How Often Should I Eat Fish


How Often Should I Eat Fish? The benefits of eating fish are just too good to ignore. Packed full of high-quality protein, healthy fats and various vitamins, fish contains everything your body needs. However, due to health concerns surrounding mercury contamination in large fish, it can be difficult trying to work out how often you should eat fish. Fret not – we’ve got the low-down on everything you need to know about eating fish.

How Often Should I Eat Fish

It’s the omega-3 fatty acids, which are plentiful in many types of seafood, that probably confer most of the heart benefits of eating fish. “Omega-3s are important for cell-to-cell signaling in heart muscle and for cells within the lining of the arteries,” Rimm says. They reduce inflammation, help prevent heart rhythm abnormalities, improve the flexibility of arteries, and help lower cholesterol.

The guideline authors looked at the positive effects of omega-3s on cardiovascular health by examining data from numerous observational studies and randomized controlled trials. Among the main conclusions are:

  • Those who consume one fatty fish meal per week had a 50% decreased risk of sudden cardiac mortality than those who consume little to no seafood.
  • Compared to individuals who ate little or no fish, those who ate one serving of fish per week had a 14% decreased risk of ischemic stroke (the kind brought on by a blood clot in the brain).

• Those who consumed seafood four or more times a week had a 22 percent lower risk of coronary heart disease overall vs. those who ate it less than once a month.

Fish vs. Fish Oil Pills

If you dislike seafood, you might wonder if you can get the same advantages by taking a tablet instead.

The American Heart Association (AHA) issued a scientific guideline on this subject last year, advising those who have experienced a heart attack or have been given a heart failure diagnosis to take omega-3 supplements.

However, the authors came to the conclusion that taking fish oil supplements didn’t help anyone else prevent heart attacks, strokes, or heart failure based on the available research.

The benefits of fish may be at least partially attributed to the presence of omega-3 fatty acids, but they may also result from the substitution of fish for foods high in saturated fat, such as steak, according to Lichtenstein. “Making healthier dietary choices in addition to taking a supplement”

Is More Fish Better?

It’s possible that going beyond the recommended two servings a week could provide additional health benefits. But hard evidence is lacking. “There just aren’t a lot of studies that included consumption at higher levels,” Rimm says.

Based on the available evidence, the researchers concluded that much of the benefit comes from moving from very little or no fish in the diet to eating fish once or twice a week. “However, if fish is consumed four or more times a week as a substitution for other less healthy foods, then I do think that more is better,” Rimm says. 

Choose Low-Mercury Fish

One drawback of eating more fish is the possibility of being exposed to mercury, a toxin that can harm the health of adults as well as fetuses and young children when consumed in excess. Mercury can also disrupt brain development in fetuses and young children.

While everyone should eat fish to improve their heart health, women of childbearing age (particularly those who are pregnant or breastfeeding) and children are urged to do so in order to obtain the omega-3 fatty acids that promote developing brains.

“Eating fish is healthful, and you can consume a lot of fish. Simply pay attention to which fish are high or low in mercury, advises Jean Halloran, head of food policy projects at Consumers Union, Consumer Reports’ lobbying arm. Even for adults, excessive mercury exposure poses acute neurological hazards, including mental fogginess, tremors, and balance loss.

The AHA advises people to seek fatty fish with the highest omega-3 content for their two weekly portions. Salmon, mackerel, herring, lake trout, sardines, and albacore tuna are on the list.

The Food and Drug Administration’s recommendations for children and women of childbearing age, however, conflict with several of those suggestions. Albacore tuna is recommended by the FDA as a “once a week choice.” And while King mackerel is a high mercury fish that the FDA advises avoiding, Atlantic mackerel is low in mercury and safe to consume two or more times each week.

The authors of the AHA advice concluded that the benefits of eating fish twice a week exceed any concerns, especially if you consume a variety of seafood, and did not discover any evidence that mercury had any negative effects on cardiovascular disease. However, Rimm points out that they did not examine youngsters or expectant mothers in their analysis of the literature.

Consumer Reports advises eating low-mercury seafood to get your omega-3s. Fortunately, several of these—Atlantic mackerel, sardines, salmon (especially tinned salmon), and trout—are excellent providers of omega-3s. Even though other low-mercury fish like tilapia, catfish, flatfish, and sole don’t contain as many omega-3s, they do contain some, according to Halloran.

Halloran notes that earlier Consumer Reports tests of mercury levels in tuna show that pregnant women shouldn’t consume it at all. Tuna is the second most popular form of seafood after shrimp. Everyone else should avoid eating solely tuna and instead choose chunk light, which has one-third the mercury of albacore and around one-fifth that of sushi tuna (such as bigeye).

One of the biggest reasons that people are concerned about regularly eating fish is the fact that some types of seafood contain measurable amounts of mercury. Mercury is a toxic substance that can contribute to illness and neurological disease, and it’s especially dangerous for pregnant women and young children. Fish do not produce mercury on their own, but ingest trace amounts that have leaked into oceans, lakes and other waterways from mercury dumps and burning fossil fuels.

While most types of seafood don’t contain enough mercury to cause any harm, pregnant women, children under six and those who are concerned with their mercury consumption should avoid eating king mackerel, marlin, swordfish, bigeye tuna, or ahi tuna.

Concerned About Mercury?

The fact that some forms of seafood contain detectable levels of mercury is one of the main causes of people’s concerns about frequently eating fish. Mercury is a hazardous metal that can cause illness and neurological disorders. Pregnant women and young children are particularly vulnerable to its dangers. Fish do not naturally manufacture mercury; instead, they consume trace amounts that have escaped from mercury dumps and the burning of fossil fuels into the world’s oceans, lakes, and other waterways.

While the majority of seafood doesn’t contain enough mercury to be harmful, pregnant women, kids under six, and others worried about their mercury intake should stay away from eating bigeye or ahi tuna, king mackerel, marlin, or swordfish.
