There's also the changelog for Alpha v0.163 https://thelongdark.fandom.com/wiki/The_Long_Dark/Early_Access_Changelog#0.163, released in November of 2014, which states:

"If left untreated, Food Poisoning will now degrade Condition to just before the point of death." (which is 15% health)

This damage cap has been in the game since way before the full release. There's no relevance of information this ancient on the wiki, and it only misleads readers.
