In the first study, researchers found that those who drank one can of cola increased their risk for blood pressure by nine percent and by 13 percent in the second study. Researchers also found that women consummating more than three cans of cola a day have an even higher risk of getting high blood pressure.
Though, the two studies show that there was a strong connection between caffeinated cola consumption and high blood pressure, the result did not completely established that cola drinks cause high blood pressure. Even if the study was done just by comparing two women who were matched for age, weight, physical activity, those who took alcohol, and smoke, researchers were in agreement that cola drinking remained a major risk factor.
Researchers concluded that some ingredients in cola drinks like caramel coloring in diet colas and the corn syrup in sugared colas — might be the culprits that cause high blood pressure. Further studies are ongoing to find out and identify what is really the link between these cola ingredients and high blood pressure.
Also, the study revealed that women who are regular or heavy coffee drinkers do not risk developing high blood pressure.
