B Vitamins for Cholesterol
Q.
I have a high cholesterol 299 mg/dl. My sister
sells vitamins and tells me I should take
B
vitamins to help with my cholesterol. I have
been watching what I eat but the cholesterol
does not go lower than 235 mg/dl. Is there
any reason why I should take a vitamin supplement
for my cholesterol?
A.
Your sister may have some truth to what she
is telling you. In the past 10 years scientists
have found high levels of homocystiene to be
a risk factor for coronary artery disease and
other vascular diseases. Scientists have
concluded that homocystiene is up to 40 times
more predictive than cholesterol in assessing
cardiovascular disease risk.
Homocysteine
is formed by the body as a naturally synthesized
byproduct of methionine metabolism. Homocysteine,
like cholesterol, is needed by the body
and after
it is used is broken down for other uses such
as ATP and cysteine. If it does not break
down
and enters the bloodstream it will eventually
attack the blood vessel walls causing scaring
and laying the foundation for plaque and platelet
formation, heart disease, stroke and other
cardiovascular
disease. When homocysteine accumulates it causes
oxidation of fats and free radicals causing
platelets to stick together and free radical
damage to the artery walls.
If certain
enzymes, and catalysts are not present,
homocysteine
cannot be properly metabolized by the body.
The absence of these enzymes may be due
to genetic
defects or more often due to nutrient deficiencies
such as B-6, B-12, and folic acid. For
those who do not possess a genetic defect
for
homocysteine breakdown, supplementation with
the deficient nutrients seen with elevated
homocystiene
may be encouraged. People with low levels of
B vitamins and folic acid are smokers and
users
of birth control. Both are linked to high homocysteine
levels and heart disease. Birth control
pills
deplete vitamin B-6 and smokers generally have
low levels of folic acid and vitamin B-12.
Nutrients
that may contribute to lowering homocysteine
levels are (TMG) trimethylglycine, folic acid,
vitamin B-6, and vitamin B-12 although the jury
is not totally out on what dosages of these
nutrients are required to lower homocysteine.
A
multi-vitamin cannot supply the dosages (folic
acid and B-12) of all of the nutrients that
have been found to lower homocysteine levels
however taking a good daily multivitamin and
eating a balanced diet can help to prevent nutrient
deficiencies.
Low cholesterol
food sources of B-6 are legumes, beans, grains,
nuts, fruit and vegetables, B-12 are lean poultry,
meats, and dairy products, folacin are fresh
green leafy vegetables, legumes, peanuts, and
sunflower seeds. Another thing that might help
is the avoidance of too many convenience, highly
processed snack foods that contain hydrogenated
or partially hydrogenated fats and use olive
oil and other sources of monounsaturated fats
for cooking, salads, etc.
I
hope this helped. Please contact me for further information or if you have another question!
