ABSTRACT
Tea is one of the most widely consumed beverages globally and is recognized for its bioactive compounds, which have numerous positive effects on health. The bioactive compounds in tea, particularly polyphenols, antioxidants, and caffeine, make it valuable from a health perspective. The health benefits of tea primarily vary depending on the degree of fermentation: Green tea is made from unfermented tea leaves, while Oolong tea undergoes partial fermentation, and black tea is fully fermented. The polyphenols in tea, particularly catechins, have strong antioxidant properties and help prevent oxidative damage caused by free radicals, providing protective effects against various diseases. Additionally, the polyphenols in tea can accelerate metabolism, increase fat burning, and assist with weight management. The caffeine content in tea has a stimulating effect on the nervous system, improves cognitive functions, and alleviates fatigue. However, excessive caffeine intake can lead to sleep disturbances, anxiety, and heart rhythm issues, emphasizing the importance of moderation in tea consumption. Tea also provides benefits related to obesity and weight control. Particularly, green tea’s thermogenic effect boosts fat burning, supporting weight loss. Oolong tea, which has a high polyphenol content, improves fat metabolism and helps reduce obesity-related complications. Tea’s positive effects on gut microbiota are attributed to polyphenols, which promote the proliferation of beneficial bacteria while reducing the impact of harmful microorganisms. Black tea infusion powder helps increase the growth of probiotic bacteria, such as Bifidobacterium species, and reduces harmful compounds. Tea consumption has been found to benefit bone health, with daily tea intake reducing the risk of osteoporosis and increasing bone mineral density. While tea consumption offers many health benefits, determining the optimal dosage is crucial. In addition to the adverse effects of consuming excessively hot tea, overconsumption of certain tea components can have negative health impacts. It is emphasized that more clinical and epidemiological studies are needed to better understand the health effects of tea.
