In my first campaign I put a lot of efort into defining the diets of the various races.

- Halflings are insectivores, and most of their crops are the kind that contain very little nutrients (such as potatoes, rice, and sugar). This accounts for Halfling's slim figure.

- Elves respect nature to the point where they refuse to eat plant-based products. They consume only food that comes from animals.

- Dwarves garnish their food with pebbles and small rocks.

- Gnomes garnish their food with small gems, this is the reason that Gnomes split off from Dwarves in the first place, they were originally the same race.

- Orcs are very interested in agriculture, and much of their diet is dairy based.

- Goblins are completely carnivorous.

- Gnolls are also carnivorous, but prefer to raw flesh from either very young specimens, or rotted flesh from extremely old specimens. The consumption of raw flesh from young victims is based off personal taste, but the consumption of aged, rotting flesh is an effort on the Gnolls part to preserve population of the groups they feed on, so as not to eat all of their enemy's potential breeders.
