Scientists say: How many cups of tea, coffee, and green tea should you drink?
Scientists say: How many cups of tea, coffee, and green tea should you drink?

The daily consumption of a cup of tea or coffee has recently been proven to potentially strengthen the body in old age, according to a recent research study. Researchers suggest that individuals who consume coffee and tea during their middle age (between 40 and 60 years) may have a reduced likelihood of physical weakness in their later years, with the primary reason being the presence of caffeine in tea and coffee. Those who consumed four cups of coffee a day experienced the most significant benefits, while individuals who drank black or green tea also observed positive results.

The study, conducted by a team from the National University of Singapore, involved a 20-year follow-up of 12,000 individuals aged between 45 and 74 years. Professor Koh Woon Puay, from the Yong Loo Lin School of Medicine's Healthy Longevity Translational Research Program, stated, "Coffee and tea are primary beverage choices in many regions, including Singapore and various parts of the world. Our research indicates that consuming these beverages during midlife may potentially reduce the likelihood of physical weakness in the later years of life."

Professor Koh Woon Puay further added, "However, further research is necessary to validate these findings and to investigate whether the impact on physical weakness is attributed to caffeine or other chemical compounds." The study involved interviews with individuals of an average age of 53, inquiring about their habits of consuming caffeine-containing drinks such as coffee, tea, cold beverages, and items like chocolate. The participants, whose average age was 73, were also asked about their weight and energy levels, and they underwent handgrip power and Timed Up and Go (TUG) tests to assess their strength.

Among the 12,000 participants, it was found that more than three-quarters (68.5%) consumed coffee daily. Within this group, 52.9% consumed one cup of coffee per day, 42.2% consumed two to three cups daily, and the remaining individuals consumed four or more cups per day. Tea drinkers were categorized based on their tea consumption habits, including those who never drank tea, those who consumed tea at least once a month, those who consumed tea at least once a week, and those who consumed tea daily.

The results of the research indicated that consuming coffee, black tea, or green tea during middle age was associated with a reduced likelihood of physical weakness in the later years compared to those who consumed four or more cups of coffee daily. Individuals who consumed black or green tea daily also exhibited a significantly lower likelihood of physical weakness compared to those who did not drink tea.

A study published in the Journal of the American Medical Directors Association concluded that, even without the consideration of the source of caffeine, higher caffeine consumption was associated with a decreased likelihood of physical weakness. Researchers emphasized the need for further investigations to confirm the conclusions and to explore the potential effects of caffeine and other chemical compounds on physical weakness. The findings of this research hold promising implications for the potential benefits of regular coffee and tea consumption in promoting physical well-being, particularly in older age. Such insights provide valuable information for individuals looking to maintain their health and vitality throughout their lifespan.
