It's likely related to the oops update to cooking a few days ago, what with rollbacks and whatnot. I had to go through and re-adjust my auto-feed settings as well.
If you need any context, you can see this post about the update that accidentally pushed through coding from the test site and then this post that addresses the intentions to rebalance food and the cooking profession.
Any time they adjust anything on the back end related to food items, those affected will have their auto feed settings returned to the default values. It would be better if auto-feed was just points-based and you could choose to dump points into it yourself, which would eliminate these problems completely & indefinitely, but ¯\_ (ツ)_/¯
