More Good News for Coffee Drinkers?
A large French retrospective analysis provides good news for caffeine lovers: investigators showed that drinking tea or coffee was associated with a small but statistically significant reduction in systolic and diastolic blood pressure. In addition, drinking tea and coffee was also associated with a significant reduction in pulse pressure and heart rate, although the heart-rate reductions were greater with tea.
Unfortunately, the researchers did not differentiate between green, black, or herbal tea consumption, which is one of the limitations of the analysis. In addition, the questionnaire is not sophisticated enough to address estimates in the caffeine content of the coffee consumed in France.
