Cholesterol Top 5 myths

American men ranked 83 in the world of the average total cholesterol.Even if you think you know everything there is to know about cholesterol, there may be a few surprises in store. Discover these common myths about high cholesterol; Discover who is most likely to do so, what types of food can cause and why - sometimes - cholesterol is not a bad word.
Myth 1: The Americans have the highest rate of cholesterol in the world
A lasting stereotypes in the world is the American fat with clogged arteries of cholesterol which is a Big Mac or two not a heart attack. As a nation, we can certainly use some slimming down, but when it comes to cholesterol we are solidly centrist.
The cholesterol Inflammation connectionInflammation is partner of cholesterol in crime moreAccording of reading to the world Organization of the 2005 health statistics, men Americans rank 83 in the world in average total cholesterol, and American women rank 81st; in both cases, the average number is 197 mg/dL, just below the Borderline-high risk category. It is very respectable compared with the top countries: in Colombia the average cholesterol in men is a dangerous 244, while women in Israel, the Libya, the Norway, and Uruguay are locked in a four-lane at 232 tie.
Myth 2: The eggs are evil
It is true that the eggs have much dietary cholesterol - more than 200 mg, which is more than two-thirds of the recommended limit of the American Heart Association of 300 mg per day. But dietary cholesterol is not nearly as dangerous as was once thought. Only some dietary cholesterol ends by as cholesterol in your blood circulation, and if your intake of dietary cholesterol increase, your body compensates by producing less cholesterol than its own.
While you do not want it discourages, eat an egg or two a few times a week is dangerous. In fact, eggs are an excellent source of protein and contain unsaturated fats, a so-called good fat.

Lower cholesterol can reduce the risk of some Cancers

(Thursday, 5 November canstar) - most people know that healthy cholesterol levels can help protect your heart. But new research suggests another potential advantage: less risk of developing certain types of cancer.

In fact, the low levels of total cholesterol is associated with about 60% less risk of the most aggressive form of prostate cancer, and higher levels of good cholesterol (HDL) can protect them against the lungs, liver and other cancers, according to two studies published this week in the journal Cancer Epidemiology, biomarkers & prevention.

This is a reverse of fortune for low cholesterol, which has in the past, been associated with a higher risk of cancer. New studies suggest that low cholesterol does not deserve its bad reputation, received a series of studies in the 1980s, said people with low cholesterol might be at risk of cancer.

In fact, lower cholesterol in people with cancer not diagnosed, which means that the low cholesterol may be a result - not a cause - cancer.

In the first study, men with above at about 55 mg/dL HDL cholesterol had an 11% decrease in overall cancer risk, including cancer of the lung and liver. (Between 40 and 50 HDL levels are average for men). The study, conducted by researchers of the National Cancer Institute (NCI) which focused on a period of 18 years, approximately 29,000 male smokers in Finland is more important to show a relationship between HDL and cancer.

"Very few measured studies [HDL], and any relationship between HDL and overall cancer risk has therefore not been adequately assessed," Demetrius Albanes, MD of the NCI, the principal author of the study, said at a press conference.

While the findings are new and intriguing, research must be carried out to confirm a link between the reduction of the risk of cancer and HDL.

"He has a new, exciting question, but we must do much more research before that we have clear answers," said Eric Jacobs, PhD, epidemiologist of the American Cancer Society, who has co-authored an editorial accompanying the studies. For his part, Dr. Albanes pointed out that the results should be confirmed, especially among women and non-smokers.

Cholesterol supplements: what works, what is not

If you are looking for a natural way to lower your cholesterol - watch what we eat and exercise - there are many dietary supplements on the market that claim to be the case. Each year seems to bring a new action - garlic, ginseng, or red rice yeast, for example - that users like the best thing for cholesterol under control.
But just because your Uncle Jack, says a supplement miracles worked his cholesterol does not mean that it will work for you. In fact, its success may be due to a placebo effect or a redesign of diet, he failed to mention.
Although not always perfect scientific studies are the best way to determine if nonprescription remedies really work. Below, we break down what the research - and doesn't - say about benefits most popular alternative remedies to lower cholesterol.
To see what these supplements look like, view this slideshow.
Artichoke leaf extract
• What it is: the leaf of artichoke dry extract is also known under the name of Cynara scolymus.
• Evidence: in 2000, German researchers conducted a randomized, double-blind, placebo-controlled using almost 150 adults with total cholesterol, more than 280 - until the American Heart Association (AHA) considers the territory "high risk". The participants who took a supplement of artichoke six weeks saw their levels of low-density lipoprotein (LDL) or bad cholesterol, 23%, on average, against only 6% in the placebo group.
These promising figures are, but they have not been replicated. A more recent test, three months of similar design revealed that total cholesterol dropped by an average of 4% in participants taking Artichoke leaf extract, but researchers have not found no measurable impact on LDL or high density lipoprotein (HDL), also known as the good cholesterol. They suggested that the differences in the health of the participants and the power of supplements - in the second study patients received a dose of approximately 30% smaller - could explain the difference between the results of two studies.
• The bottom line: it there has had very few quality studies on leaves of artichoke extract, and the mixed results suggest that evidence more is necessary to confirm its effect on cholesterol. Don't expect your LDL down if you take supplements of artichoke.
Fenugreek
• What it is: fenugreek is a seed (often on the ground powder) which has been used since the days of the old Egypt and is available in capsule form.
• Evidence: several studies since the 1990s have reported that, in high doses, various preparations of fenugreek seed can lower total cholesterol and LDL, in some cases considerably. (Une study registered a decline of 38 LDL. Almost without exception, however, the studies were small and of poor quality, which casts doubt on the validity of the results.
Fenugreek contains a significant amount of dietary fiber (anywhere from 20% to 50%, analyses have shown), and some experts believe that the effect of cholesterol alleged fenugreek in fact can be attributed in large part to its fibre content.
• The bottom line: despite studies frequently cited as evidence of the ability of fenugreek to lower cholesterol, there is not enough evidence to support its use.
Fibre
• What it is: Soluble Fibre is a type of dietary fibre found in oats, barley, bran, peas and citrus, as well as in food supplements. (Even if it's good for the heart by other means, the insoluble fibres do not affect cholesterol in the blood.)
• Evidence: in 1999, a team of researchers from Harvard Medical School conducted a meta-analysis of close to 70 clinical trials that examined the effects of the soluble fibres on cholesterol levels. High in soluble fibre intake was associated with reductions in LDL and total cholesterol of 60 to 70% of the studies they examined. For each gram of soluble fiber the participants of different studies added to their daily diet, their LDL levels fell by about 2 points. (The average time was seven weeks).
The amount of fibre, you need to eat significantly lower your LDL is a little difficult to handle. Most people eat much less that 25 grams of fibre recommended at least by most organizations of health - and that approximately 20% of your fibre consumption total is likely to be soluble. (Three bowls of porridge to eat a day gives approximately 3 grams of soluble fiber, according to the Harvard researchers). Taking fibre supplements daily can help, but they can cause gastrointestinal side effects if taken regularly, and may interfere with certain prescription drugs.
• The bottom line: a diet high in soluble fibre can reduce your LDL. However, the effect is likely to be relatively modest, and loading on the soluble fibres may be impractical.

Menopause Causes cholesterol Jump, Study Shows

Friday, December 11, 2009 (canstar) - doctors have known for years that risk of women develop heart disease rises after menopause, but they were not sure exactly why. It is not clear whether if the increased risk is due to the changes associated with menopause hormones, aging itself, or a combination of both.

Now we have at least a part of the answer: a new study shows beyond doubt that menopause, not the natural aging process, is responsible for a strong increase in cholesterol.

This seems to be true of all women, regardless of ethnic origin, according to the study, to be published next week in the Journal of the American College of Cardiology.

"As they approach menopause, many, many women show a very striking increase in cholesterol levels, which in turn increases risk of heart disease later", explains the main author of the study, Karen a. Matthews, Ph.d., Professor of Psychiatry and epidemiology at the University of Pittsburgh.

Over a period of 10 years, Matthews and his colleagues followed 1 054 United States women as they went through menopause. Each year, researchers tested participants in the study for cholesterol, the pressure blood and other risk factors for heart disease, such as insulin and blood glucose.

In almost all the women, the study concluded, cholesterol jumped at menopause. (Menopause usually occurs around age 50 years but may occur naturally earlier than 40 and no later than 60).

In the window two years surrounding their final menstrual period, LDL women average or bad cholesterol, rose by about 10.5 points, or about 9%. The average of the level of total cholesterol have also increased significantly, by approximately 6.5%.

Other risk factors, such as insulin and systolic blood pressure (the top number in a blood pressure reading), has also increased over the study, but they did at a steady rate, suggesting that increases - unlike those for cholesterol - were related to aging, not menopause. All factors measured in the study risk, cholesterol changes were the most spectacular.

Jumps in cholesterol reported in the study certainly have an impact on the health of the woman, said Vera Bittner, MD, a Professor of medicine at the University of Alabama at Birmingham, who wrote an editorial accompanying the study of Matthews.

"Change look not great, but given that the typical woman lives several decades after menopause, any adverse change become cumulative time, says Dr. Bittner." "". If someone had cholesterol levels in the lower ranges of normal, small change can not make a difference. But if someone's risk factors were already borderline in several categories, this increase may make them look at the edge and put them in a category of risk where treatment may be beneficial. »

First, the study does any measurable difference in the impact of menopause on cholesterol between ethnic groups.

Experts have been uncertain how ethnicity may affect the link between menopause and cardiovascular risk, because most of the research to date have done in the white women. Matthews and his colleagues were able to explore the role of ethnicity, because their research is part of the largest study of women health across the Nation (SWAN), which includes a significant number of African-American women, Hispanic and Asian American.
