Stress and Pollution Can Make Evil Rises Cholesterol

Stress, pollution and bad cholesterol!! What to do? It turns out the three unrelated. Interrelated and mutually trigger. Stress and pollution are two of the many factors that can add breeding "collection" bad cholesterol in the body. 

We recognize stress as a cause of the disease is, so it is definitely. Undeniable. Also been long known. And recent findings stated that due to job stress can alter the way the body metabolizes fat.

This condition can lead to increasing levels of "bad" cholesterol or low density lipoprotein (LDL) and raises the risk of heart disease. An expert in Spanish research found that stressful situations can affect the way the body metabolizes fat, which ended in LDL cholesterol levels soaring.

Previous research experts say, the emotional stress associated with the risk of cardiovascular disease which is the result of unhealthy habits such as smoking, unbalanced diet, lack of physical activity, and other factors.

Previous research experts say, the emotional stress associated with the risk of cardiovascular disease which is the result of unhealthy habits such as smoking, unbalanced diet, lack of physical activity, and other factors.


However, the results of this new study suggests that stress can trigger dyslipidemia, namely the transfer of impaired lipid and lipoproteins in the blood.

Researchers from the Hospital Virgen de la Victoria in Malaga and Santiago de Compostela University analyzed the relationship between work stress and other parameters related to how fatty acids are metabolized by the body.

The study, published in the Scandinavian Journal of Public Health has analyzed on a population of more than 90,000 employees who carry out medical examinations.

One of the researchers Carlos Catalina, who is also a clinical pskilog and experts in the field say job stress, workers who have difficulties in their work during the past 12 months have a higher risk of dyslipidemia. The number of participants who experienced stress in this study is as much as 8.7 percent.

Dyslipidemia resulted in increased levels of total cholesterol and "bad" cholesterol and triglycerides. It also resulted in decreased levels of "good" cholesterol. Study finds more displidemia risk was found in those stressful work.

High levels of "bad" cholesterol and triglycerides, and low levels of "good" cholesterol increases the risk of plaque forming in the arteries that lead to hardening of the arteries. Hardening of the arteries increases the risk of cardiovascular disease.

In another study with a different theme turned out to exposure to pollution is not only bad for the lungs but can also change the "good" cholesterol (high-density lipoprotein / HDL) to "bad". Such changes contribute to the blockage of the arteries that increases the risk of heart disease.

The research team consisting of scientists from the University of California, Los Angeles (UCLA) and other institutions found inhaling smoke pollution may alter the structure of HDL in the body. In addition, these activities also activate other components that cause oxidation damage to cells and tissues premature triggering inflammation and hardening of the arteries.

The study, published in the journal Arteriosclerosis, Thrombosis and Vascular Biology conducted a study on mice. The first group of rats exposed to fumes a few hours per day, for two weeks. The first group of rats subsequently placed for a week in the cage with the air that has been filtered.

The second group with the same treatment, but not placed in cages with filtered air. While the third group was given only exposure to filtered air for two weeks.

Mice that received exposure to fumes have oxidative damage in the blood and heart. Even this damage can not be repaired after being given a clean air exposure is performed on the first group.

Senior study author Dr.. Jesus Araujo, professor of medicine and director of environmental cardiology at the David Geffen School of Medicine at UCLA, said this study shows air pollution can increase HDL dysfunction and activate internal oxidation pathway. Consequently, obstruction of vessels that got so bad that trigger heart disease and stroke.

Particle emissions from vehicle fumes enveloped found chemicals sensitive to free radicals. These particles are known to cause oxidation.

Author of the study and a researcher in the division of cardiology at the Geffen School of Medicine at UCLA recommends people limit exposure to air pollution to reduce the negative impacts.

Hot Drinks Prevent Stroke?

Drinking hot beverages in the morning, whether it's tea or coffee, a part of the daily routine of many people. Simple habits turned out to help us reduce the risk of stroke.

A study of 83,000 people in Japan showed that those who frequently drank green tea or coffee per day had a risk of stroke 20 percent lower. Even the protective effect against certain types of stroke is greater.

 
"If you can not change your lifestyle, try to prevent stroke by regularly drinking green tea every day," said Dr.Yoshihiro Kokubo of National Cerebral and Cardiovascular Center, Osaka, Japan.

Although it was not clear why coffee and tea had the effect of preventing stroke, but according to Kokubo it may be associated with the ingredients in these drinks that keep blood clots.

In addition, green tea contains catechins, which have antioxidant and anti-inflammatory effects. Some of the substances in coffee, such as chlorogenic acid also reduces the risk of stroke by lowering the risk of diabetes mellitus.

The content of caffeine in coffee also have an effect on cholesterol levels and blood pressure. It also led to changes in insulin sensitivity that affect blood sugar.

Even so, according to Dr.Ralph Sacco, a former American Heart Association priseden, such as the type of research conducted Kokubo can not accurately ascertain whether the reduction in stroke risk was indeed derived from the consumption of coffee and tea.

"The link is visible from such studies are limited in their ability to indicate whether content in coffee, tea, or indeed the lifestyle of the respondents who have a protective effect," says Sacco.

Olive Oil can prevent the risk of stroke

Elderly people who consume olive oil have a lower risk of stroke than those who did not drink, researchers said in a study released on Wednesday (15/6) in the United States.

Some scientists at the National Institute of Health and Medical Research in Bordeaux, France, following the development of the 7625 French people aged 65 years and above, of the three major cities - Bordeaux, Dijon and Montpellier - for five years.

During the study, there were 148 people who had a stroke. Research object is divided into several groups according to their actions using olive oil, from people who do not use them at all until they are used in serving food, cooking and baking.

When the researchers adjusted for factors such as body weight, physical activity and food overall, they found they were called olive oil users "intensive" had a 41 percent lower risk of having a stroke than those who never consume olive oil.

"Our research shows a new series of food advice should be issued to prevent stroke in people aged 65 years and above," said the study's lead author, Cecilia Samieri, as reported by AFP.

Meanwhile, Dr. Nikolaos Scarmeas, a neurologist at Columbia University Medical Center in New York who wrote an editorial published with the study, said: "We need to remember this is an observational study."

The study found an association between the use of olive oil by humans and they face the risk of stroke, says Scarmeas told Reuters Health, which monitored ANTARA here on Thursday. But, he said, it does not necessarily translate into causality.

"People who consume olive oil may be very different from people who do not use it," said Scarmeas. Users olive oil, for example, may have higher incomes, eat better overall or more exercise than those who never consume olive oil.

The researchers in the new study, led by Cecilia Samieri, tried to account for that difference. And once they did, it proved oil zaitu linked to lower risk of stroke.

But Scarmeas said that was unlikely to fully account for all the variables. What is needed, he says, is a clinical trial, the object of study were randomly assigned to use olive oil or not, then followed its development from time to time to see who suffered a stroke.

Such clinical trials are seen as the "gold standard" of medical evidence.

"Stroke is common among older people and olive oil would be an easy and inexpensive way to help prevent it," said Cecilia Samieri.

The findings are published in the journal Media American Academy of Neurology, "Neurology".
