Tea improves alertness and brainpower in study
According to a study carried out by Dutch scientists, drinking tea improves brain performance and reduces tiredness. The research focused on caffeine and L-theanine, an amino acid found in tea, and discovered that their combination can prove beneficial in improving cognitive performance. The effects were tested on a group of 44 young volunteers using various mental tasks like word recognition and attention switching. The speed and accuracy of these tasks were significantly improved by the active ingredients, compared to the placebo group. Scientists also found that drinking tea reduced tiredness and fatigue in the group. The research was conducted on behalf of Unilever, the owner of Lipton tea brand.
