Various Types of Tea and Its Benefits

Various types of tea are not only offers a different flavor, but also a variety of health benefits. There is a type of tea is good for bones and teeth, some are specifically recommended for weight loss.

The benefits of each type of tea are as follows, as quoted from Dailymail, Tuesday (03/08/2011).

1. White tea for skin care
Highest antioxidant content can be found in White Tea made from tea plant shoots. In addition to preventing premature aging effects, high antioxidant in White Tea can also prevent wrinkles by protecting the two proteins that maintain the skin elasticity of elastin and collagen.

2. Rooibos tea to overcome the lack of blood
Symptoms completely exhausted from lack of blood can be treated with rooibos tea, herbal tea from South Africa that was made from the bushes. These teas contain at most tennin, flavonoids are able to increase the absorption of iron from food.

3. Oolong tea to prevent cavities
Types of herbal tea from China is at most contain catechin, antimicrobial compounds that can prevent caries or cavities. Other types of tea that has antimicrobial activity which is close to Oolong tea, is the Black Tea.

4. Chamomile tea to keep blood pressure
According to a study in Japan, consumption of Chamomile tea without sugar every day can prevent the risk of diabetic complications. One is the increase in blood pressure that can lead to nerve damage and impaired vision.

5. Black Tea for bone strength
Compared to other types of tea, Black Tea also called Cuppa Tea has the most diverse benefits. The most powerful addition to relieving stress and cholesterol levels, Black Tea is also good for bones because it is rich in minerals manganese, and fluoride.

6. Green Tea for slimming
Japanese study proves, drink a cup of green tea every day can increase food metabolism in the body. This type of tea contains epigallocatechin gallate at most, a compound that can shed fat and bad cholesterol.

The Reason for the Difficulty of Implementing Dietary

Not easy to do a diet to lose weight. Some people sometimes have specific reasons to avoid it. What is it?

Most people would think several times before finally deciding to diet. When thinking that sometimes arise for reasons they did not have to go on a diet.

Here are some common reasons that a person said to avoid the necessity for the diet, namely:

1. ‘Tomorrow I will start a diet’
Most people procrastinate on a diet by saying tomorrow. And if a person was serious about dieting, they would immediately begin that same day without exception.

2. ‘I really liked food’
Everyone will love to eat, so it is not the right reasons. Someone who dieter can still enjoy the food, but the amount that must be considered so as not to overdo.

3. ‘Healthy food is expensive’
The reason this is not true, because they do not need to choose an expensive diet food. The thing to do is eat healthy fresh foods such as fruits, vegetables, lean meat that is actually less expensive than processed foods.

4. ‘I do not have time’
Everyone do not need to do for hours to go on a diet, but only briefly, and even no more than 30 minutes. If they already have the will, then all things must be done.

5. ‘I can not work when I’m hungry’
A good diet will not make a person hungry, but instead make it more active and productive so that they can think better because eating fresh foods without preservatives and malnutrition.

6. ‘Condition has been derived from families’
Some people try to hide the fat on the grounds of the family genes. But the researchers found that obesity is not a dominant gene so that a person can still control their weight with some effort.

7. ‘I do not like fruit and vegetables’
If you do not like to be consumed raw, the vegetables can be added to the soup, stew or other food mixtures, while fruit can be made juice or good smoothies.

8. ‘My job, a lot of traveling, so I have a lot to eat’
This condition can be overcome with smart food choices like low-fat, for example, choose steamed fish or chicken and salad with honey and lemon to replace the mayonnaise.

Nothing says that the diet program is easy to do, but by eliminating the reasons, a person is one step closer to success.

Breast Cancer Risk for Former Smokers

Women who have ever smoked had a risk of developing breast cancer is greater in old age. Even if they had stopped 10 years though, the risk is still great.

A study reveals, 16 percent of women after the age of menopause susceptible to disease, especially those who smoke. The earlier a woman starts smoking, the greater the risk. And the risk is still high even though they had stopped for 20 years. Generally, if they are smokers the risk is the potential to reach 9 percent.

This fact is the result of research conducted by doctors Juhua Luo of the University of Virginia and physician Karen Margolis from HealthPartners Research Foundation, Minneapolis, United States. They studied data collected from 1993 to 1998 who took the sample of 80,000 women aged 50-79 years.

The study also studying secondhand smoke. For passive smokers risk of cancer to 32 percent, especially if they are exposed to smoke from childhood.

In the study continued 10 years later, the researchers found 3,250 cases of malignant cancer that affects the object of study participants.

They were given a few questions about their status as a smoker, and as a passive smoker.

As a result, smokers who had entered menopause are at increased risk of cancer by 16 percent. While those who had quit smoking the risk is 9 percent. The biggest cancer risk experienced by those who smoked for 50 years or more.

Doctor Margolis said the results of this study is an attempt to prevent women smoke, especially those still in an early age. Doctor Rachel Greig, Senior Policy Officer at Breakthrough Breast Cancer says the earlier the woman smokes and the longer it continued the habit, the greater the likelihood of developing breast cancer. “We encourage all women do not smoke,” she said.

World’s First Optical Microscope that could view 50 nanometers objects

Image: DailyMail

England created a new type of optical microscope that is able to break the record to saw the smallest object that can’t be seen on ordinary optical microscope.

Scientists from Univesity of Manchester and colleagues from Singapore to introduce new optical microscope that can help learn the many viruses that cause disease. The findings were published in the journal Nature Communication.

“This world’s first optical microscope can view objects 50 nanometers under normal light and it is a new record,” said the Wang Zengbuo, author report. Previously, the microscope could not see objects as small as it is because of interrupted light.

For going beyond that, scientists combining optical microscopy with micro transparent ball, dubbed ‘micro ball nanoskop’. Using a more powerful force, a new creation that can be used observe the contents of human cells and virus for the first time.

Further, the principles used microscopes that can be used to produce a more powerful optical microscope. “Not only see objects 50 nanometers, we believe it is only the beginning and could see much smaller objects again,” said senior author Li Lin.

In theory, no limit on how small an object can be seen, added Li. Microscope that there are currently only able to see the cell surface and could not see its structure. In addition, there is no tool to see virtually immediate virus.

Some scientists use the ‘optical fluorescence microscope’ to look into the cells indirectly by coloring them in advance. However, this technique can not penetrate the virus.

Therefore, scientists believe, this new microscope has the potential to revolutionize the way cells and study the vius. This will be very helpful in biomedicine and treatment of a disease.

Toenails Cut Predict the Risk of Lung Cancer

A study showed that the toenails cut can be used to predict the risk of lung cancer several years before it developed.

Measurements of nicotine levels in toenails cut it found the men with the highest readings three times more likely to get cancer than the lowest.

Because toenails grow so slowly – 1 cm a year – they provide important information about long-term exposure to cigarette smoke.

The findings, by scientists at the University of San Diego in California, it could pave the way for doctors to detect lung tumors.

Toenails are not only identified as most at risk smokers but also non-smokers, says the study in the American Journal of Epidemiology. This means providing guidance to the damaging effects of passive smoking.

The researchers took samples of nail cut from 850 men and followed them for more than 12 years to see who developed lung cancer.

They estimate that people with the highest nicotine levels of 3.5 times more likely to suffer from cancer 12 years later compared with those with the lowest levels.

Lung cancer kills less than 30 thousand people a year in England and Wales and smoking causes about 90 percent of cases.

It is estimated that people who smoke more than 20 cigarettes a day 20 times more likely to get it than non-smokers.

Figures released earlier this week showed levels more than doubled for women over 60 since the mid-1970s.

The disease is now attacking 190 in every 100,000 women, up from 88 per 100,000 is almost 30 years ago. Experts blame the fact that smoking peaked in women during that period.

Meanwhile, the rate of disease among men has decreased since smoking has declined in popularity in the 1970s.

Toenails grow about one centimeter a year so it can provide important clues about the long-term exposure to cigarette smoke.

Samples were taken from each volunteer at the beginning of the experiment in 1987 and analyzed the level of nicotine. The men were then followed to 12 years to see which one is suffering from lung cancer.

The results showed lung cancer victims have nicotine levels on average 12 years earlier around 0.95 nanogrammes per milligram. But they are free of cancer has only 0.25ng per milligram.

The study shows nicotine levels nails provide biomarkers that can predict the risk of lung cancer independent of smoking history were reported.

Waist Circumference Affects the Risk of Stroke?

Excessive waist circumference has been known to increase risk of cardiovascular disease. However, from recent studies also found excess waist circumference also increases the risk of TIA and stroke.

Dr. Tobias from Saxon Hospital recommends that physicians measure waist circumference and waist-hip ratio using (which was created by WHO) to assess the risk of stroke.

Also emphasized the importance of assessing overall vascular risk profile, the point to minimize or modify the factors that affect coronary heart disease, stroke and peripheral arterial disease.

The research team is evaluating the role of obesity and abdominal fat mass to the risk of stroke / TIA in 378 adults with a history of stroke / TIA and 758 subjects as controls. In the adjusted analysis, several markers of abdominal obesity are strongly associated with risk of stroke / TIA. For example: someone with waist-hip ratio had the highest risk of 7.69 times more to suffer from the incident, compared with patients who have the smallest ratio.

If the waist-hip ratio> 0.97 in men, and> 0.85 in women, they have 8 times more risk to the risk of stroke, when compared to someone else with a ratio <0.92 in men, and <0.78 in women. waist circumference was also strongly associated with stroke / TIA. If waist circumference> 40.2 inches for men and> 34.6 inches for women, the risk of stroke increased by 4 times.

This study also showed that waist-height ratio (waist circumference divided by height) can also be used to assess the risk of stroke and TIA, which is comparable to the size of waist circumference. However, further research is still required to ensure where the best markers in predicting the risk of cerebrovascular specific or total.

This study also shows that markers of abdominal adiposity was the best predictor for stroke / TIA than BMI. By using different statistical calculations, confirmed that the waist-hip ratio seems to be a risk of stroke/TIA.

Stable Levels of Good Cholesterol (HDL) have Relatively Long Life

Research shows, the quality of a man’s health can be determined also by the levels of cholesterol in their blood. Those who are able to maintain stable levels of good cholesterol or HDL, relative has a long life.

According to researchers at the Boston study published the American Journal of Cardiology, the man who is able to reach the age of 85 years tend to have high HDL cholesterol levels while in their 60s. Men of his HDL highest risk of less than 28 percent died at age 85, compared with men with HDL levels was the lowest.

Dr. Nir Barzillai from the Institute for Aging Research at Albert Einstein College of Medicine in New York, U.S., believes the results of this study add to evidence that cholesterol plays an important role in determining the quality of one’s health.

“We must always remember that this is a relationship, and it does not mean having a high HDL can increase life expectancy,” said Barzillai.

According to the American Heart Association, about 12 million people in the land of Uncle Sam suffering from heart disease and stroke by the year 2006. But the risk of heart problems can actually be lowered by maintaining HDL cholesterol levels remain high. HDL levels are low, less than 40 milligrams per deciliter (mg / dL) in blood, as long as it is also known to increase risk of heart disease.

Decreased risk of Scientists from the Massachusetts Veterans Epidemiology Research and Information Center in Boston, USA, conducted a review of medical records of 650 veterans when they were aged about 65 years. Later, these veterans can be sorted by their HDL levels.

Starting from the lowest level that is 40 mg / dL, the researchers found that each 10 mg / dL increase in HDL, a man has an 14 percent reduced risk of dying at age 85. Overall, there are 375 veterans who survive past the age.

In addition, there were few men of her high HDL levels who are overweight and among those likely to drink alcohol does not exceed two drinks a day. Among them are also less likely to have heart problems and smoking, than in the low HDL group.

According Barzillai these factors also may affect the durability of the men. Even so, the researchers did not consider these factors, and and the results of the study showed a strong relationship between attainment of age 85 with high levels of HDL.

Barzillai add, to alter HDL levels in the body is not easy. Exercise may help, but now there is no way the most efficient way to improve HDL levels. “At the end we may need medication,” he said.

According to the Mayo Clinic, one type of supplement intake of vitamin B that niacin may help boost HDL levels between 15 to 35 percent. However, there is a risk that sempingnya effect on liver damage and increased blood sugar. But there is also a natural source of niacin that is made from dairy products, lean meat, beans, eggs and fish.
