ELI5: why are the skins of fruit more nutritious than the insides?
gpt
because fruit aren't intended to be nutritious, they're intended to be tasty, which means the bulk of them is relatively homogeneous fluff with lots of sugar. The skin is the only part which has to actually do something important, so its loaded up with a variety of vitamins and minerals and other cellular necessities to do its job.

same applies to like, why wheat germ is more nutritious than the rest of the grain. The rest of it is just an energy store. The germ has all the parts that grow and do stuff, so all the goodies are found there.
