guess what major food source Americans still fall way short on in their diets?
If you said fish, winner, winner, seafood dinner. The average American eats
only a third of the recommended eight ounces of seafood per week, according to
the USDA. And that means we’re missing out on all the nutritious stuff
seafood has on offer: lean protein, vitamin D, selenium, and brain-boosting,
I don’t think people eat enough fish simply because they don’t know how to cook
it,” says Keri Gans, R.D., author of The Small Change Diet.
there could be another culprit: concerns about mercury. This
naturally-occurring mineral can be toxic in high levels, and it tends to hang
around in your body, so pros recommend limiting consumption of fish that
contain a lot of it. Pregnant or breastfeeding women are warned to watch their
intake because high levels of mercury can damage the developing brain
and nervous system of a fetus or baby, but small children and any woman of
childbearing age should be concerned as well.
Gans says, avoiding seafood all together is a bit extreme—and unnecessary.
“There are way more fish that are low in mercury than high in mercury,” she
says, such as salmon, flounder, lobster, and cod. (Check out this list of
low-mercury fish fromthe FDA to see the full range of options). Big-game fish
such as swordfish, bigeye tuna, marlin, orange roughy, shark, and king mackerel
tend to have the most mercury, since they eat other mercury-containing fish.
the mercury risk of fish may be a little overhyped. A 2013 study found
that seafood accounted for only 7 percent of the mercury in women's bodies. And
dietary recommendations seem to be changing, too. The FDA and EPA actually
recommend that pregnant women eat more cooked
seafood to reap the nutritional benefits found in fish for their developing
child. The benefits seem to outweigh the risks.
line: We could all stand to eat more seafood, says Gans. "I suppose you
could eat fish every day as long as your choices are low in mercury," she
says, although she recommends a "varied diet" to get a wide range of
nutrients. Gans says she follows the American Heart Association's
guidelines of at least two 3.5-ounce servings a week. (For higher-mercury fish,
such as canned tuna, you can have maximum one serving a week, per FDA
recommendations). If you're pregnant, stick with the FDA's
recommendation of two to three servings of low-mercury fish per week to
reap those important developmental benefits.
