DIANE SAWYER (ABC NEWS)(OC): We have news about "Healthy
Living" tonight, a big headline about one of the most popular dietary supplements
in the country. The American Heart
Association has long said that eating oily fish
is good for your heart. So millions of
people take
fish oil supplements hoping
for the benefit, and, in fact, doctors
often recommend the supplements for people who already have heart disease. But a big new study
out tonight says those pills are not
doing what they thought and here's ABC's Dr.
Richard Besser.
NARRATOR (COMMERCIAL): Fish oil may
support heart health.
NARRATOR (COMMERCIAL): Promotes a
healthy heart.
NARRATOR (COMMERCIAL): Omega 3 supports
a healthy heart.
DOCTOR RICHARD BESSER (ABC NEWS)(VO):
$740 million, that's how much we spend on them a year. Fish oil capsules, containing the substance
heart doctors
swear by, omega-3 fatty acids. Look at the bottles, the packaging says the
capsules support a healthy heart, may reduce the risk of coronary
heart disease. But today, that groundbreaking
new study says the proof is in and fish oil capsules don't deliver
on their promise.
DOCTOR RICHARD BESSER (ABC NEWS)(VO):
Researchers looked at 20 studies on heart health, almost 70,000 patients
altogether.
DOCTOR RICHARD BESSER (ABC NEWS)(VO):
And say that overall people who took fish oil supplements died of heart disease
or stroke at the same rate
as anybody else. In short, no proven benefit.
DOCTOR HARLAN KRUMHOLZ (YALE SCHOOL OF
MEDICINE): There's a lot of claims that are made about a lot of diets and
supplements that just don't have the evidence behind them.
DOCTOR RICHARD BESSER (ABC NEWS)(VO):
But eating fish itself that seems to help.
People who eat fish twice a week are less likely to have heart disease
and less likely to die from it. It's not
clear why getting
omega-3s in food
not pills makes a difference but it
looks like it does. One theory, that the
body absorbs the omega-3s from fish in different way. Another, people who eat fish do other healthy
things, as well. So if you're spending
your money to take fish oil capsules to protect your heart, it may be better to
put
that money towards a nice piece of salmon.

York.
DIANE SAWYER (ABC NEWS)(OC): And Rich
is here now. You're always warning us,
cautioning us about those supplements.
DOCTOR RICHARD BESSER (ABC NEWS)(OC):
That's right. You know, I am, because very little about supplements is proven
because unlike drugs, it doesn't have to be.
If you look at the bottle and you look at any health claim, there's a little
asterisk after the claim and here's what it says on the back.
DOCTOR RICHARD BESSER (ABC NEWS)(VO):
"These statements have not been evaluated by the Food and Drug
Administration. This product is not
intended to diagnose, treat, cure or prevent any disease."
DIANE SAWYER (ABC NEWS)(OC): All they
need to prove is that it's safe, not that it works. And so I tell people to try and get
their nutrition through food.
Unless your doctor tells you have a true nutritional deficiency, in my
opinion this is not a good use of people's money.
