The New Low-Cholesterol Diet: Fatty Fish
The right fish can do wonders for your heart.
The term "fatty fish" may sound unappealing, but actually these are
the tastiest and healthiest foods from the sea. Oily fish such as salmon, tuna,
sardines, mackerel, and trout are full of omega-3 fatty acids -- good fats
unlike the bad saturated fat you find in most meats. These fish should be a
staple of everyone's heart-healthy diet.
How Does Fish Help?
Omega-3 fatty acids have been shown to lower triglycerides, which are a type
of fat in the bloodstream. Experts aren't sure of the exact mechanism. Omega-3
fatty acids may also slow down the growth of plaques in the arteries and reduce
inflammation throughout the body.
What's the Evidence?
A number of studies going back years have shown the benefits of fatty fish.
In an important review of studies, researchers found that getting daily omega-3
fatty acids from fish oil could lower triglyceride levels by 25%-30%. The
results were published in The American Journal of Clinical Nutrition in
Based on the mounting evidence, the FDA approved a new "qualified health
claim" for the effects of omega-3 fatty acids ( EPA and DHA) for reduced risks
of coronary heart disease. It also allows the makers or distributors of foods
that contain these omega-3 fatty acids to advertise that the product may
reduce the risk of heart disease.
Getting Fatty Fish Into Your Diet
Fatty fish typically are cold-water fish. You have many good choices when it
comes to fatty fish. The American Dietetic Association recommends:
Three ounces of salmon alone offers about 1 gram of EPA and DHA. If
these fish aren't to your taste, you can also try white fish such as
halibut or trout. A 3.5-ounce serving
of trout offers about 1 gram of EPA, plus DHA.
One important point to keep in mind: How you prepare the fish is almost as
important as which type of fish you eat.
"The way that you prepare any of these foods makes a big difference in
your blood cholesterol level," says Keecha Harris, DrPH, RD, a spokeswoman
for the American Dietetic Association (ADA.) "It's always best to broil,
grill, or steam these foods."
