Alright so, I don’t know if this is already a thing, but it wouldn’t be nice if eating certain foods (such as the herbal tea) positively added to health, it would give a purpose to most of the cooking recipe since most of us survive on cooked meat anyway.
Herbal tea gives +1 to your hidden health stat. Pine needle tea gives +3 to the same stat. Just don’t be afraid to look into the JSONs for your answer.
To expand on that, https://github.com/CleverRaven/Cataclysm-DDA/blob/master/data/json/items/comestibles.json is the food and drink comestible json, and “healthy” is the attribute you’re looking for. I know it protects against flu/cold, but I don’t know what else it does.
Hit point regeneration during sleep, broken body parts mending and infections from bites or spores.
