+title: allergies
+---
+
+## Basic Info
+
+Allergies are based on the vitamins system for the purpose of inheritability and avoiding a need to
+create several variants of items / make tough calls as to the material of foods.
+
+As an initial measure, these vitamins were applied based on materials to prevent regression and
+having to add the vitamins all by hand. However, unless an item has `NUTRIENT_OVERRIDE`, cooking
+_should_ correctly reflect what actually went into it. Naturally spawned items will have whatever
+their materials would indicate.
+
+If a food item has veggy allergens in it, a carnivore will be unable to eat it. Vice versa for an
+herbivore and something with meat allergens.
+
+## Current 'allergens':
+
+- `"egg_allergen"`
+- `"fruit_allergen"`
+- `"human_flesh_vitamin"` (This one is a special case, as it's instead used for morale maluses /
+  boons due to Cannibalism)
+- `"junk_allergen"`
+- `"meat_allergen"`
+- `"milk_allergen"`
+- `"nut_allergen"`
+- `"veggy_allergen"`
+- `"wheat_allergen"` (Actually just general bread / baked goods)
+
+## Current dietary restrictions:
+
+Full bans:
+
+- Carnivore: veggy_allergen, fruit_allergen, wheat_allergen, nut_allergen
+- Herbivore / Ruminant: meat_allergen, egg_allergen Dislikes:
+- Vegetarian
+- Anti-plant
+- Lactose intolerance
+- Fruit intolerance
+- Junkfood intolerance
+- Grain intolerance
