Fish and shellfish are among the most nutritious protein sources, but most Americans don’t consume enough. Here’s all you need to know about the benefits of consuming fish and shellfish, how much you should have, and how to choose the best sources. Then keep reading for ideas on incorporating seafood into your routine.
Seafood, Omega-3 Fats, and Your Health
Fish and shellfish are sources of omega-3 fats called eicosapentaenoic acid, or EPA, and docosahexaenoic acid, or DHA. These fats are types of unsaturated fatty acids that may have health benefits.
The Dietary Guidelines for Americans suggest getting about 12 ounces of seafood a week from various sources, but most Americans fall short. The average American gets less than half of the recommended amounts, and about half of Americans say they rarely or never eat seafood.
Mayo Clinic lists these benefits for heart health.
- Reduced overall inflammation
- Lower triglyceride levels
- Reduced risk for stroke
Consuming EPA and DHA from seafood may also help support blood sugar regulation.
Fatty fish are highest in EPA and DHA. Here are some examples.
- Salmon
- Trout
- Flounder
- Herring
- Sardines
- Anchovies
- Tuna
Fish and shellfish are rich in other nutrients, too. They may have B vitamins, potassium, and antioxidants like astaxanthin. They’re low in saturated fat. Although some species, like shrimp, are high in cholesterol, most people can consume them if their overall diet is low in saturated fat. Ask your doctor if you’re concerned.
Fish and shellfish may support weight control because they are high in protein and low in carbohydrates and calories. Even fatty fish are lower in calories than protein sources like fatty red meat.
Seafood and Environmental Sustainability
When talking about consuming seafood, sustainability is a common concern. The environmental impact of seafood varies widely, according to the article in the Journal Nutrition. Factors that impact sustainability include how abundant the species is, whether the species is farmed or caught wild, what fishing method is used, and where the species is grown and caught.
You can support the environment by checking resources like the Seafood Profiles from the National Oceanic and Atmospheric Administration (NOAA) or Seafood Watch from Monterey Bay Aquarium.
What About Mercury and PCBs?
Mercury is an environmental contaminant that can be a health concern for some people who consume seafood. Mercury can be stored in fish fat in the form of methylmercury. When you consume it, methylmercury can build up in your body’s fat. Methylmercury levels are higher in large fish with a lot of fat.
The Dietary Guidelines for Americans suggest avoiding shark, tilefish, swordfish, and king mackerel to avoid the highest levels of mercury. Pregnant women and children should also avoid or limit canned tuna. Salmon, anchovies, sardines, and trout are among the most nutritious species with a low amount of methylmercury. Tilapia, shrimp, and flounder are other low-mercury options.
Polychlorinated biphenyls (PCBs), dioxins, and pesticide residues are also examples of environmental contaminants that can make their way into seafood. There have been investigations into the potential for these chemicals to cause cancer, but the effects aren’t clear. What is clear, according to the Harvard School of Public Health, is that the cardiovascular benefits of regular seafood consumption are far more likely to outweigh cancer or other health risks.
Plant-Based Sources of Omega-3 Fats
Some people don’t eat much seafood because they haven’t found many types that they like. There are plant-based sources of omega-3 fats.
Here are some sources.
- Flaxseed and flaxseed oil
- Walnuts
- Canola and soybean oils
- Chia seeds
The omega-3 fats in these sources are in the form of a type of fat called alpha-linolenic acid, or ALA. Your body can convert some ALA to EPA and DHA, but only a limited amount. There may be additional health benefits to consuming EPA and DHA from seafood compared to relying solely on high-ALA plant-based foods for your omega-3 fats.
Fish Oil Pills and Other Omega-3 Supplements
Various types of omega-3 supplements are widely available. Common forms include fish oil capsules and gels, ALA supplements, and capsules with EPA, DHA, and ALA. However, research hasn’t shown the same benefits of taking supplements compared to eating seafood. Plus, supplements aren’t well-regulated and aren’t always pure. Ask your healthcare provider if you’re curious about omega-3 or other supplements.
Try These Strategies If You Don’t Like Seafood
There’s still hope if you want to consume seafood. There are many different types of fish and shellfish to try and various ways to prepare them.
Here are some strategies for finding seafood that you like.
- Keep trying different species. They have different tastes and textures. White fish like tilapia may be less “fishy” than other types of fish
- Try recipes with a variety of spices. They may alter the taste of the seafood in ways you enjoy
- Lemon is a common accompaniment to fish. Give it a try to see if it makes the fish taste better to you
- Bury fish and shellfish in salads, stews, casseroles, and patties
- Order fish or shrimp when you eat at a restaurant. That way, you’re getting a professional chef to prepare it for you, and you may enjoy it more than if you cook it for yourself at home
- Transform less-healthy methods of preparation into healthier ones. For example, make baked fish sticks with whole-grain bread crumbs instead of using fried fish sticks, or make tuna salad with avocado or Greek yogurt instead of mayonnaise.
It can also be a good idea to think about why you don’t like seafood. If you’re forming your opinion based on an unpleasant childhood memory, for example, it may be time to reconsider. Your taste buds may have matured, or you can try a different type of fish or preparation method.
Incorporating Seafood into Your Routine
Here are some ideas for nutritious meals and snacks with seafood that are easy to make.
- A frozen salmon burger patty, or make your own patty with canned or fresh salmon, whole-grain breadcrumbs, egg white, and chopped vegetables, served on a whole-grain hamburger bun with baked kale chips with olive oil and sea salt
