As I am not a health care professional I can't tell you whether or not something is safe but I can share my experience. I have found that whole seeds are more difficult to digest but I tried grinding anise seeds into a powder and made a tea. I use a mortar and pestle. I use Dijon mustard in dressing/dip recipes. If I liked celery seeds on my eggs, I would try grinding the seeds into a fine powder. I am also a lacto ovo vegetarian and have lost a lot of weight recently so I try to focus on calorie dense foods like homemade guacamole and a thai peanut dip that I can put on gluten free crackers or celery that I have de-stringed from both ends. This works for me but may not work for others. I love the veggie burgers but can't do a whole burger but I am going to try 1/4 one. I keep a list of foods and my reactions. I find that I can't eat a normal serving size so I put small amounts on a small plate, chew excessively, eat very slowly and drink water with meals. That seems to help me. Hope you find something to eat that you can enjoy. Best of luck.
