Hey woman there are kinds of which are sweetThat's an acorn. Acorns contain tannins that can cause upset stomachs. They are very bitter tasting. Personally I wouldn't eat them.
Edited to say that dogs, cattle and horses can get really ill eating them.
its why the new foresters put pigs out into the forest. the ponies would eat them and get sick. plus it was free food. they are eaten if processed usual in times of famine. which may be a warning. there according to the web are nicer tasting ones. the bit i found interesting and may be wise to remember if going foraging 95% are infested with insects. so extra protean. still not sure what you would want to eat them for.I had to Google that Quercus name, it's just a Acorn which pigs like to have a munch on if I remember rightly from my younger years living in the UK.
Best of luck eating them as they were bitter as all sh*t from my attempts at trying them as a kid.

I remember reading somewhere or other, that people made ersatz coffee out of acorns during the second world war in Germany.still not sure what you would want to eat them for.
Pigs were good at sniffing out and eating Truffles as well, so the bacon would have been real tasty in the "olde" days.Once the acorns were gone then the pigs were rounded up and taken away to become bacon,
Enjoy eating them.Hey woman there are kinds of which are sweet
Dogs sometimes even eat bread and meat
