Sadly crash landing is a bit more complex then that.
Spice of life is installed and active. There is a log of 20 "eat" that is tracked. If what you are eating happens too many times in that log, then you don't regain as much from it.
So you require 5 foods to rotate between, the last one passing out of the book as you finish the last of them. The good news is that this is not hard.

That's a nice big topic, not quite as big as the big big topic, and the advice is being consolidated into the first post.
Try experimenting with the harvestcraft food preparation tools and you'll be able to find things quite easily. Bones for stock. Spider eye soup. Rice into flour. Flour into bread. Bread into Toast. Zombie Jerky.
That's five really easily and early.
Watering can is enabled, so growing crops is pretty easy.
