    • Maternal exposure to Cadmium increase early delivery, which leads to a lower birth weight. 
    • You can eat up to 2 average meals a week of fish and shellfish that are lower in mercury, such as shrimp, salmon, pollock, catfish or canned light tuna (albacore -white- tuna has more mercury than canned light tuna).
