All my life I've loved Coke. The regular stuff, or "full fat" as a friend of mine would call it. As I rumble though my 20's, though, I've noticed that a can of Coke really does feel like it has as much sugar in as it says. Sometimes I can't even finish a can, it just gets too sickly, and then an hour or so later I might get a headache or become tired. Recently I've started drinking Diet Pepsi and, well, it's very nice. Very fizzy, as Pepsi is, but light and a can goes down easily. Now it says on the can that it contains 0% of an adults RDA of sugar, and about 1 calorie. It still contains caffeine, hurrah, but I'm guessing it must also contain an absolute stack of sweeteners? Now I've read stuff about sweeteners before but I was wondering what the MR communities thoughts on them was. Is it better to drink "full fat" drinks containing natural sugars (I don't think we use that manufactured glucose-fructose syrup stuff in the UK/Europe that you guys in the US have used/still use) as part of an otherwise healthy and active lifestyle, or are sweeteners better for (and safe for) the body in the long term? And what's your preference? Naturally sweet, or artificial?
