Confused

I never had a problem or was thinking too much about the food I was eating but lately I have been thinking and obsessing over it. Its not neccessarily an issue as I am still eating foods but sometiems I will eat something and feel imesnely bad about eating it after. I am not quite sure what it could be and I was wondering if anyone else has this problem. I also have anxiety if that gives any insight maybe its stemming from one of my anxieties. I am not sure.
