Chia seeds are nutritional powerhouses, boasting high levels of omega-3 fatty acids, fiber, protein, and vitamins. Originally from Central America, gluten free chia seeds come in two varieties: Black and white. However, there is little difference between the two. Chia seeds can be sprinkled raw on top of oatmeal, smoothies, yogurt, pudding, or salads. When ground into a flour, chia is a great option for vegan baking.
