Why Fish Is More Than Just for Shabbat: The Benefits of Eating Fish

Mercury is a toxic metal found in sea water, and at high levels, it can cause harm. Mercury primarily impacts the nervous system, particularly in women before childbirth. Fetal exposure to mercury is linked to decreased brain function and even motor skills. Despite the presence of mercury in fish, they shouldn't be removed from our diet. You can choose fish that contain a small amount that the body can handle.

The smaller the fish, the less mercury it contains.

Not all fish are equal in nutritional value. Northern sea fish, which live in cold waters, are rich in omega-3 unsaturated fatty acids that participate in anti-inflammatory processes in the body, improve blood circulation, lower triglycerides, balance the ratio between good and bad cholesterol, and benefit heart health.

Sea fish contain iodine, which is found only in saltwater. Iodine is an important and essential mineral for thyroid function, which is responsible for metabolism in the body and for proper growth and development. In contrast, fish raised in ponds do not contain iodine because the water is low in salts.

Northern sea fish also contain selenium, niacin, and vitamin B12.

Recommended sea fish include cod (merluza), sole, mackerel, herring, grouper, sea bass, and salmon.

Tuna also contains omega-3 and iodine, but it's a very large fish that contains a lot of mercury. For this reason, it's recommended to eat tuna once every two weeks due to its high mercury content.

The less recommended fish are tilapia, carp, and Nile perch.

Nile perch is a large, predatory fish that grows in the sea but in warm areas. It is high in fat and does not contain essential omega-3 fatty acids, so it has no advantages and is not recommended.

Frozen fish patties contain 30% fish, with the rest being starches, sugar, preservatives, and other unknown substances. Also, processed fish schnitzel sold frozen contains a small amount of fish and is fried; therefore, they are not recommended.

It is advisable to eat fish not only on Shabbat. Even frozen fish from the northern sea, frozen at sea on ships, are good fish. Freezing does not affect their nutritional value.
