I couldn't remember if it's been discussed here and the search function is hair-pullingly frustrating (and that's being kind).

We watched this on the weekend. It's an Australian film that delivers observations and information in a very easily digested format. The man putting his body on the line has close medical and nutritional supervision. The differences in his blood work speak volumes all on their own. It isn't very scientific but gives a very good all round, easy to watch account of how sugar can affect your body.
The hubby watched it with me and as soon as it was finished talked about giving up Coke and the breakfast cereal he enjoys daily. I've been gradually eliminating most added sugar from the house and it's been quite successful. Except for the teenager who still brings home a 600 ml bottle of Coke twice a week. Sometimes he swaps it for Coke Zero because his friend drinks it. Despite this, on the whole, sugar is a treat. I'm going to have the kids sit down and watch this. I think it will surprise them just how much sugar can affect your body. They already read labels. A habit they've picked up from me. I make it easier to convert grams to teaspoons by saying to divide it by 5. It's easier than dividing by 4 and gives them a fairly good idea of how much sugar is the product.
Watch it. Kids over about 10/11 yo would gain a lot from it as well.
