Tea (Camellia sinensis) has a large body of research supporting its various health effects. These effects relate to the presence of a number of different phytochemicals within tea including flavonoids, the amino acid L-theanine and a number of methylxanthines including caffeine and theophylline. One aspect of tea that is reasonably well reported is that of its claiming effect. In this regard, studies have investigated the effects of tea drinking on a number of mental functions, including mental health and mental stress levels. For example, in one study, tea drinking was associated with reduced anxiety levels in University students. One explanation for this is the presence of the amino acid L-theanine, which may activate the NMDA receptor in the brain, blocking some of its effects and thus reducing the excitability of part of the brain associated with generating anxiety. Based on the overall benefits of drinking tea, and its safety, it is recommended that consuming tea as part of the diet may confer significant health advantages.
