Fat-free or sugar-free? The verdict

Back in the last century, there was a big turf war in nutrition about the cause of the increasing incidence of obesity and cardiovascular disease.

In the end, Keys won out – a decision that had little to do with scientific research and lots to do with money, politics and power.
