Legal Question in Family Law in California

Generally, parents have a duty to support their children until they reach 18 or graduate high school (i.e food, shelter, health care). Otherwise, they may be in violation of various child neglect or abuse laws. Do parents have to physically "cook food if your under 18?" Probably not if the child is old enough to prepare her own meals or meals for the family. I doubt that requiring a seventeen year-old to prepare a meal as a chore would amount neglect or abuse. My answer would be different if the child was under ten.

Nope. They have to provide you with edible food. That's it. If you can cook it, they can make you cook it if you want to eat.
