So I thought I would give a listen to some of rxmuscle.com's other podcasts, so I downloaded the 9/16/13 episode of Heavy Muscle with Dave Palumbo and Chris Aceto..Around the 54 min mark, Dave starts talking about fructose and how bad it is, yadda yadda. And then says that there is "new research" showing that when you ingest simple carbs, high glycemic stuff, that inside the body, it gets converted to fructose. And he, of course, uses this as justification for consuming only low glycemic carbs like oats.But.. I've done a minimal amount of googling and can't find anything about studies showing even the possibility of glucose being converted to fructose once inside the body. And logically, I can't really see why the body would even do that, since it isn't a usable/storeable substrate.. Anyone seen anything on this?

Sounds like BS. Why would your body convert a simple sugar like glucose? It would either be stored as glycogen or if stores are full it would be stored as adipose through de novo lipogenisis.
This would require your body changing the physical structure of the a monosaccharide. Which it cannot do. It can break it down.. (i.e ATP) but it can't make a 5 sided monosaccharide into a 6 sided or vise versa. There's no function that can/would do that in the human body. It would be a complete waste of energy.
He probably is referring to sucrose. Most people to sugar as simple carbs. Sugar usually means sucrose. Sounds like he just doesn't know what the hell he is talking about.As breenhouse said, the body can not inter convert monosaccharides.

+1 but i think thats what I said ::) He may be referring to Sucrose, but even so when the body breaks it down it creates Glucose and Fructose.

Exactly. That's what I meant. The body does break down sucrose to glucose and fructose. But it doesn't convert glucose to fructose.
Don't remember specifically. But I know he definitely said that "new research" is showing that "in the body," high-GI carbs are being converted to fructose. And then went on to say that this is a great reason you should stick to the lower-GI carbs.. Definitely could have been referring to sucrose. In which case, that isn't "new research," ha.. I'm gonna take a relisten to that segment.
Timestamp-52:53DP: "New research has come out that links obesity, Chris, to the body's production of fructose."[...synopsis of what fructose is and that we all know about it because of Dr. Scott Connelly's work (never heard of him)...]DP: "Well, new research has been shown, now, that the ingestion of carbs, simple carbs, more high-glycemic carbs, which have a large spike in glucose.

And with that, they're saying this conversion to fructose is what's causing all the problems with obesity, and fatty liver, and insulin resistance. So, you know, if you're worried about heart disease, you're worried about these things like insulin resistance and type-2 diabetes, you might wanna limit your ingestion of high-glycemic carbs. [...] Like I said, you're better off eating the lower-glycemic carbs like brown rice, and sweet potatoes, and oatmeal; something that just takes a little longer to digest, because you get less of a spike of insulin, err of glucose and of insulin, and less of a conversion to fructose. So, I thought it was a pretty interesting study that that is the case."Then he says something to Chris about it's weird because you'd think when you convert to fructose, the body would produce less insulin because fructose is a low-glycemic carb.Ugh.Obviously these guys are good at what they do.. Palumbo is a big man, and Aceto has been training Cutler for Olympia and he's expected, apparently, to give Heath a great run for his money.. But seriously, this sort of shit is just boggling. And he never mentions what the actual study is, and there are no show notes or anything.

I would need to read the study he is referring to. I still don't know quite what is being referred to.

My thoughts as well. I was hoping there were show notes for the episode or something that might've linked to the study, but no luck. I have a feeling it's just him misinterpreting something he read.
