Question 1/17

Fresh fish is always healthier than frozen fish.

  • True
  • False

Unless you know for sure it's high-quality fresh fish, go with frozen. A lot of fish is flash frozen on the boat right after it's caught. After thawing, it should still be quite good.On the other hand, "fresh" fish that was never frozen may have spent a few days sitting in a smelly ship's hold by the time you buy it. And some "fresh" fish may have been frozen and then thawed out behind the supermarket counter.

Question 2/17

The health risks from eating fish often outweigh the benefits.

  • True
  • False

Many foods, from fruits and vegetables to dairy products and meat, can be tainted with chemicals and other unsavory things. Fish, too, can have mercury and PCBs. But experts say the benefits are much more likely to outweigh the risks.

Question 3/17

People who eat fish regularly have a lower risk of:

  • Heart disease
  • Stroke
  • Depression
  • All of the above

The benefits of regularly eating healthy fish keep piling up. It lowers blood pressure, cuts the risk of irregular heartbeats, and drops the risk of fatal heart disease by 36%.It also seems to lower the risk of stroke and some cancers, improve your mood, and help with other conditions, such as rheumatoid arthritis.

Question 4/17

Most of the health benefit of eating fish comes from:

  • Omega-3 fatty acids
  • Omega-6 fatty acids
  • Omega-9 fatty acids

Omega-3 fatty acids help our cells work. Because our bodies don't make enough of them, we have to get them in food. Fish that are high in omega-3 fatty acids include salmon, herring, mackerel, and sardines.

Question 5/17

Oysters raise libido.

  • True
  • False

Oysters as an aphrodisiac? It turns out to be a legend, or at least researchers have never found a connection.In theory, people who have very low levels of certain nutrients, like selenium, could feel friskier after eating more oysters. But that condition is rare.

Question 6/17

How many servings of fish per week does the American Heart Association recommend?

  • 1
  • 2
  • 3
  • 4

The American Heart Association recommends at least two servings of fish per week, especially fatty fish high in omega-3 fatty acids. What's a serving? About 4 ounces -- a little bigger than the palm of a woman's hand.

Question 7/17

"Sushi grade" raw fish is certified to be free of bacteria and parasites.

  • True
  • False

Bad news, sushi fans. No matter how good the restaurant, eating raw seafood poses a higher risk of food-borne illness than cooked seafood. Although "sushi-grade" sounds good, it's a marketing term. It has no legal meaning. Fish for sushi is often flash frozen, which should kill parasites. But the only sure way to avoid parasites and bacteria is to cook your fish.

Question 8/17

Which of the following usually has the lowest percentage of calories from fat?

  • Chicken
  • Scallops
  • Pork

Shellfish -- like crab, lobster, shrimp, scallops, and clams -- is quite low in fat. Compared to beef and chicken, shellfish tends to have higher levels of healthy fats and lower levels of unhealthy fats. Shellfish is a great source of protein, too.So break out your lobster crackers and put on your bib. Just go easy on the drawn butter.

Question 9/17

Eating fish can help your memory as you age.

  • True
  • False

Fish really might be brain food. Studies have found that eating baked or broiled fish once a week -- over the long term -- seems to help people keep their short-term memory sharp.Eating fish also appears to lower your risk of Alzheimer's disease and mental decline.

Question 10/17

Wild fish always have more omega-3 fatty acids than farm-raised fish.

  • True
  • False

It depends on the fish. Some fish, such as salmon, mackerel, herring, and trout, can be high in healthy omega-3s whether they're farmed or wild.  But a lot of farmed fish, especially tilapia, are fed a corn-based diet. As a result, they tend to have much lower levels of omega-3s.

Question 11/17

Fish is supposed to smell "fishy."

  • True
  • False

Fresh seafood should have a mild smell or none at all. If it smells sour or fishy, it's past its prime. If it stinks up your kitchen every time you open the refrigerator door, throw it out.Good fish should never be mushy either. It should be moist and springy when you touch it.

Question 12/17

It's better to get omega-3 fatty acids from fish than from fish oil supplements.

  • True
  • False

Stick with fish, not capsules. Most of the encouraging studies have looked at people eating fish, not taking a supplement. Extracted omega-3 fatty acids may not have the full benefits of what's naturally in fish.Some recent studies of people at higher risk of heart disease did not find that omega-3 supplements helped. People with heart disease should talk to their doctor to see if omega-3 supplements might be a good idea.

Question 13/17

Cooking fish properly will kill worms and other parasites.

  • True
  • False

Fish can carry some nasty parasites. One of the most revolting is the tapeworm. It can live in the human gut for years, growing up to a couple of yards long, causing severe pain, weight loss, and anemia.Want the good news? Cooking your fish so the internal temperature reaches 145 degrees Fahrenheit will kill any parasites.

Question 14/17

Pregnant women should not eat fish.

  • True
  • False

Pregnant women should eat fish -- up to 12 ounces of seafood per week. Fish has nutrients that are important for a baby's brain development. Studies show that pregnant women who eat fish regularly have children that go on to score higher on intelligence tests.However, pregnant women should avoid fish high in mercury, like shark, swordfish, tilefish, and king mackerel. Instead, choose varieties that are lower in mercury, like shrimp, canned light tuna, salmon, and catfish. Women who are pregnant or breastfeeding can eat white tuna (albacore), but only 6 ounces a week, because it's higher in mercury than light tuna.

Question 15/17

Seafood is the most common cause of food allergies.

  • True
  • False

Fish is in the top 8 most common food allergies. That includes shellfish and finned fish. Seafood allergies may develop suddenly in adulthood. Unfortunately, they don't tend to fade and can often be very serious. If you get a seafood allergy, you're probably stuck with it.

Question 16/17

Even fried fish is good for you.

  • True
  • False

Fish is healthiest when it's baked or broiled. Unfortunately, fish's health benefits may disappear once it's deep fried. Eating a lot of fried foods -- especially when cooked in saturated or trans fats -- is closely linked to heart disease and stroke. In one study of older women, a single serving of fried fish a week was associated with a 48% higher risk of heart failure.  Skip the fried fish. Choose baked or broiled instead.

Question 17/17

Fear of fish is called:

  • Aquaphobia
  • Ichthyophobia
  • Landlubberism

You know that eating fish is good for you, but what if you just hate it? Keep trying. Remember that seafood has all sorts of textures and flavors. Try a bland fish like tilapia or cod. Or try something with a firm, meaty texture, like swordfish or scallops. In time, you're bound to find seafood you like -- and your health will be better for it.
