Is Drinking Tea Beneficial for Health?

Dr. Khalid is a health researcher and science writer with a Ph.D. in clinical research.


A recently published research article in Science News correlates the high consumption of tea with memory enhancement. The article claims the high potential of tea to improve the functionality of the brain network and the utilization of its significant resources. However, the article does not delineate the mechanisms adopted by the tea ingredients to extend a protective effect on brain physiology. Interestingly, a range of clinical studies continues to highlight the toxicological effects of pyrrolizidine alkaloids that are regarded as the essential components of herbal teas. The toxic and cancerous effects of these alkaloids are not hidden from the scientific community. The hefty consumption of pyrrolizidine alkaloids with herbal infusions increases the risk of genetic mutations that spontaneously trigger various cancer-causing mechanisms and disease processes inside the human body. The side effects of green tea extracts are also widely published in the medical literature. Physicians recommend a limited consumption of green tea to pregnant and breastfeeding women based on the risk of toxic effects and clinical complications; however, scientific studies so far have not produced conclusive evidence regarding the adverse impact of green tea on pregnant women. Accordingly, strong advocacy for the health benefits of high tea consumption is not ethically justified and could lead to several misconceptions regarding its medicinal uses.

High tea consumption for the sake of health benefits appears to be the greatest fallacy that requires unnegotiable rejection by the medical community. Tea addiction is a burning topic that requires open debates between health care professionals and the public to uncover its bitter reality. Tea promotion by big media houses in coordination with top-notch entrepreneurship appears to be a strong business strategy that rarely benefits the health and wellness of tea consumers. Some of the commonly reported problems with high consumption of tea include gastric trouble, high blood pressure, weight gain, diabetes, coagulation disorders, and heart disease. The media outlets must introspect their business campaigns regarding tea promotion and support research activities to emphasize health adversities associated with the high consumption of tea in healthy populations. Finally, public advocacy of high tea consumption lacks substance until evidenced by concrete research findings.
