Blame your sweet tooth on natural selection
My cat eats cannoli cream — in fact, she’ll down the entire cannoli if given the chance. Apparently, she is either the missing link (lynx?) or not the most evolved member of her species.
The Smithsonian Magazine blog recently interviewed evolutionary biologist Jason Cryan, who explains why we crave sugary foods — and how it seems as if every animal has a sweet tooth except for cats. Although I might disagree with Cryan on his theory about animals, I was fascinated by his suggestion that a preference for sweeter food can be detected at the microbial level: experiments have shown motile bacteria moving towards sweeter solutions.
