I just watched this documentary and it is GREAT! Basically it starts as a followup to "Supersize Me" but its whole premise is the bullshit that dieticians and politics have been forcing down our throats for decades: That fat is bad for you, and sugar is good for you.
It's a funny documentary, and to prove a point the guy even did his own verison of the Supersize me diet - he ate nothing but fast food for 28 days, but kept the carbs under 100g per day, and going for a NEPA walk 6 days a week. He ended up losing about 12 pounds, even though he was taking in 50g of saturated fat each day. Obviously he's not saying that "fast food is good for you" but rather counter the point that "fat kills you"
Most people who read this site already know most of the information (many of the authors and scientists he talks to have been referenced and even interviewed here) but it's still worth watching due to the entertainment factor, and helps spread the knowledge to other people.
See if you can find a copy, I think it's on DVD (and on "those" sites where you might find movies )
