Long story short, it turns out that they're actually not very good at all. On a nutrition-per-pound basis, the ranking goes like this (from best to worst)
- Salted Fish
- Dried Meat
- Bread
- Biscuit Ration
- Apple
- Yambi Berries
- Steak
- Rat Meat
- Bittercup Seeds
- Meat Scraps
- Wild Potato
- Cabbage
- Meaty Spider Legs

- Salted Fish
- Yambi Berries
- Wild Potato
- Bread
- Rat Meat
- Cabbage
- Apple
- Biscuit Ration
- Steak
- Bittercup Seeds
- Dried Meat
- Meaty Spider Legs
