Even during the “fat-free diet” days of the 1990s, nutritionists
have pointed out that not all fats are unhealthy and that the “good”
types of fat include omega-3 fatty acids. Fatty acids are the building
blocks of fat, which, despite its misunderstood reputation, is a vital
The benefits of omega-3 fatty acids are well-known. Omega-3s are used to
regulate blood clotting, build cell membranes and support cell health.
They curb inflammation and may help to prevent coronary disease, Alzheimer’s
disease, and depression. Higher levels of omega-3s in the blood have been
associated with increased longevity. And omega-3s are polyunsaturated,
which is the heart-healthy kind of fat that helps to reduce blood triglycerides
and low-density lipoprotein (LDL), the so-called “bad” cholesterol.
Your body cannot make omega-3 fatty acids--you have to eat them. The typical
American doesn’t dine on many foods that are rich in omega-3s. Whenever
possible, you should try to get your omega-3 fatty acids from eating foods
rather than taking supplements.
Here are five foods that will put more omega-3s into your daily diet:
The best source of the essential omega-3 fatty acids DHA and EPA is fish,
and some fish deliver a higher dose than others. The top choices are salmon,
mackerel, herring, lake trout, sardines, anchovies, and tuna. The American
Heart Association recommends that you eat at least two servings of fish
per week. A serving is considered 3 1/2 ounces of cooked fish or 3/4 cup
of flaked fish.
As with people, it seems that fish are what they eat. That's important
to remember when comparing omega-3 in farmed fish with that in wild-caught
fish. Wild-caught fish are excellent natural suppliers of omega-3 when
their diet consists of algae and other fish, as are farmed fish that eat
fish meal or algae supplements. Like cattle, however, some farm-raised
fish are fed mostly grains and soy, a diet that causes their flesh to
contain more short-chain ALA omega-3s and less long-chain EPA and DHA
omega-3s. Your body needs both short-chain and long-chain omega-3s, but
the long-chain variety provides most of the anti-inflammatory benefits.
Pasture grass is a very good source of omega-3s. So when cattle or other
land animals eat a grass-based diet, their meat ends up being a tremendous
source of the desirable fatty acids. Similarly, milk, cheese, yogurt,
and eggs obtained from grass-fed or pasture-fed animals are generally
going to be your best source for omega-3s derived from dairy rather than meat.
This delicious pod vegetable is not merely a pre-sushi appetizer: Edamame
(soybeans) are also an amazing source of omega-3s. They are one of the
most well-rounded healthy snacks because they are filled with both fiber
(9 grams) and protein (11 grams), on top of the 1/3 g of omega-3s per
half-cup serving shelled. Reach for a handful of edamame instead of peanuts
the next time you sit down to watch TV.
Eating flaxseed oil is not the same thing as eating the flaxseeds themselves.
Flaxseeds are a good way to get fiber, but you should use flaxseed oil
if you want omega-3s. Since the oil is a condensed product of the seeds,
you get more omega-3s in the oil. Flaxseed oil is a terrific plant source
of ALA omega-3s and it's the only culinary oil that beats canola oil
in omega-6 to omega-3 ratio. However, it has a low smoke point, so it’s
less suitable for frying and better suited for use in fresh recipes such
as salad dressings or pesto.
Of all the nuts commonly available, walnuts are the omega-3 champs. A quarter-cup,
196-calorie serving of walnuts provides 113% of your daily value of omega-3s,
the most significant amount of omega-3s in any nut. In fact, flaxseed
is the only plant food that is denser in omega-3 fats per serving. So
break out the nutcracker and pop a few in your mouth or sprinkle halved
walnuts on a salad.
