4 The Best Tea for Health

Tea is synonymous with health. Habit of sipping a cup of tea is also effective to reduce stress, prevent hypertension, to reduce the risk of heart disease. There are different kinds of tea in the world, but in general there are four types of tea which properties should not be underestimated.

1. Darjeeling

Tea is touted as the world's best tea is picked from the tea plant that grows in the Himalayas in the Darjeeling region of India.

A recent study found the benefits of tea to inhibit the growth of pathogens that can cause pain H.pylori gastritis, peptic ulcers, and cancer colon. And, among the tea is Darjeeling tea was a direct positive effect on a five-minute intervals after drinking. To optimize the effect, avoid consuming tea mixed with milk.

2. Oolong Tea

Also referred to as semi-fermented tea. Oolong tea is very wide variation, from mild and sweet, until the tea is more strong and bitter.

According to a study of more than 1,500 subjects, those who drank two and a half cups of oolong tea or green tea every day, the risk of high blood pressure 46 percent lower. Oolong and green tea rich in antioxidants are effective to control the enzyme triggers an increase in blood pressure.

3. Black Tea

When the tea leaves left to ferment until the whole, they will turn into black tea, although the actual color is closer to red.

Many people prefer to have a healthy green tea, black tea but not less antioxidant. Four components of the antioxidants in black tea are known to protect brain from damage by way of specifics. Last year researchers from Germany revealed that black tea can protect the process of plaque formation in the brain that trigger Alzheimer's disease.

4. Yerba Mate

Derived from the leaves of plants that are considered sacred by the natives of South America, yerba mate herb belonging to the powerful. To reduce bitterness, yerba mate leaves enter into the warm water (not boiling).

Research in 2011 showed, yerba mate has the ability to destroy cancer cells. Components in tea, including caffeine, can damage the DNA of cancer cells.

Caffeine Can Help Strengthen Muscles

Scientists claim that caffeine consumption may help improve muscle function, particularly in the elderly. Increased muscle function will help to maintain strength, reduce the risk of falls and injuries. The findings will be published on June 30, 2012 in the Society for Experimental Biology.

Sports Experts from Coventry University to see for the first time whether the effects of caffeine consumption associated with changes in muscle. The result is known that caffeine continue to improve muscle performance in rats, although less visible effective in older muscle.

In his study, the researchers isolated muscle from mice ranging in age from teenagers to senior citizens. Muscle performance and then tested before and after the mice were given caffeine. Researchers looked at two different skeletal muscles. The first is the diaphragm, the core muscles used for respiration, and the second is called the leg muscles extensor digitorum longus (EDL), which is used to move.

"Although the effect tends to decrease in muscles of older rats, consumption of caffeine may still provide benefits," Jason Tallis, principal investigator for the research.

For young adults, consumption of caffeine contributes to help the muscles to produce more power. But with age, our muscles will naturally change and become weaker.

Researchers said the effects of caffeine consumption are not very visible in young muscle. This may be because the muscles are still growing, so the effect of caffeine consumption is not too much difference.

Decrease in muscle strength with age contributes to trigger a wound or injury, and reduced quality of life. Researchers say that they do not know exactly how the mechanism of action of caffeine in increasing muscle strength. But it is clear that the key to keeping the muscles to remain strong is to keep active and maintain a healthy lifestyle.

"It is important to maintain the lifestyle to stay physically active to maintain health and functional capacity. Improved performance of caffeine can provide evidence of benefit in the process of aging," said Tallis.
