I'm worried. I've just seen a private preview of a new eco documentary, Robert Golden's This Good Earth, which is released Jan 21. In it doctors, scientists and academics are warning our much-sugared diet is set to destroy our kids, with babies as young as 2 months having diabetes and obesity rates rising from 3% to 25% in 25 years. The film warns that we are eating ourselves to death, should we be more actively campaigning for sugar to be somehow officially rationed, like banned from all school meals?
