Aught3 said:What's HCFS, high corn fructose syrup?
Anyway, thanks for the link Scaly fascinating research - I note that their explanations of the effect don't make a lot of sense and am wondering what the real answer is.
Disclaimer: I do not make typos, I make intentional misspellings in order to test the perceptiveness of others. Yeah. that's it.
The video is a pretty good explanation of the biology at hand, I didn't realize it was so pronounced though.
IIRC that video explains how HFCS and sucrose have essentially the same effect on the human body. HFCS has slightly more fructose but the researchers seem to discount that as a sufficient explanation for their results. They then go on to talk about how slower adsorption or the sucrase enzyme might explain the results, but the sucrase enzyme is extremely efficient so I doubt this can be a sufficient explanation either.
I'd have to read the full study to find out exactly how they came to that conclusion though.
Found the study but it's not open access. http://www.ncbi.nlm.nih.gov/pubmed/20219526

I'm pretty sure the video is about how fructose is bad, that high fructose corn syrup is composed of about 55% fructose, and that sugar is composed of 50% fructose so that they're both roughly just as bad for you. But it is about how fructose is processed by your body differently than glucose and how that directly leads to weight problems and lower quality of life (in excess, except that we all eat so much sugar that basically all of us consume it in excess).
So... Aught3's right about this one I think.

It's not much of a shortcut the bond is broken fairly quickly on the magnitude of seconds or minutes. Our bodies are designed to get sugar molecules from our GI tract and into ours cells quickly. If you heat the sugar before eating it also breaks the chemical bond.scalyblue said:The problem with HCFS isn't the fructose content so much as the fructose isn't chemically bound to anything like it is in cane sugar, giving it a shortcut to metabolize.
Also the more common type of HFCS is actually on 42% fructose, the HFCS55 is mainly used in soft drinks.

Which is why (as you pointed out) this research is new and interesting, and does contradict things he said in that video. I posted it because (1) I didn't read the article very well and (2) it's still worth watching anyway because we all know sugar is bad for you we just never realize how bad.Aught3 said:It's not much of a shortcut the bond is broken fairly quickly on the magnitude of seconds or minutes.
