Green tea to improve memory

Green tea has become a popular beverage worldwide because of its health benefits, including antioxidant, antimicrobial, and cholesterol-lowering effects.

Studies investigating the health benefits of caffeine-rich teas have found that higher consumption of green tea can reduce mortality risk, increase fat oxidation, promote energy expenditure, reduce blood pressure, and reduce the risk of diabetes, colorectal cancer, and gastric cancer development.

Various components present in green tea, including catechins, caffeine, theanine, and vitamins, are responsible for its health benefits. Among these components, theanine has been found to reduce brain atrophy, learning disabilities, stress, and depression. This amino acid has also been found to trigger a relaxation response.

In a new study, scientists have investigated the effect of green tea and roasted green tea consumption on human responses during a mental task.

The subjective assessments related to the task performance revealed a significantly higher average problem level in the green tea session than in the water session. However, in the roasted green tea session, significantly higher response rates and correct responses were observed than in the water session.

Overall, a significantly higher task performance was observed in the tea condition than in the water condition across all sessions. Between three mental task repetitions in the roasted green tea condition, the performance level was better in task 2 and task 3 compared to that in task 1.

Regarding fatigue level, a significant increase was observed after the task in all experimental conditions except in the second half session of the roasted green tea condition. However, no significant differences in the stress level were observed between sessions.
