My anecdata is that at one point Aspartame and/or Asesulfame K did something to my gut flora. Now both or either one (can't say which) give me gas. And not funny gas but "this is a war crime" -gas. Sugary drinks don't do this. Also this is how I discovered that Scandinavian Pepsi started replacing sugar partially with Aspartame. Took me a while to read the label and find out. I switched from Pepsi to Coke (still full sugar) and the issues went away. Even though a substance is studied extensively, there might still be adverse effects that people don't attribute to it. I'm not afraid it would give me cancer but bioweapon levels of gas is something I can't live with. Sadly it's getting harder and harder to find drinks that don't have Aspartame in it...
