In the Forgotten Realms, how did elven populations feed themselves?

I’m building a world for a future campaign, it will feature elven civilizations. In order to place and design cities, I wish to know how FR handled food in elven populations.

1. What do elves eat? Are they vegetarians, meat eaters, mix of both?

2. Did elves practice farming? Are there stories of elves cultivating fields, planting crops…

3. Did elves raise livestock?

4. Do elves eat as much as humans?

To be more clear, I’m specifically interested in examples from sources canon to the Forgotten Realms, or from rule books.
