Let's talk about murderfood and murderdrinks.

People dont use food for it's healing effects because by the time you need it you've already passed the injury threshold that makes it useless (survivalist is actually pretty useful). It doesn't get eaten for fun because it's boring. Effects better than "Gives you a horrible disease that kills you!" etc might make people interested. The food and drinks page on the wiki being out of date and missing information probably doesn't help.

Then again I've left cryoxadone ice creams on the bar counter all round and not even dying players stopped to eat them. The lollipops in medbay also go completely ignored despite bringing me to full health from crit on several occasions.

Theres also the situation with medical supplies and donk pockets being literally everywhere on cog2 making food healing less relevant.
