A recent study published in The European Journal of Nutrition suggests that the way people consume tea and coffee can influence their risk of developing high blood pressure.
This study sheds light on the complex relationship between caffeine consumption and its impact on blood pressure.
Caffeine is a natural stimulant found in various beverages and products, including coffee, tea, cola, cocoa, guarana, and yerba mate.
It affects the central nervous system, heart, muscles, and blood pressure regulation. Caffeine stimulates brain activity and increases the release of hormones like cortisol and adrenaline.
Controversy has surrounded the connection between coffee and tea consumption and the risk of high blood pressure for some time. This study aimed to provide clarity on this issue by examining data from a large group of individuals.
The researchers analyzed data from 63,257 Chinese adults aged 45-74 living in Singapore. They collected information about participants’ coffee and tea consumption habits, among other lifestyle factors.
Over an average follow-up period of 9.5 years, the researchers identified 13,658 cases of high blood pressure among the study participants.
People who consumed three or more cups of coffee daily had a lower risk of developing high blood pressure compared to those who drank only one cup of coffee per day.
In contrast, daily consumers of black or green tea showed a slight increase in the risk of high blood pressure compared to those who consumed tea less frequently.
The study revealed a dose-response relationship between caffeine intake and high blood pressure risk. Those who consumed the highest caffeine levels (≥300 mg/day) had a 16% higher risk compared to those with the lowest caffeine intake (<50 mg/day).
The study suggests that drinking less than one cup of coffee per week or three or more cups per day may reduce the risk of high blood pressure. It is possible that compounds in coffee could counteract the effects of caffeine and benefit blood pressure. However, more research is needed to confirm this hypothesis.
This study highlights the influence of coffee and tea consumption on the risk of developing high blood pressure. It suggests that the way people consume these beverages can have a significant impact on their blood pressure.
Coffee drinkers who consume moderate to high amounts may experience a lower risk of high blood pressure, while daily tea drinkers and those with minimal coffee intake might face a slightly increased risk.
Further research is essential to explore the underlying mechanisms and confirm the potential benefits of coffee compounds on blood pressure regulation.
