Omega-3 fatty acids are essential for a baby’s brain development. Most people choose to meet their daily requirements by consuming salmon or fish oil supplements. The mercury content in fish tends to make most pregnant women skeptical, so chia is a great alternative. For such a tiny seed, chia is quite high in omega-3 fatty acids. Typically, nuts and seeds with high fat content have short shelf lives before they turn rancid, but chia seeds are so rich in antioxidants they can be kept in storage for up to four years without deterioration.
