Modern fruit isn’t especially healthy:
At the Melbourne Zoo, the monkeys are no longer allowed to eat bananas. And the pandas are getting pellets instead of plums. In fact, fruit has been phased out completely. That’s because the fruit that humans have selectively bred over the years has become so full of sugar the zoo’s fruitarian animals were becoming obese and losing teeth. -source
I’m in that country and can’t disagree. I was just paraphrasing the line from the Joker movie to a friend of mine,“We’re going to get exactly what we deserve.”
