There are two things that one needs to know about this topic:
1. The need to proclaim "new" evidence from researchers in wanting to get published and getting government grant money despite the fact that this horse has been flogged to death several times.
2. The turf war and lawsuits between artificial and natural sweeteners that pre-dates my birth; with claims of health on both sides.
BTW, I drink Diet Pepsi.™
PS: Can anyone find research on how many deaths by Aspartame since the introduction of the product.
