Wine drinkers suffering whiplash from the good news/bad news/good news/bad news cycle of studies that link wine to cancer (and heart disease and diabetes, etc.) just got the latest bit of bad news last week, when the American Journal of Epidemiology released a study last week that linked alcohol consumption to four different types of cancer.

The study measured daily consumption and found that anyone who exceeded moderate consumption (defined as one drink per day) were at a much greater risk for developing cancer.

But the authors of the study failed to take into account the type of alcohol that was consumed – beer, wine or liquor –  not to mention other lifestyle choices of the study participants. Did they eat fried food? Where did they live and what did they do for a living? All of this could be considered relevant.
