They were eating rats in the first season. Now they are given rice, chickens and money to buy food. You can even skip the challenge and get something to eat while laughing at the other players go for the immunity necklace.
For the first five or six years there was no one that I hated so much that I would stop watching because of them. Then season after season they started to have the one person that should of been voted out the first few weeks but some reason the biggest drama queen keeps on the show. The worst one was the drama queen that from "one world" that faked sick to get off the show. Then they brought him back to watch him walk off the show again. The show is full of these types now.
