Despite their small size, chia seeds are full of important nutrients. They are an excellent source of omega-3 fatty acids, rich in antioxidants, and they provide fiber, iron, and calcium. Omega-3 fatty acids help raise HDL cholesterol, the “good” cholesterol that protects against heart attack and stroke.
Dry chia seeds can also be added whole or ground to smoothies and juices, mixed into yogurt or oatmeal, or sprinkled on top of a salad. If you're adding the seeds to a drink or a "wet" dish like oatmeal, they'll swell up slightly while you eat, but they'll retain a slight crunch.
