Are sweeteners dangerous? i read that aspartame, sucralose, acesulfame & neotame can cause some cancers. my wife is pregnant & i'm worried! thanks.

Stop worrying: Some of my teammates here will disagree, but I discount these fear claims. Just as every fruit and vegetable has somebody claiming it's a "superfood" that cures everything, so every artificial product has someone claiming it causes cancer, autism, mental illness and so forth. If these claims were true, the research piranhas at the NIH would have built reputations proving them.
