If squirrels can eat acorns then why are they poisonous tou us and other animals?

Acorns are not poisonous to humans or other animals, including squirrels. In fact, they are a nutritious food source that has been consumed by humans for centuries. However, acorns do contain tannins, which are a type of phenolic compound that can give them a bitter taste and may cause digestive problems if consumed in large quantities.

Additionally, some people may be allergic to acorns, so it is always best to check with a doctor before eating them, especially if you have any concerns about potential allergies.
