Daily tea consumption may boost chronic kidney disease treatment, improve survival, and promote a healthier life, especially in the early stages.
Chronic kidney disease (CKD) patients may have a new ally in their fight for longevity—tea.
A revolutionary study has revealed drinking tea regularly can significantly reduce the risk of death for those living with CKD, especially in the early stages of the disease—raising the question: How much tea is enough and does the type matter?
For years, tea has been touted for its general health benefits. However, its specific influence on CKD patients, especially regarding life expectancy, was largely unexplored—until now. This research by Jin Li et al., based on the National Health and Nutrition Examination Survey,
underlined tea consumption’s protective effects on mortality risk.
How the Study Worked: A Closer Look at the Data
The study analyzed 17,575 CKD patients from a pool of over 45,000 participants, carefully excluding individuals with extreme dietary habits, pregnancy, or conditions unrelated to CKD. The results, based on data collected from 1999 to 2018, revealed a powerful connection between tea consumption and reduced mortality rates. The participants’ average age was 62.3 years, with just over half being female and a large portion (57.3%) identifying as non-Hispanic White.
Key Findings of the Study
For CKD patients, particularly those in stages 1 and 2, drinking up to 4 cups of tea per day was linked to a noteworthy reduction in all-cause mortality. Specifically, the risk of death was reduced by 11% in those who drank tea compared to those who didn’t.
Interestingly, sipping oxidized tea (such as black tea) delivered even more noteworthy benefits—just one additional cup a day lessened all-cause mortality risk by 10%. The study also found that replacing one cup of green tea with one cup of oxidized tea each day led to an 8% reduction in all-cause mortality and an 11% decline in cardiovascular-related deaths.
This study offers a glimmer of hope for CKD patients looking for natural ways to improve their health outcomes.
