The effect of eating ingredient items (such as raw meat and fish, fruits, and other unprocessed foods) will be changed. Eating such items will only grant an experience point bonus.
I hope I'm reading this right and that the bonus is to experience points gained for a time and not a bonus of experience points themselves. Otherwise we're going to have a bit of an issue here....

Edit: I am glad though that with the medicine reforms they're not turning the game into a potion chugging contest. Strong, short-term bonuses with long cooldowns. I approve.
