Are acorns from oak trees poisonous?

Don't blame me if you die from eating them but I've eaten them before. I just cooked them first. I can't remember exactly what I did. It was a project for school a long time ago based on some native American dish involving acorns. I would suggest that you boil them really well and check for worms before you eat any of them but I think you're safe. Theoretically, you can eat anything if you just cook it long enough. Too many acorns will most definitely give you the scoots though so... use moderation.
