Dietary Advice Needed

I am now requesting some assistance from my readers, seeking your advice on an important matter.  A close family member is currently undergoing a very restrictive diet and I am seeking some suggestions and recommendations that will help him deal with this diet.

He may not eat any food products that contain the following: wheat, dairy, corn, peanuts, tree nuts, egg, soy, fish, shellfish and beef. Yes, that is quite a list!  That would be a hard list to follow for any person.  

So, I am hoping some of my readers could offer some suggestions.  Where are the best places to shop for food products meeting those restrictions?  I would prefer locations that are within a range of 15-20 miles north of Boston.  Can you recommend specific products or brands?  Today, I visited the Natural Food Exchange in Reading, and did find some foods, but am unfamiliar with the brands so don't know which tastes the best.

Do you have any suggested recipes? Are there any websites which would be good to check out? Any help you can give would be much appreciated.
