Some fish can sabotage pregnancy, but other kinds of fish can improve fertility!
Avoid seafood high in mercury and bacteria. Your body easily absorbs mercury from fish and stores it for months. Once you become pregnant, the mercury in your body will cross the placenta. Studies show that exposure to high concentrations of methylmercury during pregnancy can impair a baby's growing brain and nervous system. The results may be mild or severe. Cognitive skills (like memory and attention), language, motor skills, and vision may be affected.
- Raw Sushi which may contain parasites or bacteria
- Lox and other refrigerated smoked seafood due to bacteria risk
- Raw Shellfish, such as oysters and clams as may contain Vibrio bacteria
- Swordfish, King Mackeral, Shark, Tilefish, Golden and White Snapper due to high levels of mercury
But, you should still eat fish!
The omega-3 fatty acids found in fatty fish such as salmon, sardines, and herring have fertility-boosting benefits. They may help to regulate reproductive hormones, increase blood flow to reproductive organs, and reduce the inflammatory process in blood. Studies show that babies who get adequate amounts of omega-3 fatty acids during pregnancy have better cognitive development and vision than babies who receive fewer omega-3s. You can also get omega-3 fatty acids from other foods such as walnuts, pumpkin seeds, and enriched eggs. If you don’t eat enough fish, take omega-3 supplements (read more about Omega 3's.)
Eat up to 12 ounces a week of fish (roughly 2 entrees) that are lower in mercury, such as:
- Canned light tuna (no more than 6 ounces a week)
