Remember those chia pets we used to grow in middle school? Who would have thought, now we enjoy them in a delicious morning smoothie?? Despite their small size, chia seeds are an excellent source of omega-3 fatty acids, rich in antioxidants, fiber, and calcium. They have about six times more calcium than milk. They are loaded with nutrients that can have important benefits for your body and brain. They are commonly referred to as a modern day superfood.
