On nutrition labels, sugar is just sugar. But when it comes to how the body metabolizes that sugar, there are two very different molecules that make up what we think of as table sugar. There's glucose, the more easily metabolized of the two that provides most of the body’s energy, and fructose, which can only be processed in the liver and is associated with Type 2 diabetes and obesity. But that's not to say you should swear off sugar entirely. Naturally occurring fructose in fruit is fine -- it's the large amount that's problematic. And according to a new study published in the journal Nutrition, we may be consuming more fructose than we bargained for when we drink sweetened beverages.
