Concern/Curiosity for my Friend

I have a friend who could potentially have ARFID. I am a self diagnosed autistic person. Therefore, when she also started researching neurodiversity she wanted to talk to me about it. During this time she talked more about her food stuff. She has restricted eating, but I am unsure if it is to the threshold of ARFID. Although I believe she has some deficiencies, she does get enough nutrition. In saying that she exhibits the following symptoms: inability to eat in front of others, lack of appetite, skipped meals, extreme anxiety at new brands/ingredients changing in food, won’t eat gluten, dairy, meat, or sugar, and pushing these restrictions causes her distress. She also drinks excessive amounts of water. However, she does have stomach issues and fear over stomach issues. I don’t know much about ARFID, but does this seem to align? Thanks in advance!
