The
cholesterol / lipid panel is a test that has become an integral part of
the American health care system. Many of us have heard the diagnosis
from our Primary Care docs - "your cholesterol level is too high"; however, what is considered "too high" is an
arbitrary number at best and changed numerous times to reflect current
trends. After that
comes the standard advice- cut back on your fat intake, lose weight,
exercise, and maybe even take the latest and greatest statin drug-
because we all know that cholesterol is a bad substance that causes
heart disease. Or does it?
Many
have tried to follow this advice, but at what cost. The statin drugs
are not without side effects- muscle pain, weakness and tingling,
fatigue, memory loss, increased cancer risk, depression and sexual
dysfunction. And
don't even get me started on low fat diets. Low fat = high carb =
weight gain= metabolic syndrome = type 2 diabetes. Well, that went well.
Healthy fat IS NOT a problem with cholesterol levels and IT NEVER WAS.
Trans fats are a different story.
Exercise is important, but not many people really follow this advice, though I whole-heartedly indorse regular exercise.
What
if I told you Cholesterol is a very important body substance, and there
is a lot of new theory to back this up. "The Great Cholesterol
Myth" - by Dr. Stephen Sinatra MD, cardiologist and Dr. Johnny Bowden
PHD Nutrition, provides plenty of evidence.
So what do the numbers on the cholesterol/lipid panel actually reflect? Let's review. A typical lipid panel will show Cholesterol, Triglyceride, HDL, LDL, and VLDL levels.
Cholesterol
is a waxy substance, an important part of ALL of our 50 trillion cell
membranes. Most of it is made in our liver, a little is absorbed from
the diet. Cholesterol is the basic building substance for all of our
Estrogen, Progesterone, Testosterone, DHEA, and Adrenal hormones. It
is a major component of bile - responsible for fat digestion and the
extraction of Vitamins A, D, E and K from our dietary fats. It is a
super antioxidant and super protector for all of our cells. Current
recommendations are to keep your number under 200; but if your number is
under 150 you are at increased risk for cancer. If your number is higher than 200
it could be a marker of infection or inflammation in the body. In some people
there is a genetic component to this number.
Cholesterol
travels to all parts of the body in the form of lipoproteins- namely
HDL (high density lipoprotein) and LDL (low density lipoprotein).
HDL
is considered the good cholesterol. A HDL of 60 or higher is considered
optimal for health. But some new evidence states that there are
subgroups of HDL and what subgroup you are in is also important. This is
not commonly tested. Also HDL is more controlled by genetics then LDL.
LDL
is considered the "bad cholesterol" (though why we think nature would put
a bad substance in our body is beyond me). The lab normal for LDL is a
result under 100. But again it is not that simple. There are also
subgroups of LDL. This is the most important information for you if
your LDL is elevated. There is a test called "Lipoprotein particle size or
VAP ". Large fluffy, buoyant LDL-A is the preferred result. Small,
hard, dense BB size LDL -B molecules are a different story. There is
also some genetic predisposition for some with high LDL levels.
TRIGLYCERIDES
are another type of fat in the body. These are the storage form for
excessive carbohydrates (note I did not say fats). If triglycerides
are high, it is a tip off that you need to radically reduce the amount
of simple sugars and alcohol in your diet. Eating low carb is also one
of the ways to change those small BB size LDL particles to the large
buoyant ones, along with exercise. Intermittent fasting is also helpful.
VLDL
(very low density lipoprotein) is the carrier form of triglyceride. So
if both VLDL and triglyceride are elevated, it's time to rethink your
diet.
Chronic
stress and lack of sleep, which is viewed by the body as stress, will
also affect these numbers because of the cortisol connection.
So
to quote Dr. Sinatra, "Inflammation, NOT CHOLESTEROL, is at the "the
heart" of heart disease. It's worth pointing out that the metabolic
effects of sugar and all processed foods are highly inflammatory to your
artery walls."
So relax and enjoy healthy fats!
