Milk

Milk is a white liquid that has a lot of Vitamin D. Milk is made specifically for newborns who can't eat anything else, but for some reason, conservative adult humans like it. It tastes pretty bad, but it's used to make foods like ice cream and cake which taste really good.

Milk goes through quite a few different process. First, it comes out of cow breasts. Afterwords, it is heated to kill bacteria; a process called pasteurization. Then it is creamed and homogenized. And then it goes to your local Wal-Mart.
