This paper is huge. One of the arguments the food industry advances is that sugar consumption has gone down while obesity has gone up, so it can’t be sugar. This paper uses a complex statistical analysis to show that US obesity is a function of both current sugar consumption and an derivative of the sugar consumed by the previous generation going forward. In other words, it’s the economic equivalent of “epigenetics”. This is yet another nail in the coffin (as if we needed any more nails)!
