I do but it’s not really a structured thing and is sort of hard to explain. A lot of it is based on my personal herbal and food correspondences mixed with DIY culture, being punk and vegan. I also do a lot with food colors and cooking with the seasons. It’s mostly for nourishment, but I’ve also worked with teas, brewing beer, making bread for holidays, and decorating a kitchen altar. We get a box of organic veggies delivered every two weeks and I do a sort of experiment sometimes where I pick a specific ingredient and search out recipes that are new and exciting. I treat food like and experiment, just like magic!
I would suggest maybe starting to read about correspondences with herbs and kinds of food. There are a lot of those listings on line. I do have the Cunningham books Wicca in the Kitchen and Encyclopedia of Magical Herbs, that’s where I started. Any starting place is just that, a starting place. I also have a couple of magical cookbooks that focus on cooking with the seasons. (here’s a link to my witchy book collection. I’m working on putting them in categories)
I’m not sure how your disordered eating manifests so I don’t think I can get too specific and I’m also not a doctor. Maybe researching specific ingredients that interest you or specific plants or food that are native to your area. Read about this history or apples for example or how many ways mint can be used in food. I’m sorry if my strategies seem more mundane than magical but I believe our curiosity tells us something about ourselves and that the things we are seeking or things that we need or the understanding we are looking for will come from study, patience, and listening.
