I think sugar demonization is gonna be yet another fail by nutritionists. In 10 years time they will say, oh actually it turns out that sugar in moderation stimulates the brain directly and increases focus. Its especially useful to animals that rely on cognitive function, like humans.

It will be one of those facts we will all immediately recognise as obvious in hindsight and wonder why we went along with the fad of cutting out sugar, which had a detrimental effect on our ability to think.

Meanwhile, nutritionists will have moved on to saying calcium isotopes are shortening our lifespan.
