Hi. A few points. The amount of Aspartame in fizzy drinks is far higher than the amount in a tablet for sweetening tea or coffee. Can someone point me to scientific proof, not rumour, that aspartame actually has caused harm in humans as opposed to rats. There is no difference chemically between 'artificial' and 'natural' chemicals; a molecule is a molecule. Some natural foods are poisonous and many artificial ones aren't; it all depends on the specific chemicals present artificial or not and whether they are poisonous or not. So, as I posted earlier, I will continue having artificial sweeteners and avoid too much 'natural' sugar which is proven to be harmful due to it's ability to raise blood sugar levels and add to obesity
