My biggest issue with food is that there are surprisingly few alternatives to raising strength. It's boar meat or boar meat.
There seriously needs to be more food alternatives to increase strength, Soy or Tofu at least.
Also, I noticed on the food chart that bread and apple pie increase con but are only 2xp points apart from each other.
Butter may be unlimited from cows/milk but it is that extra step that makes it ridiculously inefficient to increase con when you can just kill a cow, make sausages, and bam, twice as fast.
