No, not fructose, Glucose is the most basic sugar used by the body, fructose and sucrose(normal sugar) are a combination of two or more variations of glucose, and the body has to spend a little energy in order to break the bond holding the two glucose molecules together. A glucose only sweetener is slightly more efficient than any other.
Hmmm, Muscle Milk, there a growth story in there somewhere...?
About fructose:
Fructose is a hexose monosaccharide, meaning that it has only one carbon ring containing six carbon atoms. Monosaccharides include the simplest naturally-produced sugars, and includes glucose (hexose) and galactose. To say that fructose is more complex than glucose is misleading; they have the same chemical formula (C
6H
12O
6), just different molecular structures. Now, fructose requires a glucose rider to be effectively absorbed, which would make it an ideal low-sugar sweetener as long as it isn't paired with glucose, but other than that, a good idea would just be to eat 3 servings of fruit for something sweet. As always, everything in moderation.
