I just started playing the other day and have been eating pretty much nothing but Constitution increasing foods.  Now, here comes my dilemma: I read that you need 25 Charisma to start a village but its going to take me a long time to get my Charisma up that high or any of my other attributes up because I have high Constitution.
Is there any item or food or something that has negative stat affects? If not then would food that is not stored properly or left out go bad and have the reverse effects on that attribute it would have normally increased?
example: if I eat rotten Cow Chorizo (that's what I have been eating) by accident I have a chance that when I fill my Food Event Points bar it has a chance to reduce my Constitution.
