Good suggestion! It is safe and, in fact, Coca Cola ran a toxicology test less than a year ago and said there are no possible long-term side effects. Moreover, a study in 1974 fed rats 30,000x what a human would normally eat daily and found no side effects across multiple generations!!!

It is approved in Europe and Asia. In the US, however, due to dirty sabotage in the 70's by sugar and aspartame companies, the FDA decided to approve it as a food additive and not food. One company is working on that approval now though.
