The researchers were trying to find out the connection between obesity, fatty liver, and insulin resistance.
We already knew that when we consume added sweeteners, such as high fructose corn syrup and table sugar (sucrose), we receive all the benefits of eating that carbage: A liver that becomes too fatty to do its job. It develops scar tissue from all the fatty deposits, which causes cirrhosis, and the liver looks like it's been on a 25-year alcoholic bender. Also, the cells in the body rebel, and refuse to absorb all that extra sugar (glucose) floating around in our blood. (Can you say "diabetes," boys and girls?)
But wait! There's more!
Those pesky researchers have reported that fatty liver and insulin resistance may also result from fructose produced in the liver from non-fructose containing carbohydrates.
Say what? The liver produces its own fructose? From consumed carbohydrate?
But...but...we are bombarded every day with how, according to the USDA food pyramid, we are supposed to eat 11 servings of "heart-healthy whole-grain high-fiber carbohydrate foods" every day! Carbohydrate is necessary for energy! For good health! For... well...the development of obesity and insulin resistance!
A direct quote from said researchers: "Our data suggests that it is the fructose generated from glucose that is largely responsible for how carbohydrates cause fatty liver and insulin resistance."
Let's try another: "Ironically, our study shows that much of the risk from ingesting high glycemic foods is actually due to the generation of fructose... These studies challenge the dogma that fructose is safe and that it is simply the high glycemic carbohydrates that need to be restricted."
Take that, you "new-Atkins" sell-outs.
It doesn't matter if that slice of bread is whole-wheat, or that cracker is gluten-free rice, or you are glomming down steel-cut oatmeal for breakfast. Your body is going to take that carb, convert it to fructose, and wreak havoc on your metabolic health.
