaxseed is a small, brown or golden seed that comes from the flax plant. It is known for being a rich source of omega-3 fatty acids, which are essential for heart health. Flaxseed is also packed with fiber, making it a great addition to a balanced diet. People often add it to smoothies, oatmeal, or baked goods to boost their nutritional value. In addition to its health benefits, flaxseed is often used in vegan cooking as an egg substitute. When mixed with water, it forms a gel-like consistency that can help bind ingredients together. This makes it a popular choice for those looking to reduce animal products in their meals.
