The myths, lies, and misconceptions about saturated fat and your health.

I've written many times in the last
couple years about the mistaken beliefs in society about saturated fat
and the false perception in the media AND with MOST health professionals
that saturated fat is bad for you.
If you've seen in some of my
articles, I've even showed you why saturated fat can even be GOOD for
you in some cases, despite every health/fitness professional in the
world just accepting the false belief that it's bad for you.
Note
- I'm NOT saying that an "Atkins style" diet is good for you! Atkins
style diets are generally NOT a healthy or balanced way to eat! Atkins
style diets typically promote processed meats full of additives, excess
salt, and imbalanced omega-6 to omega-3 ratios (since most grocery store
meats are grain fed and not raised in a healthy manner). Also, Atkins
plans typically have a lack of many other important food groups,
nutrients, and antioxidants.
Rather, what you'll see in this
article, is that saturated fat is a perfectly natural part of the human
diet and has been for eternity... it is NOT the evil demon it has been
made out to be!
I have to say I was pleasantly
surprised to FINALLY see a big name publisher have some guts to publish
an article about why everyone in the world may be wrong about their
beliefs about saturated fat.
I picked up a new issue of Men's
Health magazine recently, and they have a huge 6-page article in there
about the faulty research in the past about saturated fat, and some new
emerging research that is showing why it may actually be more good for
you than you would believe.
I've got to give them credit...
the article was VERY well researched and put together beautifully to
summarize where the studies in the past have gone wrong, and why recent
studies are showing that everyone may have been wrong for the last 5
decades about saturated fat.
I'd highly suggest you read the
entire article if you can. If not, I'm going to try to give you a quick
summary of the findings here since it was a long article...
The "Fact" that saturated fat is bad for your health has never been proven by legitimate studies
First of all, did you realize that
although doctors, nutritionists, fitness professionals, and the media
all have told you that it's a FACT that saturated fats are bad for you,
this "FACT" has actually never been proven!
It's actually not a "fact" at all. It was a hypothesis!
This goes all the way back to a flawed research study from the 1950's
where a guy named Ancel Keys published a paper that laid the blame on
dietary fat intake for the increasing heart disease phenomenon.
However, there were major flaws to
his study. For one, in his conclusions he only used data from a small
portion of the countries where data was available on fat consumption vs
heart disease death rate. When researches have gone back in and looked
at the data from all of the countries, there actually was no link
between fat consumption and heart disease deaths. So his conclusions
were actually false.
Second, his blaming of fat intake
for heart disease was only one factor that was considered. There was no
consideration of other factors such as smoking rates, stress factors,
sugar intake, exercise frequency, or other lifestyle factors.
Basically, his conclusions which
blamed heart disease deaths on fat intake were really just a shot in the
dark about what a possible cause may have been, even though all of
those other factors I just mentioned, plus many others, may be the
bigger cause.
Unfortunately, Keys study has been
cited for over 5 decades now as "fact" that saturated fat is bad for
you. As you can see, there certainly is nothing factual about it.
Since that time, numerous other
studies have been conducted trying to link saturated fat intake to heart
disease. The majority of these studies have failed to correlate ANY risk at all from saturated fat.
A couple of them made feeble attempts at linking saturated fat to heart
disease, however, it was later shown that in those studies, the data
was flawed as well.
Another issue with flawed studies is that many studies have lumped
artificial trans fat intake together with saturated fat intake, and
mistakenly laid the blame on saturated fat despite the overwhelming
evidence that artificial trans fat is the REAL health risk. This is a
HUGE mistake as there is a vast difference in how your body processes
nasty artificially created trans fats vs the perfectly natural saturated
fats that have been part of the human diet since the beginning of man.
Do we actually have evidence that saturated fat may actually be good for you instead?
Well, let's consider a few examples...
Did
you know that there are several well known tribes in Africa... the
Masai, Samburu, and Fulani tribes... where their diet consists mostly of
raw (unpasteurized) whole milk, lots of red meat, and cows blood? The
typical members of these tribes eat 5x the average amount of saturated fat compared to overweight, disease-ridden Americans.
Despite their very high saturated
fat intake, they display extremely low body fat levels, and heart
disease and diabetes to natives of the tribe is virtually non-existant.
Now most critics of this example
will say that it must be related to superior genetics... however this is
false, as when they studied tribesman who had moved out of their native
lands and started eating more modern day diets, their blood chemistry
skyrocketed with heart disease risk factors.
This
is true of certain pacific island countries inhabitants as well.
Several studies have shown that certain pacific island nations had VERY
high intakes of total fat as well as saturated fat from tropical fats
such as palm, coconut, and cocoa. Tropical plants in general have
naturally higher levels of saturated fats in their tissues due to the
warmer climate.
Despite super-high intakes of
saturated fat, these island natives were typically very lean and heart
disease was virtually non-existant. However,
when researchers followed up with islanders that had moved away from
their native island and adopted a typical western diet, the heart
disease risk factors were through the roof. Hmm, once again, another
example of people that started eating LESS saturated fat and more
processed western foods and INCREASED their heart disease factors.
In fact, did you know that although
saturated fat intake does increase your LDL bad cholesterol, it
actually increases your HDL good cholesterol even further, hence
improving your overall cholesterol ratio, which has been proven to be
more important that just total cholesterol level
(actually total cholesterol is an almost useless number... inflammation
is the REAL problem, but that's a whole different topic).
Another fact worth noting in favor of saturated fat...
Saturated fat is comprised of
various different types... the 3 most common types are stearic acid,
palmitic acid, and lauric acid.
Stearic acid is found in animal fat
and cocoa in higher levels. Research continues to show that stearic
acid has no negative impacts on heart disease risks. If anything, it's
either neutral or beneficial. In fact, your liver breaks down stearic
acid into a monounsaturated fat called oleic acid, which is the same
type of fat that makes up most of heart-healthy olive oil. Bet you didn't know that!
Lauric acid is beneficial as well. Not only has it been shown to increase your HDL good cholesterol
levels significantly, but it is also lacking in most Americans diet and
has even been shown to have some powerful immune-boosting effects
potentially. It is even being studied currently in HIV/AIDS research to
help improve immune function in patients.
Tropical oils such as coconut and palm are the best sources of the healthy saturated fat - lauric acid.
Palmitic acid is the other main component of saturated fat and has also been shown to increase HDL good cholesterol
to the same, if not greater extent than LDL bad cholesterol, thereby
making it either neutral or beneficial, but certainly not bad for you.
So, if all of these researchers
have tried so hard over the years to point the finger at saturated fat,
but have continued to fail to show a correlation between saturated fat
and heart disease risk, what are the REAL culprits for heart disease?
Well, here are the REAL causes of heart disease risk:
- Trans fats (artificially hydrogenated oils)... see my other Trans Fats article here on my blog
- Heavily refined vegetable oils such as soy, cottonseed, corn oil, etc. (inflammatory inside the body, and typically throw the omega-6/omega-3 balance out of whack...remember, inflammation is the REAL cause of heart disease, NOT dietary saturated fat or cholesterol). Read more about healthy cooking oils vs unhealthy cooking oil on this blog..
- Too much refined sugar in the diet (including high fructose corn syrup)
- Too much refined carbohydrates such as white bread, low fiber cereals, etc
- Smoking
- Stressful lifestyle
- Lack of exercise
- Other lifestyle factors
hmm... do multi-billion dollar industries really have an influence on the way data is portrayed to the public? Of course they do! And don't even get me started on the cholesterol meds industry! Again, I digress.
I hope this article has opened your eyes about the truth about saturated fat and how you've been misled over the years.
One other fact in favor of saturated fat... Researchers have discovered recently that a unique vitamin called vitamin K2 is strongly associated with protecting your body from heart disease. However, vitamin K2 is not found in many foods, and can you guess what one of the best sources is? That's right, the fat from grass-fed dairy! So that means one of the foods that "health experts" have been telling you to avoid for all these years, dairy fat, is actually one of the best sources of heart-protecting vitamin K2.
The true FACT is that saturated fat is a neutral substance in your body, and even beneficial at times as we've seen in this article, and not a deadly risk factor for disease. The REAL risk factors are what I listed above.
