WASHINGTON — A new study suggests that your morning brew might be doing more than just perking you up — it could be protecting you from a range of serious heart conditions. Researchers working with the Endocrine Society have found that drinking a moderate amount of coffee is associated with a lower risk of developing multiple cardiometabolic diseases. In simpler terms, your daily cup of coffee (or three) might help ward off conditions like Type 2 diabetes, heart disease, and stroke.
“Consuming three cups of coffee, or 200-300 mg caffeine, per day might help to reduce the risk of developing cardiometabolic multimorbidity in individuals without any cardiometabolic disease,” says Dr. Chaofu Ke, the lead author of the study from Suzhou Medical College in China, in a media release.
The issue is a lot of teetotalers don't drink anything because of their existing health conditions, really bad obesity, hypertension, liver problems, etc. So those that don't drink at all are actually less healthy than the average population, and those that drink in moderation are obviously healthier than those who drink a lot. So the results look like moderate drinking is the most healthy but there's an (or a lot of) omitted variable bias.
