I agree. There are two sides to everything.
I started reading case studies (because I have nothing better to do here at work

) and found a lot of loop holes. I assumed that these case studies were unbiased btw. Many of them concluded that aspartame did have negative effects, on rats. But none could be found on actual humans.
I also found a few personal testimonies where the person stated that reducing aspartame made their headache go away. True or not, it's inconclusive. The major argument was that aspartame is a government conspiracy used for god knows what lol. I’m not getting into that one.
The other side's argument was that this stuff has been around since 1965. It was initially banned by the FDA and brought back by Rumsfeld 7 yrs later IIRC. So that’s quit a long time and I don’t see people dropping like flies here. There is also no conclusive evidence stating the effects on humans that I could find. There were only speculations, or correlations.
From what I gathered, large doses are harmful but the average daily intake is well within the FDA's recommended guidelines.
