Are You Easily Distracted? Try Some Tea!

“Brain in the News” is a weekly commentary on how brain science relates to the news. The brain is involved in everything we do. Wherever there are human stories the brain is involved. From the impact of war and natural disasters on the brain to drug abuse scandals to courtroom dramas to politics the brain is in the news, and you can read about it here.

TEA’S HEALTH CREDENTIALS

The evidence continues to build for the positive health effects of drinking tea. I’ve been speaking for some time about the brain benefits of certain types of teas – now we’re beginning to link tea consumption with specific brain function issues, such as ADD. Here’s a recent article from Newsweek magazine…

Tea as a treatment for attention deficit disorder? If the beverage’s other health credentials aren’t impressive enough—a host of studies have suggested it shields against heart attacks, stroke, diabetes, and possibly some cancers—now comes the news that it may also focus jumpy minds. “We have reports going back thousands of years that drinking tea makes people feel relaxed,” says John Foxe, a professor of neuroscience and an expert on the mechanisms of attention at the City University of New York. “But it also seems to make them more alert.”

The bulk of the research on tea till now has focused on the antioxidants it contains, the flavonols, catechins, and lignans that appear to arm the body against disease. It’s thought that they improve blood vessel dilation, for example, and lower the risk of aortic atherosclerosis. “We know that the more tea one consumes, the stronger the cardiovascular protection will be,” says Lenore Arab, a nutritional epidemiologist at the University of California-Los Angeles David Geffen School of Medicine. By inhibiting damage to dna, some researchers theorize, the antioxidants may also slow tumor growth.

Now neuroscientists are weighing in with evidence that components in the leaves of the Camellia sinensis plant may work wonders in the brain as well. According to Foxe’s research, the amino acid theanine, which is found in green, black, and oolong teas, causes a decrease in the brain’s “alpha rhythms” when people perform complex attention tasks, causing them to pay closer attention. His ongoing research, funded by the food and beverage conglomerate Unilever, suggests that theanine and caffeine together improve performance more than either substance alone. The findings, described in September at a conference on tea and human health, argue for further studies specific to add, Foxe thinks.

Other brain studies are still in the very early stages but offer hope that tea might battle degenerative diseases like Parkinson’s and Alzheimer’s, too. Silvia Mandel, vice director of the Eve Topf and the National Parkinson Foundation Centers in Israel, has found that—in mice, at least—tea’s main antioxidant shows an ability to curb brain cell death and encourage neurons to repair themselves.

Food is medicine and what you eat really does affect your brain and every other part of your body. Many times, even subtle dietary changes can have tremendous effects on brain and body function. If you’re not a tea drinker, give it a try for a few weeks – you may find your world a little more focused and calm.

To Your Brain Health,
