I started wondering about this issue a few days ago, so I did some digging and I found out something very interesting about sucrose and fructose. First, the big one: we eat a lot of fructose nowadays, in the form of high-fructose corn syrup, which in addition to doubling our intake of sugar since the 1960's, also interferes with the growth and maintenance of all different types of connective tissues. How? Apparently the metabolism of fructose requires the diversion of copper away from the production of Lysl oxidase, which is a key enzyme used in the production of collagen and elastin. Furthermore, sucrose (plain table sugar) is a di-saccharide sugar composed of a glucose molecule and a fructose molecule joined end-to-end (or something like that), which means that even using plain white sugar puts more fructose into your body. Damn. To make matters worse, fructose comes from sweet fruits; yeah, the one healthy snack that also tastes good can actually weaken your connective tissue. Fantastic. On the other hand, glucose is the sugar that the human body uses directly, without having to be metabolised into any other intermediate sugars -- it goes straight into your cells and gets turned into ATP from there, so since it doesn't have to be metabolised, it doesn't pull vitamins and minerals away from other important bodily functions. Problem is, it's harder than hell to buy glucose in any meaningful quantities, though some diabetic shops sell glucose syrup in bottles. (Being a mono-saccharide sugar, it apparently causes fewer problems for diabetics despite being absorbed very quickly.) However, it doesn't taste very sweet compared to di-saccharide sugars, so you could end up using a lot of it, which would be counter-productive. So, unless you want to run out to the health-food store and stock up on bottles of glucose syrup like you're expecting a nuclear war, the only option left is dextrose. (There's also maltose, but I haven't gotten enough info on that one yet.) I've seen it recommended here before, and now I know why it's recommended; it's a mono-saccharide sugar, so it's easily absorbed yet less likely to induce an insulin crash, it's roughly as sweet as table sugar, it doesn't contain any hidden fructose (because it's not a complex sugar), and you can buy it in a 5lb bag just like sucrose. Good deal. - - - Just thought I'd share what I found out. If anyone has anything else to add, go right ahead.
