Ask your doctor for a referral to have your daughter evaluated by an occupational therapist who specializes in sensory processing disorder. An occupational therapist can work with your daughter to better help her regulate her senses so that mealtime and grooming time is not so difficult.
My son also is super sensitive to a number of different foods and, I think because of it, he rejects most new foods (except for a handful and items) with even tasting it. It's an on going battle but here's what I do to get him past his defensiveness:
1. Put a little bit of the food on a fork or spoon and have him smell it. This is always greeted with a very loud, "It's yucky!"
2. After he smells it, next he has to kiss it (get a touch of it on his lips), after which he'll let out a second really lound, "Yucky!"
3. The final step is to have him taste a little bit of it. At this point he will either let out a 3rd and final "Yucky," at which point he's off the hook for that particular food item for that particular dinner. More often than not though, he will let out, "That's delicious!" and gobble the whole thing up.
4. If he rejects something, I just keep on reintroducing foods over and over again. I have learned that there are some foods that he just can't tolerate like bananas. He will gag at the smell of them so that is the one food that I won't put on his plate but he's okay with eating banana pancakes as long as I mask the smell with cinnamin and nutmeg.
Anyway, this is the trick I use. Also, with regard to eating fruits and vegetables, for both of my kids, they are more inclined to eat the healthy stuff if we make it fun for them. We call broccoli "little trees" and my husband and I will often joke around with our kids during dinner, "Cameron, No . . . Don't eat the trees!" all dramatic and silly like, while he starts chomping away at it, giggling at the same time. If you make dinnertime playful and fun, it becomes less like a chore and a battle ground.
Hope this helps.
