Maybe a list of foods considered as "raw" could help.
Anything that isn't cooked or preserved would be raw, Taddeus, but as I think we talked about, in extreme hunger situations, people will eat raw foods. Uncooked crabmeat and uncooked eggs would be great examples. In societies where food is eaten fresh and livestock living and slaughtering conditions are fairly clean, people eat raw eggs, milk, and even meat with no harmful effects.
I have several ideas to update a little the hunger scripts (and possibly even the thirst and sleep ones), but I'm not sure about them and I'd like some feedback.
The first one is following. If a person doesn't eat for 1 day, he/she'll need to eat a certain amount of food (let's say 10). But if a person doesn't eat for 5 days, will he/she need to eat 50 at once to recover? Or something in between, for example 30-35, would be enough? The same question applies for thirst and sleep.
I would say if you were going to change something, the frequency of eating would be the thing to change. Someone who has been going without food, who just sat down to a big meal and gorged himself, would almost immediately throw up. His system wouldn't be able to handle it all. If he was to eat a little at a time, but say every three or four hours, with frequent naps, he could re-build his strength slowly and without causing more problems. I don't know how complicated it is to mod this, but if someone has heavy penalties, and they really wanted to roleplay it realistically, then requiring more frequent meals and sleep to remove the penalties would be more accurate than eating and sleeping to make it up all at once.
Anyone who complains about the heavy penalties or whatever method you decide is best to alleviate them, might just need to turn the hunger and fatigue scripts off. As for thirst, I think there should be a maximum of water a person can consume in one sitting, especially if they have no food, because this can cause a fatal metabolic breakdown. Alcohol would come with it's own hazards. However, fruit juices and milks would be safe to drink in large quantities to remove heavy penalties, but it would still take some time (a few hours) to reverse the effects of dehydration.
