Tea as a treatment for attention deficit disorder? If the beverage's other health creds 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.
