I had the same thing, and I ended up growing out of it in my early 20's. The gag reflex is so tough to get around, I think I gradually got past it around the same time. I'll never be an adventurous eater, but I've become a huge fan of asparagus, spinach and green capsicums (bell peppers).

To be fair, I think around 10 my best friend at the time (Japanese) and I were picking the "worst" nigiri off the menu for each other to try.

You eat a raw clam with a "tail", and everything else relatively adjusts itself, re: gag reflex.

What about smoothies? Will she eat veggies if you blend it all in NutriBullet with some tofu, dates and banana? It's different visually and texture.

Sometimes. She's unpredictable when it comes to smoothies.

Does she have a sensory processing difference that makes some foods taste disgusting?

I'm obviously not sure what your daughter's situation is, and it sounds a bit more extreme than mine was, so take what I'm about to say not as advice but just as a different perspective.

When I was a kid, I hated the texture of most foods. They made me gag. It wasn't necessarily the taste, and I really did wish I could eat vegetables because I knew they were good for me. They even smelled and looked good. But I just couldn't get past the texture.

My pediatrician was "old school" and told my parents that I was just a picky eater and not to worry about it. Did I eat dairy? Fortified cereals? Eggs and meat? If so, I'd be fine. His point was that kids just need macronutrients, and the vitamins sprayed on cereal plus a daily supplement was more than enough.

Did I under eat as a result? Probably. Was I a little under weight? Yeah, but not dangerously. Honestly, it probably helped me long term because my weight has never been a problem as an adult. I'm also normal height.

So, did I have an eating disorder? I mean, in a way, maybe. But it was a reaction to a sensation. I didn't have any other reason past "it feels gross in my mouth." I'm not an expert, but doesn't disordered eating need to be accompanied by "wrong thinking?" I had no other cause or motivation for my picky eating.

> she seems physically healthy; she runs and plays and doesn't get hurt

Again, I'm not trying to give advice because I don't know the specifics, but maybe don't worry too much unless she is actually presenting as physically unhealthy. Like, unless blood work shows some nutritional deficiency that can't be corrected with a vitamin supplement.

> She has been seeing a therapist, but I wonder if she needs to see a different therapist

Again, I don't know your situation, so maybe she is seeing a therapist for other reasons - but I believe that being made to see a therapist as a kid for my picky eating would have made things worse, especially since I didn't have any other problems. It may have even made me believe I had other mental problems.

I just didn't like the texture of most foods. Even as a kid I realized how weird that was, and that I should be eating more foods. I just couldn't do it physically until I was older and outgrew it. Now I'm fine. I'm an adventurous eater. I eat anything and everything, and I'm quite healthy.

Side note, I have adult friends who I learned were even pickier eaters than me as kids and who never really grew out of it. They're all fine, if maybe a little underweight.

There's evidence suggesting that super restrictive diets can extend lifespan. Also, hey, some people are just a little bit eccentric and have weird eating habits. Maybe they don't need to be "fixed." ymmv.
