Claimed health benefits of brewed beverage are drawing many people to join the party

Sales of tea are soaring, with green teas, black teas, chais and herbals all hot options to coffee.

But determining which teas to drink —- and which ones are low in caffeine, high in antioxidants and still flavorful —- is about as difficult as, well, reading tea leaves.

Is green tea truly better for you than other teas? Does it contain caffeine? How about yerba mate, the hot drink of celebrities? What about black and red teas? And what is oolong tea, anyway?

"It's so easy to get confused about tea, " said Beverly Hernandez, a registered dietitian at Piedmont Hospital. "Americans are converting from coffee to tea because it contains half the caffeine, and that's good, but people often aren't aware of how much caffeine [various] teas contain."

So let's start at the beginning.

Tea is a warm beverage made from soaking the leaves, roots, berries or seeds of a plant in hot water.

Strictly speaking, a true tea, such as a black or green tea, is brewed from the leaves of a specific type of camellia plant. It is said to have been discovered in China 2,700 years before the birth of Jesus, when a leaf fell into a cup of boiling water that an emperor was purifying. The emperor liked the drink that resulted and believed it to have healing powers.

Yet it's only been in recent years that the drink has taken strong root in this country.

Part of the interest has been fueled by studies about the risks of caffeine —- and the afternoon jitters and nighttime tossing and turning caused by too much coffee. Also, green tea has grown in popularity in recent years because studies have shown that it may cut cancer risk.

White tea, which comes from the bud of the tea plant, has little to no processing and therefore has more antioxidants than even green tea and has less caffeine than green tea. Its popularity is growing, but it's expensive because it is harvested during a very short time in the spring.
