Tea Consumption and Human Health: A Review of Benefits and Impact on Chronic Disease Prevention

Abstract

Tea, derived from the Camellia sinensis plant, is a globally consumed beverage with a rich history spanning thousands of years. Its cultural and social significance is evident in numerous societies, from ancient China to modern Western cultures. Historically revered for its potential health benefits, tea has gained scientific support for its role in chronic disease prevention. This review examines the historical and cultural importance of tea, its bioactive compounds, and its impact on health. Key areas include cancer prevention, cardiovascular health, metabolic syndrome management, and neuroprotection. Green tea, particularly noted for its high concentration of catechins, has been extensively studied for its health-promoting effects, including antioxidant, anti-inflammatory, and cancer-preventive properties. Black, oolong, and white teas each offer distinct benefits due to their unique compositions. Despite the promising evidence, potential risks such as caffeine sensitivity and reduced iron absorption should be considered. Future research is needed to further elucidate the mechanisms underlying tea’s health benefits and to explore its efficacy across diverse populations.
