Is Fructose (table sugar as well) poisonous?

Professor Robert Lustig has quite a few videos at Youtube (searchword Sugar, The Bitter Truth as an example) and he have published plentifull of information how poisonous frutcose is. Most interesting finding is a leptine resistense, which is a "Darvinian explanation" for the obesity. And fact that fructose causes fatty liver (metabolic disorder) as well. Take a look into his powepoint at http://www.slideshare.net/ancestralhealth/ahs-slidesrobert-lustig or article at The Atlantic http://www.theatlantic.com/health/archive/2012/02/the-most-unhappy-of-pleasures-this-is-your-brain-on-sugar/253341/ (for finnish speaking I have draft document here http://tinyurl.com/d69xwux) and if you think professor Lustig is right, how come food manufacturers keeps adding fructose almost into every food?

Therefore, it is not person's responsibility if brains tells you to eat more than you need (practically speaking your leptine does not work or your dopamine need elevating with sugar).

    In other hand, if sugar is not poisonous, then alcohol is not poisonous either. Both brokes liver cell mitochondrio, and causes fatty liver. What word should I use than "poison"?

    Krisztian: with your logic manufacturers should add cannabis to bread, just because people will want it. It most certainly makes life happier :)

    Once again, what is wrong with professor Lustig's statements? Why should I believe he is wrong? I see quite a few studies at Pubmed.com about fructose being not good. Are them "pseudoscientific" all? For example, related to Mediator drug (http://www.bbc.co.uk/news/world-europe-12155639), science proved Mediator is safe to use, but in practise it wasn't. Thinking whole process, I presume we still live in similar science atmosphere where Nicolaus Copernicus lived when he tried to bring up his idea about heliocentric model. Took some 400 years before other scientists believed "yes, he was right".

    Why we keep saying fats are reason for obesity, when reports shows that fat consumption has dropped more than 10% in past 25 years, but obesity (and related sicknesses like Alzaimer, diabetes II etc) has tripled in the same time?

    What I do not understand here?

      ugh, oh, wait. what? you say that we are not responsible for our actions, because our brain tell us to do things? what kind of denial of responsibility is that? can we also say that we cheat, steal or kill because of our brain told us so?

      certainly i'm in command of my hand. i either take that product fro the shelf or not. nobody else than me makes this decision, and i clearly can not take it. if i do, it is my choice, whatever influences were there.

          Apr 13 2012: Hey, he was about some kind of addiction, what is much more likely to be less controlling of yourself, plus, it is not a crime, plus, sugar in most attractive forms is all around us and it is a hard mission for many people not to overdose it in their simple daily meals.

          Apr 13 2012: julija, a hard mission is exactly what it sounds: a hard mission. just as hard as for a poor person not to steal. or an angry person not to hit. maybe it is not fair to have hard tasks, but that's what we got. the last thing we need is to look for a scapegoat.

          Apr 13 2012: I meant that an absolutely average person who does not care of something like amount of sugar, who does not have overweight problems yet, who finds more interesting businesses than studying 'the eating' overdoses it.
          The main point here is that it may cause an addiction. Then, the idea of simple controlling of yourself does not work.

          Apr 13 2012: absolutely average person hears every day about how important healthy diet is. not caring is not an excuse. if you don't care about a danger, you are in trouble.
