From recharging our body and focus for the next day’s exam to soothing stress, coffee has been an integral part of everyone’s life. However, despite proving itself in terms of providing several health benefits some negative side effects have always been associated with excess coffee consumption.
Most recently, a study published in The American Journal of Clinical Nutrition concluded that six or more cups of coffee per day can increase the risk of heart disease by about 22 percent. Is that true though? An even newer study debunks this – it says that no matter how much coffee you consume in a day, it will not effect your heart health as coffee doesn’t stiffen arteries.
What Did This Study Reveal?
A latest study on coffee has something good to say about it – as per this new research you can drink up to 25 cups of coffee in a day and not experience any adverse effects on your cardiovascular health. This research was carried out by investigators at the William Harvey Research Institute at Queen Mary University, London.
There are several conflicting reports when it comes to the link between coffee consumption and heart health. However, this new research, unlike previous studies shows, a neutral relationship – it says that coffee consumption of an amount most would consider excess also doesn’t stiffen arteries, a side effect oft thought to come with too much caffeine intake.
Funded by the British Heart Foundation and presented on Monday at the British Cardiovascular Conference this study had more than 8000 participants. Among these, the average person in the high intake group was found to consume 5 cups of coffee every day while there were also people who drank 25 cups of it in a day. Factors such as blood pressure, weight, gender, ethnicity, etc. that could affect the association between heart health and cardiovascular risk were corrected.
Participants were made to go through MRI heart scans and infrared pulse wave tests, and it was found that people who were more likely to drink higher quantities of coffee were males, smokers and those who consumed alcohol regularly. After analyzing, it was found that coffee consumption even of the highest level did not cause arteries to stiffen.
Arteries are responsible for blood circulation and when they get stiffened more pressure is exerted on the heart which ups the risk of cardiovascular related health concerns such as stroke and heart attack. Researchers are looking to conduct more in-depth studies on people who consume 25 cups of coffee per day so as to set safe limits.
There’s a lot of conflicting research about coffee out there and it can be difficult to decide what to believe. While one study says that you shouldn’t drink more than six cups of coffee per day as that can up cardiovascular disease risk, another says that even 25 cups won’t stiffen arteries. At the end of the day, it is always best to practice caution and consume caffeine in moderation.
