Fat - an evolutionary issue

I find it unlikely that Garth George has any real understanding of evolution but he does stumble on the main problem with modern food availability and our evolutionary acquired taste buds - Move over Darwin, here's a new evolutionary theory .

We like fat and sugar because in the past they were in short supply and, because of their energy value, highly important for out survival. Now we are able to produce these substances with ease but still are inclined to eat them as if the supply will run out tomorrow.

Not sure if he was being serious about childhood infections. But he is definitely wrong there. We are engaged in a perpetual Red Queen standoff with microorganisms which is why we have sex.

Did you know that 80% of the biomass of the planet consists of microorganisms? They should go on a diet.
