Fructose is really bad

It not only completely fails to trigger your body's awareness that you have eaten enough, but it actively inhibits it, making your brain think you're starving. Which has caused us a lot of problems, because it's in everything.

It's similarly bad in High Fructose Corn Syrup and sucrose (labeled "sugar", cane sugar, "real sugar"), but glucose is fine because the feedback loop works fine. Lactose is fine.

Has a great graph showing what happens when, primarily, he gets obese kids to stop drinking anything but water and milk (instead of soda and juice). They stop being obese.

Got the video from a blog on the subject.

I've been consuming lots of HFCS again lately. Tonight my dinner was a whole avocado (man that was decadent), sweet potato (with butter), and chicken breast (with salt). With lots of leftovers for tomorrow.

The video I linked to seemed to provide plenty of good evidence that getting your calories from fructose, including via HFCS or sucrose, is really bad. And that number of calories consumed alone really isn't the problem.

If it is saying that lots of calories from sucrose (cane sugar) and HFCS are both bad that is good information. Though is is claiming high calories from glucose and lactose are just great I'm a tad skeptical.

Try watching it? He goes into the details of how and where which molecules are converted to what. He's claiming that the problem with fructose / sucrose / HFCS is that not only do we lack the relevant receptor to recognize it as sustenance, it actually blocks other things from being recognized as sustenance, so we don't stop consuming calories when we should. I don't remember the details, I should watch it again and take notes.

He says the byproducts of fructose in the liver (free fatty acids and JNK1) cause insulin resistance, so leptin doesn't get produced, so your brain not only doesn't realize you consumed the calories of fructose, but also is less aware of other stuff you eat.

Just watched an 11 minute summary of the other video: http://www.youtube.com/watch?v=tdMjKEncojQ
