New hypothesis of British scientists
The news around any kind of coffee and the volume of its consumption is always contradictory. And amid claims that caffeine is a dangerous and no-nonsense story, a new study from the UK Heart Foundation seems irresponsible to say the least. Scientists at the medical center have studied the relationship between coffee consumption and arterial stiffness. And, according to their observations, the consumption is up to 25% (no, we have not sealed ourselves!) Cups of coffee per day does not increase the likelihood of a heart attack or stroke.
Of course, coffee lovers are pleased to hear that their habit is supposedly heart-safe. But does this mean that everyone should increase their intake by more than 20 cups? Not certainly in that way.
“It’s pretty silly reporting in my opinion,” says Dr. David Katz, director of the Yale Griffin Prevention Research Center and author of The Truth About Food, in an interview on the topic with the Huffington Post.
Katz’s comment is, of course, logical if only because if a product is considered safe for a very specific reason, that does not make it safe in general. For example, a number of solid studies suggest that coffee and caffeine have a potentially negative impact on all body systems. In other words, the more you consume, the more vulnerable your body becomes.
“There are many more reasons to be concerned about the myriad other effects associated with a dose of caffeine, from increased blood pressure to faster heart rate,” Katz notes. More importantly, extreme coffee consumption is likely to be associated with harm not related to the heart (or at least not directly related), such as insomnia and a range of metabolic effects ranging from microbiome disruption to bone density.
Caffeine is the most used stimulant in the world and is generally safe at a daily dose of 400 milligrams (3-4 cups or less), according to a report by the American Psychological Association. Research shows that people with anxiety disorders may be sensitive to coffee. Especially those who are prone to panic attacks. Caffeine can also trigger a stress hormone.
Conclusions: The 25 Cups of Coffee a Day study simply shows the absence of one very specific harm to the body. And yet it is worth limiting yourself to one or three “dosages”.
