Omega-3 fatty acids —
essential to health and happiness
by Marcelle Pick, OB/GYN NP
Almost every woman I see in my practice is worried about fat. After years of misleading
media conditioning, it’s no wonder we remain convinced that eating fat will
make us fat. But in all honesty, extreme
low-fat diets don’t help regulate our weight or enhance our health.
In fact, a shortage of fat makes us significantly less healthy, and sometimes even
Our culture is beginning to wake up to how essential fats are to our survival —
especially omega-3’s. I’m sure you’ve seen the phrase “Good
source of Omega-3’s” stamped on food packaging in your grocery store.
From eggs to waffles, food manufacturers are figuring out that omega-3 fatty acids
sell. But many women are confused about why they are so good for us, especially
since we’ve been avoiding fat for all these years.
Studies have shown that omega-3 fatty acids can have a positive impact on or prevent
serious degenerative illnesses like heart disease, hypertension, rheumatoid arthritis,
Alzheimer’s, diabetes and more. The anti-inflammatory properties of omega-3’s
are especially beneficial to menopausal women in preserving heart, breast and bone
health, and even help keep our moods on an even keel.
I admit, it almost sounds too good to be true. But it is true. Over the years, I’ve
seen omega-3’s — referred to as essential fatty acids —
do wonders for women. They contribute to every inch of our bodies. From our hearts
to our minds and every cell in-between, I promise omega-3’s are the healthiest
fats you can consume! And no matter how busy you are, there are easy ways to include
them in your diet.
Let’s take a closer look at omega-3 fatty acids and how they can work for
What’s so essential about essential fatty acids?
Many of my patients want to know the difference between regular fat and “essential”
fat. Put simply, our bodies cannot make essential fatty acids (EFA’s)
on their own, so they must come from our diets. What’s more, both forms of
EFA’s (omega-3 and omega-6) are found in the membranes of every cell in our
At the molecular level, EFA’s protect and keep our cardiovascular, musculoskeletal,
GI and immune systems functioning optimally. They help insulate our nerve cells
and produce molecular messengers involved in immunity and the central nervous system.
We can obtain omega-3 and omega-6 fatty acids from a range of food sources. Here
are some good sources for these special fats. (Many foods have both omega-3’s
and 6’s, so you’ll see them on both lists below.)
- Seafood (sources both high in omega-3’s and low in environmental
contaminants include anchovies, herring, mackerel, oysters, wild salmon, and sardines)
- Hempseed oil
- Canola oil
- Pumpkin seeds
- Marine microalgae (Most algae-based supplements contain docosahexaenoic acid [DHA],
but no eicosapentaenoic acid [EPA] — see our article on
vegan sources for more info.)
- Borage oil
- Evening primrose oil (EPO)
- Sunflower oil
- Safflower oil
- Corn oil
- Canola oil
You may wonder why olive oil isn’t on either of these lists. The reason is
because its two main fatty acids are oleic acid, an omega-9, and palmitic
acid, one of the most common saturated fatty acids found in both
plants and animals. In other words, olive oil contains no omega-3’s (or 6’s).
But of course, it’s superb for your health nonetheless, due to its
bioflavonoid content. (See our pages on omega-3’s and the
Mediterranean diet and the
differences between 3’s, 6’s and 9’s for more specifics.)
Omega-3’s and omega-6’s — a healthy balance is best
These days, all omega-3’s tend to be being lumped together as “good
fats” and all omega-6’s as “bad fats.” This good–bad thinking
is probably because we are getting so many 6’s and too few 3’s. And,
in broad terms, omega-6’s do favor inflammation, while omega-3’s counter
it. And this increase in inflammation is what contributes to the very diseases omega-3’s
have been proven to help. But the reality is that both 3’s and 6’s are
essential to our bodies.
That said, it’s not so much that we need lots of both, though: it’s
the ratio of 6’s to 3’s that we get that is most relevant to
our health and longevity. Concerning that ratio, let’s take another look at
the foods listed above. Researchers agree that the optimal ratio of omega-6 to omega-3
is somewhere between 2:1 and 4:1. Yet the typical American diet provides a ratio
of anywhere between 10:1 and 30:1!
This imbalance, tipped disproportionately in favor of omega-6 over omega-3, stems
in part from a diet laden with animal fats, such as corn-fed beef, and other corn-derived
products, and lacking in seafood, seeds, and nuts. But it may also stem from overreliance
on packaged, fast and fried foods high in hydrogenated oils, or trans fats.
We don’t yet fully understand how trans fats upset the scales, but we do know
that they’re metabolized very differently from other fats, and interfere with
the conversion of all other dietary fats.
While we’re on the subject of good and bad, I would like to explain that the
only truly “bad” fats are the ones not found in nature: trans fats.
The food industry creates hydrogenated trans fats by pumping extra hydrogen atoms
into their molecular configuration, to create a malleable, melt-in-the-mouth, yet
solid-at-room-temperature product. Along with prolonging the shelf-life of all sorts
of processed foods — cookies, crackers, breads, spreads, sauces, fried foods
and snack foods — trans fats have been shown to raise LDL (“bad”)
cholesterol and increase the risk of heart disease.
If the words “hydrogenated” or “partially hydrogenated”
are listed in the product’s ingredients, do yourself a favor and just don’t
buy it. And because federal regulations permit a product’s label to claim
“Zero trans fats” if its trans fat content is less than half a gram
per serving, be sure to check that the serving size listed hasn’t been minimized
to ridiculously small proportions. (For more on trans fats, read the
truth about cholesterol and fat.)
Omega-3’s and disease prevention
The more we learn about omega-3’s, the more amazing they seem: how can something
so simple, so affordable, and so readily available be so good for us? Because of
their anti-inflammatory properties, omega-3’s have been linked with prevention
and treatment of a whole host of health problems, including:
- Heart disease
- High cholesterol
- High blood pressure
- Depression/bipolar disorders
- Skin disorders
- Breast, colon, and prostate cancers
This list goes on and on. So it’s no surprise that omega-3 fatty acids are
quickly becoming one of the most researched topics in the scientific community —
and one of the most celebrated among people who care about whole health. Yet data
indicate that, for most people, omega-3 fatty acid intake continues to decline!
Omega-3’s and women
In my opinion, supplementing with omega-3 fatty acids is a no-brainer, especially
for women. We’ve been using omega-3’s at the clinic for years with great
success. From menstrual cramps to menopausal symptoms and breast cancer, omega-3’s
can help women of all ages.
Let’s start with women in their reproductive years. Scientists have found
a correlation between increased menstrual pain and low omega-3 concentrations in
the blood. Dysmenorrhea,
or menstrual cramps, occur when cell membranes release omega-6 fatty acids, which
then produce proinflammatory eicosanoids. Cramps, nausea, headache and other menstrual
symptoms are the result.
Infertility and premature
birth are two other women’s health issues where omega-3 research is coming
up strong. One study showed increased fertility rates with omega-3 supplementation.
Researchers observed that omega-3 supplementation reduced clotting in the endometrial
cells lining the uterus, which improved the implantation rates of fertilized eggs.
Additionally, an imbalanced omega-6-to-omega-3 ratio has been linked to
polycystic ovarian syndrome (PCOS), another cause of infertility in some
When pregnant women increase their omega-3 intake, the risk of premature birth plummets
by up to 50%. Fetal brain development also benefits from omega-3 supplementation,
especially DHA, during gestation as well as after birth. Moms who supplement for
the sake of their infants also lower their risk of postpartum depression.
For women with a history of cancer, we now have research on the effect of different
types and amounts of fats on tumor growth. Fatty acids can be both protective or
harmful depending on the situation, but an excess of the proinflammatory eicosanoids
derived from omega-6’s can have a negative effect on the immune system, and
may account for accelerated growth of certain cancers.
Since the metabolites of omega-3’s are known to counterbalance those of omega-6’s,
scientists are looking for ways to use omega-3’s to block the growth of tumors.
Animal studies have already demonstrated that a high-omega-3 diet can slow tumor
growth, and people following a Mediterranean diet (rich in omega-3’s and other
phytonutrients) have been found to be 56% less likely to develop cancer and 61%
less likely to die from it.
Omega-3 fatty acids and menopause
If you’re not convinced about incorporating quality omega-3’s into your
diet yet, there’s more. Omega-3 fatty acids can help many of the issues we
experience in menopause. As I mentioned before, low blood levels of omega-3’s
are associated with inflammation, which is the fire beneath so many health problems
arising in menopause — osteoporosis, heart disease, vaginal dryness, thinning
skin and hair, joint pain and dry eyes, to name some familiar ones. And o-3’s
can calm this inflammation. Let’s take a look at the specifics. Omega-3’s
can help with the following:
Hot flashes. In reporting the results of two small, but
well-controlled studies, a team of Italian scientists in 2005 attributed a “progressive
and highly significant reduction” in
hot flashes to omega-3’s, possibly through their influence on nerve
cell membranes or by modulating neurotransmitter function. In fact, a diet high
in omega-3’s may be one of the reasons why Japanese women, whose diets are
rich in fish, seaweed and soy, have fewer menopausal problems than American women
Osteoporosis. Normal bone is constantly being broken down
(resorbed) and rebuilt. When resorption exceeds formation, bone mass slowly deteriorates,
which can lead to the condition we know as osteoporosis. Derivatives of omega-6
fatty acids are stimulators of bone resorption. Fortunately, it’s never too
late to start rebuilding good bones, and we can call on omega-3’s to counteract
omega-6’s and help prevent and treat osteoporosis.
Mood, affect and memory. These are all challenges as we
grow older. Some research on omega-3’s shows promise for preventing, and possibly
treating, depression. Omega-3’s
may likewise be helpful for people struggling with personality and behavioral problems
such as aggression. Researchers recently found that people with high levels of omega-3’s
in their blood had more grey matter in the sectors of the brain associated with
positive emotions and moods, while the subjects with mild to moderate depression
symptoms showed decreased grey matter in those same areas. More research is needed
to determine whether omega-3’s actually cause this phenomenon, but
it’s safe to say that healthy omega-3 levels can mean a more positive outlook
on life and lower rates of memory loss.
Cardiovascular disease. We know that women, especially
those over 40, whose lipid profiles show a high ratio of triglycerides to HDL (“good”
cholesterol) are at increased risk for
cardiovascular disease. Omega-3-rich fish oil supplements do double-duty
in protecting the heart and blood vessels by bringing triglyceride levels down while
at the same time increasing HDL. Taking omega-3’s is also a good idea if you’re
on conventional hormone replacement therapy,
because HRT can increase triglyceride levels to unhealthy levels.
Lower heart rate = longer life? Perhaps longevity is the
ultimate omega-3 benefit to reap. Researcher Jørn Dyerberg, known throughout
the world for his pioneering work on omega-3’s, was the first to note the
virtual absence of heart disease among Greenland’s indigenous people. Attributing
this directly to their high dietary omega-3 content, Dyerberg believes that the
net effect of lowering the number of heart beats over a lifetime is a heart that
beats longer — in other words, a longer lifespan. More research is called
for, but studies suggest that DHA is the principal omega-3 fatty acid responsible
for lowering heart rate and improving resilience of heart rate variability, which
together lower risk of deadly sudden cardiac events significantly.
All told, that’s a pretty essential nutrient, wouldn’t you say? Now
that we understand why omega-3’s are so essential, the next questions
to explore are What kind of omega-3 is best? and How much omega-3’s
should you take?
Getting it right — how to pick your omega-3 supplement
Naturally, getting omega-3 fatty acids fresh from the source in our diets is ideal,
but let’s be honest: our busy lives don’t always allow for this. There
are loads of companies out there selling omega-3 supplements, and I always tell
my patients to base their choices on the quality and purity of the product.
Omega-3 fish oils should be sourced from deep-water fish inhabiting the least polluted
waters on earth. Unfortunately, oily fish can contain high levels of toxic pesticides,
dioxins, PCB’s, or heavy metals such as lead and mercury, all of which must
be removed in the preparation process for omega-3 supplements. Today, highly advanced
omega-3 extraction and distillation processes efficiently remove toxins and impurities
as well as maintain stability and freshness. If you are concerned about purity,
call the manufacturer and request a certificate of analysis, where they show the
results of tests for levels of lead, mercury, and cadmium in each batch.
Another consideration is dosage. The American Heart Association recommends consuming
1–3 grams per day of EPA and DHA. For certain medical conditions, however, higher
doses of omega-3 products, up to 4 grams per day, can be used safely, and with good
effect. A number of recent studies show that higher-dose omega-3 fatty acids can
be extremely helpful, for example, for lowering high triglycerides, and that they
are usually very well tolerated. We encourage you to talk with a qualified healthcare
practitioner before using higher than average doses of omega-3’s (more than
3 grams [>3000 mg] per day).
At Women to Women, we know that the basis of health is balance, not overabundance.
Unless your healthcare provider recommends otherwise, your best bet when purchasing
omega-3 supplements is to base your choice on the following criteria:
- Look for natural forms that have been purified by molecular distillation,
to ensure the product is free of mercury and other contaminants.
- Look for added antioxidants.
- The label shouldn’t suggest more than 3 grams of EPA and DHA per day
- Look for both EPA and DHA in the supplement. Since they can be
interconverted, the ratio of EPA:DHA is not as important as quality and amount are,
but both should be present, and a reasonable ratio to look for is 3:2.
- Always check the expiration date, and take note of any
bad smell or taste, which may mean the product was poorly purified, has expired,
or has already oxidized. (Note that a fishy smell does not necessarily mean the
fish oil is bad, just that it has not undergone a process to remove that odor.)
In addition to taking a high-quality omega-3 supplement, one of the best ways to
optimize your omega-3 intake is by following a
Mediterranean diet. Generous amounts of richly colored fruits and vegetables,
virgin olive oil and fresh fish can help your body acquire a healthier balance.
Getting back to omega-3 balance — the Women to Women approach
There’s no question that increasing your omega-3 fatty acid intake promotes
better health, especially for women. From PMS to menopause and disorders like Alzheimer’s,
heart disease and osteoporosis, they can help women of all ages reduce harmful inflammation
and restore the balance we’ve moved away from with our modern, omega-6-heavy
There are many ways to get your omega-6-to-3 ratio back where it’s meant to
be. As you begin the process, here are some tips we’ve found helpful in restoring
- Consider testing your omega-6/omega-3 ratio. If you have symptoms
of inflammation or some of the other health risks we’ve discussed above, ask
your healthcare provider for a fatty acid profile test. It’s not always easy
to remember, let alone share the exact details of our diets with our healthcare
providers. Testing gives you both you and your provider an objective number to use
as your individual starting point.
- Transition to a more
Mediterranean style of eating. Carve out some time to plan your weekly
menu — you may not even have to spend a lot of time, once you get the hang
of it. Look for simple recipes made from fresh whole foods that you can chop up
and prepare ahead of time. That way, it will be simpler to serve a wholesome meal
when you come home after a long day, and you’ll have time to relax and savor
it fully. Stock up every week on a sampling of brightly colored fresh fruits, vegetables,
and nuts for quick and easy snacks. Keep your nuts and oils refrigerated.
- Supplement with high-quality omega-3’s daily. For women who
eat at least two seafood servings a week and who have no pressing health concerns,
600–650 mg of EPA and DHA per day may be sufficient. Those with health concerns
shown to benefit from omega-3’s may want a higher intake, of 1000–3000 mg
per day. Up to 4000 mg per day may be used only under a physician’s care.
If you supplement with fish oil, always choose natural, stable preparations of the
highest quality and purity (like the
we offer through our Personal Program).
- Include a high-quality multivitamin-mineral complex supplement.
Pyroxidine, biotin, calcium, copper, magnesium and zinc are all nutrients that help
convert the parent omega-3 ALA into EPA and DHA. Getting enough of these nutrients,
by planning and preparing perfectly nutritious meals every single day, week after
week, is just impossible for most of us. As much as we’d all like to eat this
way, you can be certain to replenish your body’s supply of these important
micronutrients by taking a high-quality nutritional supplement (like the one we
offer in our Personal Program).
A lesson from the past — balance
Thousands of years ago, before the advent of agriculture, the human diet was much
closer to the earth and sea than it is nowadays, and provided omega-3 fatty acids
in far greater quantities than our modern diets do. For millennia people ate whatever
they could hunt, catch, dig or pick without thinking much about nutrition or what
was “good” or “bad” for them. They simply wanted to be full
and nourished. Their greater challenge was simply to find enough. With the abundance
of food choices today, though we still have to “hunt” for what is best,
omega-3-rich foods and supplements are readily available.
With all the promising science being released about omega-3’s, it’s
refreshing to know that this fat is all it’s cracked up to be. But
like everything else, a fish oil pill isn’t a magic bullet. It’s all
about balance — on a cellular level with your o-3/o-6 ratio as well as on
the level of your life as a whole. No supplement or pill is going to erase all your
health problems. But I promise that incorporating good nutrition with a positive
outlook will help keep you on the path to the long and disease-free life you deserve.
