Why They're a Good Fat
Not
all fats are unhealthy. Omega-3 fatty acids are one of the "good" types
of fat. They may help lower the risk of heart disease, depression,
dementia, and arthritis. Your body can't make them. You have to eat them
or take supplements.
Know the 3 Types of Omega-3s
Omega-3
fatty acids come in more than one form. The types found in fish, called
DHA and EPA, seem to have the strongest health benefits. Another form
known as ALA is found in vegetable oils, flaxseed, walnuts, and dark
leafy vegetables such as spinach. The body can change a small amount of
ALA into EPA and DHA, but not very well.
How Omega-3s Fight Disease
Omega-3
fatty acids help your heart in several ways. They curb inflammation in
the blood vessels (and the rest of your body). At high doses they also
make abnormal heart rhythms less likely and lower your level of blood
fats called triglycerides. Finally, they can slow plaque buildup inside
the blood vessels.
Heart Disease
The
American Heart Association recommends 1 gram a day of EPA plus DHA for
people with heart disease. Eating oily fish is best, but your doctor
might recommend a fish oil capsule. If you've had a heart attack, a
prescription dose of omega-3s may help protect your heart. Some studies
show fewer heart attacks and fewer heart disease deaths among heart
attack survivors who boosted their levels of omega-3.
Helping Your Heart's Rhythm
Omega-3s
seem to have a stabilizing effect on the heart. They can lower heart
rate and help prevent arrhythmias (abnormal heart rhythms). Several
common sources of omega-3s are fish, walnuts, broccoli, and edamame
(green soybeans that are often steamed and served in the pod).
Cutting Triglycerides
Omega-3s
DHA and EPA can lower your triglycerides, a blood fat that’s linked to
heart disease. Talk with your doctor before taking omega-3 supplements,
because some types can make your "bad" cholesterol worse. You can also
bring down triglyceride levels by exercising, drinking less alcohol, and
cutting back on sweets and processed carbs like white bread and white
rice.
Lowering High Blood Pressure
Omega-3s
can help lower blood pressure, a bit. One plan is to replace red meat
with fish during some meals. Avoid salty fish, such as smoked salmon. If
you have high blood pressure, limiting salt is probably one of the
things your doctor has recommended.
Prevent Stroke?
Omega-3
foods and supplements curb plaque buildup inside blood vessels, helping
with blood flow. So they may help prevent stroke caused by clots or a
blocked artery. But at high doses, omega-3 supplements might make
bleeding-related stroke more likely; so check with your doctor.
Useful for Rheumatoid Arthritis
Studies
suggest omega-3s can curb joint pain and stiffness in people with
rheumatoid arthritis. A diet high in omega-3s may also boost the
effectiveness of anti-inflammatory drugs.
May Help With ADHD
Some
studies suggest omega-3 supplements may ease the symptoms of ADHD.
Omega-3 fatty acids are important in brain development and function.
Omega-3s may provide some added benefits to traditional treatment, but
they don't replace other treatment.
Research on Dementia
The
jury is still out, but there's some evidence that omega-3s may help
protect against dementia and age-related mental decline. In one study,
older people with a diet high in omega-3 fatty acids were less likely to
get Alzheimer's disease. More research is needed to confirm the link.
Omega-3 Supplements
If
you don’t like fish, you can get omega-3 from supplements. One gram per
day is recommended for people with heart disease, but ask your doctor
before starting. High doses can interfere with some medicines or
increase risk of bleeding. You may notice a fishy taste and fish burps
with some supplements. Read the label to find the amounts of EPA, DHA,
or ALA you want
Vegetarian Sources of Omega-3s
If
you don't eat fish or fish oil, you can get a dose of DHA from algae
supplements. Algae that is commercially grown is generally considered
safe, though blue-green algae in the wild can contain toxins.
Vegetarians also can get the ALA version of omega-3 from foods such as
canola oil, flaxseed, walnuts, broccoli, soy products and spinach -- or products
fortified with omega-3s.
Avoid the Omega-3 Hype
Many
food products now boast that they have added omega-3 to support various
aspects of your health. But be aware that the amount of omega-3 they
contain may be minimal. They may contain the ALA form of omega-3, which
hasn't yet shown the same health benefits as EPA and DHA. For a measured
dose of omega-3, taking fish oil supplements may be more reliable.
