Popular Japanese tea matcha has health benefits

Matcha, finely ground powder made from baby green-tea leaves, is growing in popularity due to health benefits and the natural woodsy flavor it imparts to drinks, pastries and savory dishes, reported Jenice Tupolo and Carla Meyer in the Sacramento Bee

To find out if the most-prized tea in Japan lives up to its purported health benefits when scrutinized scientifically, the reporters contacted UC Cooperative Extension specialist Sheri Zidenberg-Cherr.

“The health benefits are similar to that of green tea in general,” Zidenberg-Cherr said. Possible benefits of green tea include lower risk of cardiovascular disease and some types of cancers, and bone-density improvement. Though "the studies are pretty inconclusive," she said, some have been promising.

"Some have shown a benefit of maybe three cups a day in terms of reduced risk of cardiovascular disease especially," she said.

Zidenberg-Cherr cautioned against taking matcha or green tea with dairy milk.

"There is a protein in cow's milk that will bind to those important catechins and reduce how much you actually get in your body," she said.

Children tend to get too much caffeine

Many parents are unaware their children are consuming too much caffeine, University of Nebraska Medical Center researchers found, and it is not good for their health, according to a post on the "contributed news" website All Voices.

The medical center surveyed the parents of more than 200 children 5 to 12 years old during routine clinical visits at an urban pediatric clinic. The researchers found that 75 percent of the children consumed caffeine on a daily basis, and the more caffeine the children consumed, the less they slept.

Children as young as 5 years old were consuming the equivalent of a can of soda a day. Children between the ages of 8 and 12 years consumed an average of 109 mg of caffeine a day, the equivalent of almost three 12-ounce cans of soda.

The All Voices post referred readers to a UC Davis nutrition and health info sheet titled "Some Facts About Energy Drinks," written by project scientist Karrie Heneman and Cooperative Extension nutrition specialist Sheri Zidenburg-Cherr.

The fact sheet said the caffeine content of a single serving of energy drink (8 to 12 oz.) can range from 72 to 150 mg, however, many bottles contain 2 to 3 servings, raising the caffeine content to as high as 294 mg per bottle. In comparison, the caffeine content in an 8-ounce serving of brewed coffee, tea and cola ranges between 134-240 mg, 48-175 mg and 22-46 mg respectively.

Other stimulants such as guarana and ginseng are often added to energy beverages and can enhance the effects of caffeine. Guarana, in particular, contains caffeine (1 g of guarana is nearly equal to 40 mg caffeine) and may substantially increase the total caffeine in an energy drink.

The more caffeine children consume, the less they sleep.
