I don't try to judge others food choices. We have a co-worker with a gluten allergy, she will make gf cookies and bring them to work. I always try one. They taste different but not bad. The only time I talk to her about her food choice is if I notice something she is missing has added gf options. I went to a burger place (she said this is one that is hard because her 9 year old loves burgers) and I saw they do gf. Her son loved the place and she loved the burger. Otherwise I may just ask if I am going to lunch if they have something gf she would like.

Everyone constantly asks my husband (Cat 1 racer and a crohn's patient) about his diet. "You can eat that?" When he slims down for race season they start asking if he is sick. It does wear on him.
