High-Mercury Fish

A diet should always include fish. It offers you a variety of vitamins and minerals in addition to being a good source of high-quality protein. Your baby's cognitive development depends on the rich omega-3 fatty acids (DHA and EPA) found in fish. Salmon also contains a lot of selenium, a mineral that is essential for the detox of heavy metals and the protection of the brain. Enzymes based on selenium may also lower the risk of preterm birth and pregnancy-induced hypertension.

A poisonous chemical called mercury, which can harm the nervous system, kidneys, and immune system may be found in high levels in some types of fish, making them best avoided while pregnant. Both fresh and canned fish that are high in mercury include shark, swordfish, king mackerel, and certain types of tuna (albacore, yellowfin, and bigeye). Low-mercury fish offer all of the great benefits of seafood without the toxicity risk. Anchovies, cod, salmon, and sardines are some examples of these kinds.
