acorns are nuts, but they don't seem to cause allergies in people. They are hard, dry pods sort of like chestnuts and hazelnuts. And did you know that one Canadian province, Prince Edward Island, has three oak trees on its flag?
anatomy was named after the acorn? It's the "glans" which is Latin for acorn. In the 17th century, apparently the English thought it resembled the part "down there" and no, I won't be including a picture!
Not only squirrels, but also deer eat acorns in the fall. Mice, woodpeckers, blue jays and ducks like to snack on them too. Even bears! Oak trees depend on these animals to carry the nuts to other locations and bury them so that a new tree will grow in that spot.
Acorns are packed with nutrients so it's not surprising that people from different cultures have been eating them for thousands of years. Some acorns are 18% fat, 6% protein and 68% carbohydrate, equivalent to modern corn and wheat. They are also great sources of vitamin A and C. You have to be careful about the tannins, though. Tannin is a bitter chemical that we humans use to tan leather. Acorns are not really that good for you raw because our sensitive intestines can't get the nutrients out of them.
