(26,549 posts)And the fact that you know you are eating one or the other is why those feelings are meaningless.
Sucrose is broken into to a 50/50 blend before your body absorbs it. It happens in your duodenum, the beginning of your small intestine where most digestion happens.
Doesn't matter if you're Latin American or Nordic - that digestion happens in that place. Just like your lungs absorb oxygen whether you're Latin American or Nordic (Nordic selected for being on the opposite side of the planet).
Really, really wanting there to be a difference between HFCS metabolism and sucrose metabolism does not mean such a difference actually exists. Most people selling books (like the subject of this thread) exploit the fact that most people don't know HFCS and fructose are not the same thing, and so they only talk about fructose metabolism when that isn't what's actually going on.
