While everyone knows HIV is bad, most people are aware that drinking lots of cola is probably not good for them. Unfortunately, an article in the July issue of the journal Epidemiology suggests that folks who drink more than two servings of cola per day (that's less than one of those 20-oz bottles!) had a higher risk of chronic kidney disease. The culprit seems to be cola's characteristic phosphoric acid, as other sodas and caffeinated drinks didn't show similar effects.
Finally, you probably thought that Selenium was good for you. Health food stores and "dietary supplement" companies have been touting it for years as a miracle for everything from cancer to obesity and beyond. Unfortunately, what looks like a pretty robust clinical trial has found that selenium supplementation appears to be linked to higher risk of diabetes. Granted, this result comes from secondary analysis, but still it should serve as a warning: we don't really know what all those "supplements" do to our bodies.
