The headline “forget coffee – green tea holds the key for men”, is an eye-catching, but misleading, extrapolation of the results of this study. However, reporting that soft drinks containing green tea may cause small changes in blood flow in the brain , but do not seem to help in performing memory tasks, was perhaps seen as less headline-worthy. However, it also showed that this did not affect performance in a working memory task that volunteers performed each time their brains were scanned. The researchers found that drinking a soft drink laced with green tea extract appeared to increase blood flow to a part of the brain called the dorsolateral prefrontal cortex .
