Association and causality are pretty far apart from one another, so that's what I was really curious about.
The number of claims about artificial sweeteners over the years (ZOMG CANCER!) based on wild speculation or misunderstandings has led me to err on the side of caution when new claims come up. Then again, I drink a lot of coke zero, so it's possible the mind control drugs they lace it with are simply having their intended effect.
