I received an e-mail today that taught me some things:

Christmas trees are edible. Many parts of pines, spruces, and firs can be eaten.  The needles are a good source of vitamin C.  Pine nuts, or pine cones, are also a good source of nutrition.

I’m not sure about eating pine cones…

If you have any experience with eating Christmas trees, we’d like to hear about it.   I’ve never heard about such things before…

But I reckon if you have a live Christmas tree and you can stomach it, that would be free food, since you already had the tree anyway…
