‘Aspartame Causes Cancer’ Was a Classic Internet Hoax

Look, nobody’s telling you that you should drink diet beverages all the time. But when you do have a drink sweetened with aspartame, you don’t need to worry about getting cancer, multiple sclerosis or depression any more than you would with any other single substance you consume.
Aspartame was patented on this day in 1970 as Nutrasweet, one of the names it’s still sold under. Unlike that name suggests, it’s not particularly nutritious, but it’s not intrinsically bad for you like, say, smoking. Because of people’s concern around this substance, it’s been “one the most exhaustively studied substances in the human food supply,” according to the FDA. And it’s safe to consume, also according to our federal monitoring agency for foodstuffs.
