High blood pressure is a condition that around 600 million people suffer from. If not treated, high blood pressure may lead to heart attacks, congestive heart failure, blood vessel damage, stroke , brain damage and other diseases and is considered to be one of the most common and deadly cardiovascular conditions.
Scientists did a trial to see how coffee influences blood pressure and found coffee not guilty in causing high blood pressure. However, sugared and diet colas like Pepsi and Coke are newly suspected. There still aren’t any biological cause and effect for the connection and more research will be done to prove these theories.
During a 12-year study, researchers were using statistical programs to look at the women’s consumption of regular colas, diet colas and regular and decaffeinated coffee and tea.
The results showed no causal relationship between coffee and high blood pressure. The findings for tea were less clear, showing mixed effects depending on the participant's age but there was a clear correlation between cola drinking and high blood pressure.
While one side welcomes the study and the research, there is another side that says that many other factors haven’t been taken into consideration like nutrition and beverages women with hypertension didn’t drink.
Authors themselves report that they have only found a connection between cola and high blood pressure. They also suggest possible avenues for exploration like the effect of caramel coloring in all colas and high-fructose corn syrup in sugared ones.
