I bought a yogurt that claimed “crytalline fructose is a naturally low glycemic sweetener.” Metabolizes slower than sugar–so better for you. I’m glad I’m not diabetic.

Allen,
Check out this website and go about a quarter of the way down the page to the section “Fructose Metabolism”:
http://www.nutritionandmetabolism.com/content/2/1/5
You’ll find that fructose is just a sugar and it is metabolized just as readily and just as fast as sucrose, ordinary sugar.
The body metabolizes it in a slightly different way, using a different enzyme to break it down, but the end result is just the same as it is with sucrose.
To our bodies, a sugar is a sugar. The only exception to this are the “sugar alcohols” like xylitol or sorbitol, which, though naturally-occurring (and in fact we create xylitol in our carbohydrate metabolism), are different kinds of sugars, five-carbon instead of 6, and are absorbed much more slowly than are the other, more well-known sugars. They are sugars, and therefore they do have calories, but not as many as the other sugars because we eliminate them before they are completely absorbed.
But fructose? Yup–it’s a sugar like the stuff on our tables.
