Nutrition

is all food equally calorie dense? does a can of bannana flesh have the same nutritional value as a can of pea soup?

also from the weapons stick, this is my favorite line:

adamantine quarterstaff +16 [32000g, DAM 24-41, extremely accurate, almost unbreakable]
Can 2-hand at 775 ASTR, 1-hand at 6196 ASTR

No, each food has their own nutrition value - it's easy to check from the script files.

I wrote a section on exact nutrition calculations over on the wiki, under "Eating"
