I NEITHER ENDORSE NOR OBJECT TO THE VIEWS EXPRESSED IN THIS BLOG. THEY ARE MESSAGES RECEIVED BY ME AND SIMPLY COLLECTED AT ONE PLACE
Some so called Myths about Choleserol are given in an article given below. It is also said that it is extremely important to
know that part of Cholesterol in our bodies when exposed to UVB
portion of solar radiations, is also converted to much
needed Vitamin D . These UVB radiations are most prominent in early
morning -before 9 AM - solar radiations.
LDL portion of body cholesterol that
is considered main cause of artery blockage can be controlled mainly by
physical exercise and also by reducing saturated fats and Omega
6 unsaturated fats in our diets. It is a misguidance to consider that all
unsaturated fatty acid- manly vegetable oils are good for our health.
Unsaturated fats are good for our health only when the Omega 6 content is equal
to Omega 3 content or at the most twice the Omega 3 content. But pity is
that most vegetable oils consist of more than 90% omega 6 fat only.
Typical US and Indian diets are said have Omega 6 up to 60 times more
than Omega 3.
Only good Olive oil and Grass fed
cow's milk and ghee are said to contain Omega 3 in larger and
desired proportions.
Life insurance
companies know a surprising secret about cholesterol that most doctors never
tell patients: When it comes to rating your risk for a fatal heart attack,
theleastimportant cholesterol number is your level of LDL (bad) cholesterol. In fact, life insurance actuaries don't even look at LDL levels, because large studies show it's theworst predictor of heart attack risk.Instead, life insurance companies use a simple math formula to rate your heart attack risk: They divide your total cholesterol by the level of HDL (good) cholesterol. If the ratio is below three, and there's no inflammation in your arteries, you're practically bulletproof against heart attacks and strokes, even if your LDL is high, reports Amy Doneen, MSN, ARNP, medical director of the Heart Attack & Stroke Prevention Center in Spokane, Washington.Here's a look at eight common cholesterol myths.

If the ratio is below three, and there's no inflammation in your arteries, you're practically bulletproof against heart attacks and strokes, even if your LDL is high, reports Amy Doneen, MSN, ARNP, medical director of the Heart Attack & Stroke Prevention Center in Spokane, Washington.Here's a look at eight common cholesterol myths.
Myth: Cholesterol is
inherently evil.
Fact:You couldn't survive without cholesterol, since
this waxy substance produced by the liver plays many essential roles in our
body, from waterproofing cell membranes to helping produce vitamin D, bile
acids that help you digest fat, and sex hormones, including testosterone,
estrogen, and progesterone.Cholesterol is ferried through your body by
molecular submarines called lipoproteins, such as low-density lipoprotein (LDL)
and high-density lipoprotein (HDL).
Fact: Although low levels of LDL cholesterol
are usually healthy,a new study reports that people who develop cancer
typically have lower LDL in the years prior to diagnosis than those who don't
get cancer.Researchers compared 201 cancer patients to 402
control patients without cancer, matched by such factors as age, gender,
smoking, blood pressure, diabetes, and body mass index. None of the patients
had taken statins.Thirteen earlier randomized clinical trials of
statin therapy also found a link between low LDL and cancer, causing medical
debate about whether statins raise risk. The new study suggests that an unknown
biological mechanism rather than cholesterol-lowering medication may be the
culprit.
Fact: Nearly 75 percent of people hospitalized
for a heart attack have LDL (bad) cholesterol levels that fall within current
recommended targets, and close to half have optimal levels, according to a national study of about 136,000 people. The researchers
also reported that levels of protective HDL (good) cholesterol have dropped in
heart attack patients over the last several years, probably due to the rise in
obesity, diabetes, and insulin resistance. Only 2 percent of the patients
studied had ideal levels of both LDL and HDL.
Fact: The size of the particles matters, says
Doneen. Think of beach balls and bullets. Some LDL particles are small and
dense, making it easier for them to penetrate the arterial lining and form
plaque, while others are big and fluffy, so they tend to bounce off the artery
walls.People who mostly have
small, dense LDL cholesterol are up to three times more likely to have heart
attacks than those with big, fluffy particles.
Fact: Contrary to the stereotype that most of
us are just a few big Macs away from a heart attack, US men rank 83rd in the world in average total cholesterol
and US women 81st, according to the World Health Organization. For
both sexes, the average is 197 mg/dL, slightly below theborderline high range (200 to 239 mg/dL).In Colombia, men average a whopping 244 mg/dL a
level that doubles heart-disease risk while Israeli, Libyan, Norwegian, and
Uruguayan women are in a four-way tie for the highest average with 232.
Fact: Triglycerides, a type of blood fat, don't
invade the artery wall and form plaque, explains Doneen. However, high
triglycerides mark another huge problem: insulin resistance, a pre-diabetic
condition that is the root cause of 70 percent of heart attacks.High triglycerides are also one of the warning
signs of metabolic syndrome, a cluster of abnormalities that multiply risk
for coronary artery disease, stroke, and type 2 diabetes. To be diagnosed with
metabolic syndrome, you must have three or more of these disorders: high blood
pressure, high blood sugar, a large waist, high triglycerides, and low HDL.
Fact: It's true that eggs are high in dietary
cholesterol, with upwards of 200 mg, mainly in the yolk.Research shows, however, that eating three or more eggs a day
boosts blood concentrations of both good and bad cholesterol.The LDL particles tend to be the light, fluffy
ones that are least likely to enter the arterial wall, while the increased HDL
helps keep the arteries clean, suggesting that most people's bodies handle
cholesterol from eggs in a way that's unlikely to harm the heart. The
researchers say that their findings add to growing evidence that eggs are not a dietary evil.
Myth: There are no visible
symptoms of high cholesterol.
Fact: Some people with high cholesterol develop
yellowish-red bumps called xanthomas that can occur on the eyelids, joints,
hands, or other parts of the body. People with diabetes or an inherited
condition called familial hypercholesterolemia are more likely to have
xanthomas. The best way to tell if your cholesterol
is too high is to have it checked every three years, starting at age 20, or
more often, if advised by your healthcare provider.
