An excess of fructose is an express road to the creation of fat. And compared to sucrose it’s not as satisfying in a beverage and leads to more after-cravings.

Do you know how lactose measures up?

[HiTech RedNeck]

Lactose can’t be absorbed in the human digestive tract directly, but in the lactase enzyme converted form it doesn’t have the molecular backbone for triglycerides that fructose has. Lactose wouldn’t be useful to sweeten anything, though, and an excess can bring on bloating and loose bowels.
