If common knowledge
has ever gotten anything wrong, it is on the subject of fat; specifically
the saturated kind, which has been
demonized for years. We have been "taught" for so long that the
low fat options offered to us are the healthy choices. This message is
presented so strongly that they even make 'fat-free' fat. (Refer to the peanut
butter shelves and margarine selections at the store).
The standard American
diet gravitates us right to low-fat, high-carb choices. The United States
Department of Agriculture (USDA) has had years of government endorsed food
pyramids, and now, the new My Plate, suggesting what and how we should eat.
Fortunately, these
are just suggestions, and often not well researched suggestions. It just seems
to me that USDA and the American Dairy Association have a pretty vested
interest in marketing the benefits of grains and dairy, so their opinions on
what we should and should not eat should be taken with a grain of salt.
What nobody mentions
is that the high carbohydrate, sugar filled alternatives placed in front of us
are not the optimal source of fuel the human body. Something else that
seems to get overlooked, are the cheap chemical fillers used to put flavor back
into these food-like substances.
In hindsight, I am not sure what my initial hangup was. I was
basically getting permission to add extra butter to everything and eat bacon
whenever I wanted...and I was hesitating?!?! I have yet to meet a person who
can complain about more butter or bacon.
I have digressed. Let
me reiterate; low-fat does NOT equal health food. Low-fat usually equals things
like chemical alterations, fake flavor, pseudo sugars and the ever-evil high
fructose corn syrup.
I want to address
what you may be thinking...perhaps something like "eating fat will make me
fat" or that "saturated fat will clog my arteries." While this
may seem logical, the reality is that fats only turn to fat in the body in
the presence of too much carbohydrate. Fat also isn't water soluble. A
quick Google search tells us that our blood is over 80% water, so the
suggestion that saturated fat can enter and clog arteries begins to make less
sense. Let's take a quick look at some details:
Saturation: one method used to classify fatty acids. We will just talk about saturated fatty acids, and trans fats today.
•
Saturated fat is made solely of saturated fatty acids (SFAs),
meaning that all of its bonds are filled. There are no open holes, it is fully
saturated, which means nothing foreign can get in and cause it to spoil. This
makes the fat resistant to high heat, gives it a long shelf life, is solid at
room temperature, and is compatible with and essential to many functions in the
human body. Half of human cell membrane structure is made of saturated fat, and
it is used by the body as a source of energy. (Sisson, 2009). Your body
actually converts and stores excess carbohydrates as saturated fat for later
use; humans are fat burners by default.
•
Trans fat rules the bad fats. Trans fats are unsaturated fats that
have been through a hydrogenation process; meaning the oils have had hydrogen
atoms added to them to make them thicker at room temperature. (think margarine
and shortening) A seemingly simple process that may have began with good
intentions, but unfortunately, this man-made operation unleashes havoc in our
bodies.
We could spend paragraphs picking apart good and bad fat sources,
so in an effort to not bore you, check out this link for a good guide to fats. In the meantime, do yourself a
favor and get rid of all the vegetable and seed oils in your cupboard, and if
you see anything that contains the word "hydrogenated" on
the label, run as far away as possible.
A lot of conventional
wisdom and basic assumptions will tell us that glucose (which comes from
carbohydrates) is the preferred source of energy for the body; but the body can
only hold so much glucose for energy, before it begins to store it as body fat.
The liver (and other glucose burning organs) can only hold about a days worth
of glycogen for energy use. The muscles can store enough to fuel about 90
minutes of reasonably intense physical activity (Sisson, 2011).
I feel it may be important to state at this point, that I am not
afraid of carbohydrates. After all, vegetables are carbohydrates. The
major problem with conventional carb intake is that the cheapest and most
available sources of carbohydrates are from processed grains and sugar.
Educating yourself and making smart choices really does make all the
difference. To conclude, I would like to share a brief list of some
of my favorite fat/energy sources:
•
Avocado - An excellent monounsaturated fat source, these are one of my
go-to favorites. Avocados are a very healthy fat source, loaded with vitamins,
mineral, and antioxidants. I also find them a very filling compliment to bacon,
eggs, salads and burgers.
•
Coconut and Coconut Oil: This fairly unique fat source is a medium chain triglyceride,
which essentially means that it is easily absorbed and put directly to use,
energizing our bodies. This easily digested oil is my favorite to cook with,
the milk is excellent in soups and dips, and shredded coconut meat makes a
great snack.
•
Animal meat: Comes in many forms, flavors, and with tons of other
nutrients to boot. Humans need it, and thrive on it. Go grass-fed on your beef, pasture-raised on your chicken and eggs, and wild
caught on your fish, whenever possible. This will help to avoid harmful
antibiotics and hormones.
•
Ghee: Clarified butter adds an excellent flavor to sautéed vegetables or
fried eggs.
•
Olive Oil: Excellent to drizzle on salads or on top of a bowl of
soup. Olive oil does turn rancid easily if heated, so this is best used added
to cold or cooked food.
