Aspartame? There is one brand of milk that is sold locally that causes my daughter to break out in hives every time that she drinks it.
Second, it is a moot point since aspartame has been found harmless after thorough and exhaustive study by actual scientists as opposed to conspiracy minded bloggers. The hoax that it is toxic came originally from a crazy chain email way back in the day.
You are entitled to your opinion, no matter how ignorant it is, but you are not entitled to spread BS and expect to get away with it.
