I have particular tastes also. I was called picky when I was a
child (but am no longer as picky). One thing I learned about
that shed a lot of light on this whole picky eater thing was the
whole concept of the SUPERTASTER.
Here's the Wiki:
http://en.wikipedia.org/wiki/SupertasterIt explains why many picky people avoid certain foods, which,
in many cases, are foods from the same short list.
Different people have varying amounts of taste-buds. Fancy that.
I know many who say mushrooms are the greatest food ever,
but to me they taste like dirt. I think maybe these people have
less taste buds. Just kidding. Tastes vary from person to person
also, but I do think that many people out there have a "dulled"
sense of taste compared to the supertasters (Count me as one.).
It is analogous to varying degrees of visual acuity across the
population. Do we all have 20/20 vision? I think not. Is your
taste acuity 20/20? 100/60? 200/180? You might be able to tell
if there's a bird in that there tree across the street, but I can tell
you if there's bay leaf in this here gumbo.
As for any connections with AS, I agree with what
Lepidoptera wrote:
Aren't food issues just like any other AS trait?
Taken by itself it doesn't mean anything and can easily be explained
away but when added to the many other traits it's part of the picture?
I don't have the equipment to figure out if there is a genetic link
between ASD and supertasting. But if I did I'd get on it right now.
I'm a supertaster : ) I wish it had a more clinical name because I feel a little stupid when I tell people I am.
