New research published in the American Journal of Clinical Nutrition found that two important indicators of cardio health – blood pressure and heart rate – can influence how much coffee people consume.
The study compared health reports and coffee consumption data of over 390,000 adults. The results showed that individuals with higher blood pressure are inclined to drink less coffee than those with regular blood pressure levels. Furthermore, those with angina or arrhythmia were also likely to drink less coffee or no coffee whatsoever.
The research also found that a genetic mechanism can protect people with cardio conditions from caffeine consumption. “People drink coffee for all sorts of reasons — to pick them up when they’re feeling tired, because it tastes good, or simply because it’s part of their daily routine,” said Elina Hyppönen, the lead author of the research. “But what we don’t recognize is that people subconsciously self-regulate safe levels of caffeine based on how high their blood pressure is, and this is likely a result of a protective genetic mechanism.”
Moreover, the authors of the study recommended that people should listen to their body’s response concerning caffeine consumption. Genetics will guide the body’s decisions and reactions in order to protect our overall cardio health. Previous research also found that coffee was linked to a lower risk of heart failure. In fact, the findings showed that drinking one or more cups of coffee per day can significantly decrease heart failure. The meta-analysis published in the American Heart Association found a decrease in the risk of heart failure by 5-12%. The study analyzed over 21,000 adults. However, individuals witnessed a positive effect only with caffeinated coffee.
The bottom line: enjoy caffeinated coffee in moderation and as part of an overall healthy diet.
