How severe is her allergy? Is cross contamination a problem?
The reason I ask is because if cross contamination is a problem I would not reccomend going to Whole Foods.
I am allergic to peanuts to the point where I cannot eat anything that is produced on the same line or in the same factory as peanuts and I find that most of the things such as granola, granola bars and cookes have a MAY CONTAIN or MADE IN TEH SAME FACTORY warning.
Personally, I am able to find more things at our regular grocery store than at whole food and the prices at whole foods are ridiculously high IMO.
Some examples of what I eat:
CEREAL: cinnamon toast crunch, shreaded wheat, apple cinnamon cheerios, corn pops, frosted flakes
ENGLISH MUFFINS: Thomas' English Muffins (I love the cinnamon raisin english muffins)
BAGELS: Thomas' Bagels (I find that they are pretty good for packaged bagels...obviously not as good as fresh but they are an acceptable substitute)
CRACKERS: what type are you looking for? If plain crackers I eat: Club crackers or ritz crackers. If snack type crackers I eat: Wheat thins and triscuits
Granola Type Bars: This is much harder. I have yet to find a granola bar that is safe for me. There are peanut free ones but not cross contamination free because peanuts and peanut buuter are such common granola bar ingredients. I do like Nutri-grain bars for a quick breakfast or snack though.
When I visit my grandparents in West Palm Beach, FL I am able to get everything at Publix.
Walmart might have all of the stuff as well...or at least some of it (I don't know for sure because I don't shop at walmart) but I would avoid Whole Foods unless Organic is extremely important because I find them ridiculously expensive...JMO.
HTH.
