Here is Why I Drink Vast Quantities of Alcohol Instead of Coffee By James Reed

     Look, too much coffee is bad for you, that is why I drink alcohol, where the catastrophic health effects are well known. Coffee is seductive and supposedly has some health benefits, while alcohol does not lie to you, it is straight out poison, and I can respect that.

“Drinking too many cups of coffee can trigger diseases including osteoarthritis and obesity, a world-first study has found. Coffee is one of the most commonly consumed drinks in the world and has previously been linked to a healthy lifestyle but researchers from the University of South Australia say their study shows excess consumption can cause poor health. Using data from more than 300,000 participants in the UK Biobank, the research team examined connections between habitual coffee consumption and a range of diseases. Genetic epidemiologist Professor Elina Hypponen said understanding risks associated with coffee intake would have widespread implications for community health. In an earlier study, the research team found six cups a day was considered the upper limit of safe consumption. “Typically, the effects of coffee consumption are investigated using an observational approach, where comparisons are made against non-coffee-drinkers. But this can deliver misleading results,” Professor Hypponen said. “In this study, we used a genetic approach ... to establish the true effects of coffee consumption. Reassuringly, our results suggest that moderate coffee drinking is mostly safe.”

     I will drink to that!
