How often do you think our ancestors ran across fruit? You basically enjoyed them once a year and even then they weren't the same kind of fruit we have today. What we have today is super fruit in size and sugar and availability 24/7/365.

My ancestors died at a ferociously fast rate. Living the same life they did sounds like a bad idea for me.

Various kinds of fruits are actually available for quite a lot during the year.

I think it's more significant that wild fruits, grains, etc are quite different than what we have cultivated. I.e. wild strawberries are extremely small and many of the fruits still eaten by primates and other animals are really quite bland.

I find it a paradox that everyone seems to know our food is unhealthy for ducks..

Wild strawberries taste waaaay better then ones from store. It is actually our contemporary fruits that are super bland - they are cultivated for size and look. Not for taste and not for nutrition.

That being said, strawberries are absurd choice of fruit. They don't last.

Already apples last. You can even store them without that requiring anything modern. Bananas is another good example. In places with warm climate, you have fruits year round.

Except modern fruit variants are not what we evolved to eat. Some zoos have stopped feeding fruit to some animals because they are too high in sugar. https://qz.com/1408469/humans-have-bred-fruits-to-be-so-high...
