Jewish World Review
Green tea is popular. Should it be?

Sipping a cup of green tea, whether hot, cold, or as a bottled beverage, is becoming increasingly popular for Americans intake has more than doubled in the past four years. Today, you can find green tea in everything from shampoo and face creams to muffins and ice cream.
Popular in Asia, this plant-based beverage has a lot to offer: a bold, exotic flavor profile, a light nutritional profile with zero calories, and an increasing body of research demonstrating potential health benefits.
READING THE TEA LEAVES
Green tea, like black and oolong tea, is made from the leaves of the Camellia sinensis plant. What makes green tea unique is that the mature tea leaves are steamed, rolled, and dried directly after picking without allowing for oxidation, producing a tea that tastes closest to the fresh leaves. In contrast, black and oolong tea leaves are oxidized, which turns the leaves brown and produces their strong flavor. | FREE SUBSCRIPTION TO INFLUENTIAL NEWSLETTER | | Every weekday JewishWorldReview.com publishes what many in the media and Washington consider "must-reading".

Scientists have identified high levels of compounds in brewed teas called catechin flavonoids, which possess anti-inflammatory, antioxidant and anticarcinogenic effects. Green tea, in particular, contains the catechin epigallocatechin gallate (EGCG), which may be at the root of green tea's health benefits.
PROS AND CONS
A number of health bonuses, from strong teeth to bone protection, have been attributed to green tea, but not all of the studies have produced positive results. Here's a look at some of the most intriguing findings:
1. Cancer. Studies show that green tea may inhibit the development of cancer in animals; it's been linked with protection at many sites, including skin, lung, mouth, stomach, colon, pancreas, bladder, and prostate. Human studies have shown inconsistent findings, and the doses of green tea in studies have varied. However, a 2012 Japanese study found that 10 cups per day was a significant factor in primary cancer prevention for the general population.
2. Heart disease. Tea drinkers seem to have a lower risk of heart disease; for every three cups consumed each day, the risk of heart attack drops by 11 percent, according to a meta-analysis in the American Journal of Epidemiology. Up to 10 cups of green tea daily have been found to lower cholesterol, "bad" LDL cholesterol, and triglyerides, and raise "good" HDL cholesterol. But not all studies have found such positive effects.
3. Weight loss. Much attention has focused on green tea's "fat-burning" power. Researchers from the Netherlands reported in a 2010 issue of the International Journal of Obesity that green tea may increase energy expenditure by four to five percent and fat oxidation by 10 to16 percent. However, the science is inconsistent in this area.
LOOK TO THE FUTURE
We need more research on the benefits of green tea before we can understand its full health potential; fortunately, several human trials are underway. In the meantime, there doesn't seem to be a downside for sipping green tea, unless you are sensitive to its caffeine content green tea contains 9 to 50 milligrams (mg) per cup, compared to coffee's 72 to 130 mg.
