That Sugar Film

That Sugar Film (2014) is an Australian documentary you can watch online on iFILM, directed by and starring Damon Gameau, who spends 60 days eating only foods labelled "healthy" — no fast food, no candy — to track exactly what happens to a body that's already in good shape.

The rules of the experiment are tight. Same calorie count as Gameau's normal diet; every item purchased off an ordinary supermarket shelf carrying some version of a health claim. Low-fat yoghurts, fruit juices, muesli bars, flavoured milks. Medical checkups document what changes week by week. Gary Taubes and other researchers explain the biochemistry, while footage from rural American communities shows the long-term version of what Gameau is running on fast-forward. Stephen Fry turns up to provide sardonic commentary along the way.

What makes the film work is the physical evidence. The changes in Gameau's bloodwork and liver function don't require persuasion — they're just there on screen. This is the kind of documentary that makes you look differently at the back of a cereal box. Stream That Sugar Film (2014) online on iFILM.
