I don't usually worry about artificial sweeteners. But this article on acesulfame shows good reason to be concerned, if the claims are true: FDA and NIH Disappoint on Sweetener Safety.

When I say I don't usually worry about artificial sweeteners, I mean that drinking 2 liters of soft drink per day is when I should start to worry about aspartame, based on what I've read. Apply a good safe engineering fudge factor and say half a liter - so personally, I'd avoid drinking more than half a liter per day. Not an issue - that's more than I drink in most months.

More to the point, the "foods" mentioned as containing this additive are junk foods. So while I'm behind the scientist-blogger raising these concerns, I will stick to eating actual food. Speaking of which, there's some sweet pineapple and passionfruit waiting for me (Guatemala is great for fruit n veg!)
