By their own admission in that article, it says "Studies have shown that the human body metabolizes fructose, the sweetest of the natural sugars, in a way that may promote weight gain. Specifically, fructose does not promote the production of certain hormones that help regulate appetite and fat storage, and it promotes elevated levels of tricglycerides that researchers have linked to an increased risk of heart disease."
I agree it's similar to sugar in most ways, but different. The other thing was the cheapness of it, and the surge in soft drink sizes and consumption, leading to excess calories. I notice also, that things that didn't even have sugar in them when we were younger, now have HFCS in them. So it's probably a mixture of the above with the 'hidden calorie' factor that's getting people. That was interesting about corn not having any fructose in it; they alter the carbs to become fructose chemically. Hm.
I'll just play safe and avoid sugars at large, except for PWO shakes, with maltodextrin and dextrose...maybe a little fruit. I looked into using fruit, and the amount of fructose in fruit is so low, that it does no harm. Leave it to God to make food healthy for you, heheh.
Oh, and I've been in the sweetener wars a bit...I finally decided on "Sugar Twin" as the winner, being made of dextrose and maltodextrin, our favorite ingredients.
