When I became diabetic, I did research on it. Real research, not just the internet fringe sites. Everything I found said that aspartame is only dangerous in ridiculously high volumes. Like, 15-20 cans of diet coke per day, every day, for 20 years. And even then, your chances of developing cancer are only slightly higher. The lab rats developed cancer because they were fed the equivalent of those amounts. In normal volume of about 3-4, it's harmless.
