for me, i will option for
1. skip Salmon except u can find wild. cause high in pesticide, PCBA and etc.
2. Skip all big fish as may have higher mercury content.
3. Go for ikan bilis, the smaller the fish is, the lesser the mercury and etc.
4. Moderate at every food.
5. You can find canned sardine. That sardine is tiny and wild catch that dip in Olive oil. This option is expensive, cause those sardines cost more than rm10 per tiny can.
