Doesn't seem like it is after some looking. Not liking one type of food because of texture isn't enough for a diagnosis, at least according to this criteria:
"According to the DSM-5, ARFID is diagnosed when:
An eating or feeding disturbance (e.g., apparent lack of interest in eating or food; avoidance based on the sensory characteristics of food; concern about aversive consequences of eating) as manifested by persistent failure to meet appropriate nutritional and/or energy needs associated with one (or more) of the following:
* Significant weight loss (or failure to achieve expected weight gain or faltering growth in children).
* Significant nutritional deficiency.
* Dependence on enteral feeding or oral nutritional supplements.
* Marked interference with psychosocial functioning."
If they're meeting their nutritional needs with other foods just fine, they don't have this disorder.
Like take my wife as an example. She refuses to eat several foods because she doesn't like the texture (fish, solid fat on meats, cottage cheese, a bunch of other foods I don't remember offhand). But there's plenty of other things she will eat, and she doesn't have a nutritional deficiency.
Do note how the criteria actually only require one of the former and one of the latter group. If your wife avoids foods AND doing so causes psychosocial distress (such as not being able to eat with coworkers and consequently getting excluded) then the diagnosis does apply.
In my wife's case, at least, it doesn't cause her psychosocial distress. It just means I usually have to wait until she's got other plans before I can order from a sushi restaurant (I say usually because sometimes she's fine with getting a noodle dish). None of the bullet points apply to her.
In fact, I had more trouble finding food I could eat at restaurants when I was on the keto diet (and many years earlier when I was on a vegetarian diet), then she does right now.
The parent poster also didn't mention anything about it significantly interfering with social functioning.
