Picky eating is not uncommon at all. It's common with AS. Just google picky eating and Asperger's or Autism and you'll get a lot of results.
E.g. Fussy Eating:
Quote:
Children with an Autism Spectrum Disorder often have sensory problems. The brain's filtering mechanism can work differently in assimilating the senses such as touch, smell, hearing, taste and sight. They may be extremely sensitive to certain bland tastes, or possibly oblivious to strong tastes such as chili.
A child can find the very feel of a fabric against their skin very unpleasant, in the same way that the texture of a particular food could be almost painful. Conversely, foods with say a crunchy texture may be loved, while any other texture is rejected. This kind of sensitivity can also extend to temperature, where food may only be acceptable at a precise temperature.
I'm a picky eater and people find it strange, too. Always asking me about my food choices and eating habits, it can be annoying.
