Don't eat butter, wait it is OK to eat butter.
Don't eat salt, wait it is OK to eat butter.
Now, don't drink coffee, wait it is OK to drink coffee.
Your regular cup of joe in the morning might provide an extra jolt to your day, but it luckily won’t do the same to your heart, according to new research published Tuesday in the Journal of the American Heart Association.
The University of California, San Francisco (UCSF) researchers pored through data taken from theCardiovascular Health Study (CHS), one of the largest nationally funded observational studies of risk factors for cardiovascular disease in adults 65 years or older. Randomly selecting 1,388 participants (out of around 6,000 in total), the researchers then attempted to find the relationship, if any, between their regular consumption of caffeinated products such as coffee and the likelihood they experienced either premature atrial contractions (PACs) and premature ventricular contractions (PVCs), ultimately concluding none existed.
Though PACs and PVCs, commonly known as early or extra heartbeats, happen fairly often for no apparent reason and are generally harmless, there is recent evidence showing persistent extra heartbeats can be an indication of worsening circulation woes in the heartand brain. On the flip side, according to the authors, the perception that caffeine consumption can cause an increase of PACs and PVCs was based mostly on old studies that didn’t directly examine that relationship. It’s a perception that’s led organizations as venerated as the American Heart Association to precautiously warn against caffeine for people with a history of extra heartbeats.We blow billions of dollars on these studies about what "causes" heart disease and cancer, instead of trying to cure them.
