May Ward Off Cancer,
Heart Disease
If you’ve
read many of the recent reports about the benefits of
flaxseed, you may easily wonder how one simple seed
can reduce cholesterol and triglycerides, ward off
arthritis, aid in diabetes treatment, treat psoriasis,
improve menopause symptoms, fight heart disease, and
even shrink cancerous tumors.
An
increasing number of health experts are suggesting
that it may be the lack of foods like flaxseed in our
diet that is responsible for some of these diseases to
begin with. Here in the West we tend to eat foods with
a predominance of omega-6 fatty acids (found in
vegetable oils and grain-fed livestock) over the
omega-3s (found in fish and flaxseed). We eat fairly
large quantities of grain-fed meats, which are high in
omega-6s. And our vegetable oils of choice are high in
omega 6 too. (The ratio of omega-6s to omega-3s in
corn oil is 28:1.)
In
contrast, populations with high intakes of omega-3
fatty acids have low risks of cardiovascular disease.
And studies of Paleolithic nutrition have indicated
that humans evolved on a diet higher in omega-3s.
Flaxseed has the highest level of plant omega-3s.
But
Omega-3s are just part of the story. Flaxseed also
contains high levels of phytohormones (plant hormones)
called lignans. Scientists are just beginning to study
these powerful compounds that our bodies use to
regulate our own hormones.
While
lignans are available in small amounts in many plants
(including barley, oats and millet), flaxseed is the
richest available source – with 100 times more
lignans than any other plant food. It’s important to
note, however, that lignans are not present in high
quantities in flaxseed oil, even so-called "high-lignan"
oils. In order to get the benefit of lignans, choose
whole, ground flaxseed.
Whether
it is the omega-3 fatty acids, the lignans, or some
combination of the two, flaxseed has demonstrated
anti-cancer properties in both animals and humans. One
study showed that rats fed a diet supplemented with
flaxseed produced fewer and smaller tumors when
exposed to cancer-inducing agents. In a study
completed in December 2000, flaxseed-enriched muffins
were as effective as preoperative tamoxifen at
reducing breast cancer cell proliferation.
An
earlier study demonstrated that alpha-linolenic acid
(ALA), a fatty acid found in flaxseed, can protect
against fatal heart attacks. These omega-3s also help
the body metabolize glucose, which makes flaxseed an
excellent aid for type-2 diabetics. Due to its
anti-inflammatory properties, flaxseed has also been
demonstrated to be effective against arthritis, Crohn’s
disease, colitis and psoriasis.
How
much do you need?
There
is no RDA yet for omega-3 fatty acids or lignans, but
the World Health Organization and others have made
recommendations. Try starting with about 1 tablespoon
of whole ground flaxseed per day, and work your way up
to somewhere between two tablespoons and ¼ cup. Make
sure to get extra fluids to help your body handle the
extra fiber.
How
does flaxseed taste?
It
really depends on which variety you use and how you
use it. One of the most enjoyable ways to use flaxseed
is in baking. In most baked goods, ground golden
flaxseed is more subtle – both visually and in
flavor – than whole wheat fiber.
Where
to buy it
It may
be harder to find golden flaxseed, but an increasing
number of health food stores are stocking it. You can
also buy it directly from one of largest growers of
flaxseed in the U.S., Heintzman Farms. For more

or call 1-888-333-5813.
Selecting
the seed
Choose
seed Most people prefer golden flaxseed. It has a
milder flavor than the brown seed, integrates more
easily into recipes, and is often of higher quality.
(Most brown flaxseed is grown for industrial purposes.
In contrast, golden seeds are usually grown for human
consumption.)
RECIPE
Toasted
Flaxseed*
¼ cup
whole (un-ground) golden flaxseed
1 tbsp butter
2 microwave-proof single-serving bowls
Place 1
pat of butter in the center of a single-serving
microwave-proof bowl. Add ¼ cup whole golden
flaxseed in the bowl. Place a plate or another bowl on
top as a lid. Microwave for 3 to 4.5 minutes,
depending on oven power. Remove and stir after one
minute, and again after each additional 30 seconds.
Flaxseed should be browned, crunchy and easier to bite
through hull. Toasted flaxseed is delicious on baked
potatoes, fish, green beans, cottage cheese, salads. Note:
Recipe does not work with brown flaxseed.
