Popular
wisdom in the media is that we, the public, should be working
to reduce the amount of fat in our collective diet. Working strictly
from the perspective of calories, fats have a higher caloric density
than either carbohydrates or protein, and the typical Western
diet is laden with saturated and trans fats, both of which are
known to increase cholesterol, triglycerides, and generalized
inflammation within the body. So, while a blanket recommendation
to reduce fat consumption looks good on the surface, digging deeper
into the science of weight loss and muscle growth shows the folly
of such an approach.
As
was recently highlighted, the consumption of omega-3
fats is imperative for good health and immune function. Both omega-3
and omega-6 fats are necessary for biochemical processes within
the body, including the regulation of generalized inflammation,
insulin response, and protein synthesis. Unlike omega-9 fats,
humans are incapable of synthesizing these two essential fats
internally, so they must be acquired by consumption. While the
typical Western diet is rich in omega-6 fats, most Americans obtain
little dietary omega-3 fats.
While
serious body builders are less likely to suffer the negative consequences
of a high fat diet, their heavy focus on fueling muscle growth,
while simultaneously reducing body fat, naturally leads to a high
protein, low fat diet. This makes them susceptible to the long-term
downsides of low omega-3 consumption. Many body builders mitigate
this downside risk by choosing supplements that contain omega-3
fats. This approach works admirably, but another method to achieve
this goal is through the consumption of foods that are both high
in protein and omega-3 fats. Research shows that omega-3 fats
are more readily absorbed from foods than supplements, and practitioners
get the additional benefit of the micronutrients found in these
foods, which are also more readily absorbed from foods.
Its
common knowledge that salmon and flax seed are excellent sources
of omega-3 fats, but choosing a daily dose of salmon is both boring
and unsustainable over the long term, and flax seed oil suffers
from storage stability problems. Fortunately, there are viable,
alternative, food based sources of omega-3s. Here are three:
Sardines
Sardines, and their cousin the herring, are among the richest
sources of seafood based omega-3 fats available. In recent times,
these hearty fish have fallen out of favor, as diners tastes have
moved toward milder fishes. Sardines have been a staple of the
human diet for thousands of years, and when compared against salmon,
sardines have a similar amounts of protein and fat, while also
being a rich source of phosphorus, vitamin D, vitamin B-12, and
selenium. Sardines and other small fish offer the added benefit
of improved sustainability by virtue of their shorter time to
maturity.
Canola
Canola oil, which is a plant-based cooking oil, is an alternative
to flax seed for the omega-3 fat known as ALA. A derivative of
the rapeseed plant, which in addition to omega-3 fats also contains
two toxic chemicals, the production of toxic compounds was bred
out by Canadian growers, resulting in the canola plant. Although
the ratio of omega-3 to omega-6 fats in canola isnt as good
as in flax seed oil, canola oil also doesnt suffer from
the disadvantages of rapid spoilage, or the high cost, of flax
seed oil. Although it isnt really suitable for frying or
baking, it is a viable alternative to corn and soybean oils for
generalized cooking and low temperature applications, such as
dressings and dipping oils.
Cod
Almost everyone has heard of cod liver oil, and likely has a grandparent
who made that part of their daily routine as a ward against generalized
ailments. Made famous by the collapse of the cod fishery off the
U.S. northeast seaboard, cod fish offers the advantage of being
lower in fat than salmon, while providing an equivalent amount
of protein. This translates into fewer calories per serving. As
a bonus, of the omega-3 fat present in cod, the majority is DHA,
which is the essential fat responsible for improved brain function.
Tack on the recent advances in establishing sustainable cod fisheries
in both Pacific and Atlantic fisheries, and cod becomes a viable
alternative to salmon for both omega-3 and protein.
Despite
its reputation, fat is an essential component of a healthy diet.
Just like so many things in life though, moderate consumption
of a wide variety of healthful fatty foods yields the greatest
benefits. So the next time youre looking for a good source
of omega-3s, try out these three sources.
