Happy Kwanzaa

Okay, call me a skeptical old geezer, but I started looking into this holiday recently when I realized I hadn't heard a thing about it when I was little.
It turns out it's relatively new, thought up by a cat named Dr. Maulana Karenga back in 1966. Based on African culture, the holiday's origin centers on the Zulu first-fruit celebration, which is supposed to last a week and occurs as one year ends and another begins.
Kwanzaa has caught on all over the world, according to Karenga, but I can't say I know anyone who actually celebrates it.
All the African Americans I know are Christians, so I have never seen Kwanzaa celebrated. I wonder, do they get presents? What's the dinner like?
Before I accept it as a legitimate winter holiday, I'm going to first have to know if there's anything good to eat. If there's not, then I say Kwanzaa, Shmanzaa.
If anyone has any direct experience with this holiday, please enlighten me. I don't care about the history or the details, I just want the 4-1-1 on any food and presents the holiday includes.
