The risks and health benefits of coffee consumption have been see-sawing back and forth for centuries, from the 1600s where coffee was believed to cure coughs and headaches to a few decades later where it was claimed coffee made men impotent…
Recently, medical professionals feared that coffee could cause heart palpitations (meaning more noticeable heartbeats), however, a new study has put that fear to rest and concluded a number of benefits to drinking coffee! I always knew I was doing something right…
A study published in JAMA Internal Medicine has found that rather than causing cardiac arrhythmia (heart palpitations), the habitual drinking of coffee actually resulted in the lowering of the risk of developing an arrythmia. As explained by Dr. Gregory Marcus, corresponding author and arrythmia specialist, “each additional cup of habitual coffee consumed was associated with a 3% lower risk of incident arrhythmia“.
A separate study was conducted by Dr. Oliver Kennedy, member of the medical faculty of the University of Southampton in the UK. This study, published in the journal BMC Public Health, found that coffee had a wide range of benefits when it came to the development of liver disease. He concluded that coffee drinkers were:
21% less likely to develop chronic liver disease
20% less likely to develop chronic or fatty liver disease
49% less likely to die from chronic liver disease
The study indicates that three to four cups of either caffeinated or decaffeinated coffee daily can greatly reduce the risk of Chronic Liver Disease. The most beneficial form of coffee was found to be ground coffee, including decaf, however, instant coffee drinkers also gained some benefits. The findings were a result of examining almost 500,000 participants of the UK biobank for almost 12 years.
As Kennedy stated, “Coffee is widely accessible, and the benefits we see from our study may mean it could offer a potential preventative treatment for chronic liver disease… This would be especially valuable in countries with lower income and worse access to healthcare and where the burden of chronic liver disease is highest”
Other studies have indicated that coffee can lower the risk of Alzheimer’s, prostate and skin cancers, multiple sclerosis, Parkinson’s disease, and type 2 diabetes, just to name a few. However, these benefits are most active when drinking black coffee, since typical additives such as sugar and dairy products have their own health risks.
Of course, these benefits are exclusive for adults. As stated by the American Academy of Pediatrics, children and adolescents should not consume any beverages with any amount of caffeine, which includes colas, energy drinks, and coffees.
