Our DS9 (2E, Asperger's) had significant food issues. For him, the cause is not primarily sensory, but rather anxiety; novel foods made him anxious, so he restricted his diet. His anxiety about food goes up and down in parallel with stress and anxiety in other areas of his life. However, we have made huge progress in this area. We had to work on flexibility in other areas of his life before we could tackle the food issue-- it took a lot of doing, but he eats well now.
Feeding therapy programs vary widely in their quality. I'd give preference to one that is multidisciplinary (includes a team of OT, GI, etcetera, so you know you aren't missing something).
Around here it is no problem to get OT for feeding alone without other motor issues; again, though, not just any OT has the expertise to actually succeed in this. We know of one truly qualified OT for feeding in our reasonably large city, whom we found through a specialty feeding clinic.
Ultimately we got much further on this problem through behavior therapy than through OT. The successful OT had not just regular OT training, but also quite a bit of knowledge about behavior therapy; and our separate behavior therapist (not an OT) got us the biggest gains of all.
