May 14: Recent study published in American Journal of Clinical Nutrition reveals that drinking six more cups of coffee per day can be harmful and increase risk of heart ailments up to 22 per cent.
According to the World Health Organization cardiovascular disease is the leading cause of death yet one of the most easily preventable.
Dr Ang Zhou and Elina Hypponen of the Australian Centre for Precision Health, in their study of association between long-term coffee consumption and cardiovascular disease, confirm that caffeine causes high blood pressure and is a precursor to heart disease.
Caffeine, although a stimulant and energiser consumed commonly, was never placed within a certain limit, especially in terms of consumption and cardiovascular health. Hypponen adds that the jittery, irritable and nauseating feeling some experience after consuming caffeine suggests that one has reached their limit for the time being.
Excessive caffeine consumption is a cause of high blood pressure which consequently leads to cardiovascular diseases. According to Hypponen the data from their research reveals that more than six cups of caffeine a day can start to negatively affect one’s heart and blood pressure.
The study has also explored the relationship between coffee consumption and genetic factors involved in increased risk of cardiovascular disease. The ability of caffeine-metabolizing gene(CYP1A2) to process caffeine better was studied among 347,077 participants aged 37-73, using UK Bio-bank data.
Although the carriers of this fast processing gene variation metabolizes coffee four times quicker, Hypponen says that these people cannot consume more caffeine without adversely affecting their health. Caffeine, as with many other things should be consumed in moderation as overindulgence will surely lead to health risks, she adds.
