The Real Reason You Should Avoid These Types Of Fish At Restaurants

Going out to eat is a fun way to try new foods that you wouldn't normally make at home. Many people still try to make healthy decisions when eating out, and some of the healthiest meals you can order at a restaurant contain fish. Fish is generally considered to be a healthy protein. However, not every type of fish is good for you. According to The Healthy, you should avoid both yellowfin and bluefin tuna at restaurants.

A 2017 study found that yellowfin tuna can carry up to 36 times more pollutants than other kinds of tuna. These pollutants include things like flame retardants, pesticides, and polychlorinated biphenyls (PCBs). Albacore and skipjack tuna are two good alternatives that do not contain as many pollutants. While bluefin tuna isn't known for being particularly harmful, this species of fish is currently threatened by overfishing. You should avoid this type of fish in order to let the species recuperate. Instead, order albacore tuna belly. This fish has a rich flavor similar to bluefin tuna but is more sustainable.

It is recommended that adults eat about eight ounces of fish each week (via US Food & Drug Administration). Fish is a lean protein that helps your body support healthy muscles, bones, and tissue. According to Good Housekeeping, fish is a great source of omega-3 fatty acids, calcium, and vitamin D. Eating fish regularly has been shown to improve heart health, decrease the risk of some bone fractures, and aid in cognitive development.

Some of the healthiest types of fish you can eat include salmon, cod, mackerel, and sardines. Salmon is a great source of omega-3 fatty acids and calcium (via Everyday Health). Choose wild-caught salmon when possible, which usually contains fewer contaminants than farm-raised salmon. Sardines are also high in omega-3 fatty acids, as well as vitamin D and calcium. Cod is high in lean protein, phosphorus, niacin, and vitamin B12 (via Healthline). Finally, mackerel is full of healthy fats. However, you should avoid king mackerel, as this type of fish is often high in mercury.
