My sister recently found out she was allergic to corn... very allergic. She developed symptoms very suddenly.

Wow, Benny. I was curious about the corn allergy, so I goggled. Much insight, but I'm sure you came across this blog by a womn who has the same allergy: http://www.cornallergens.com/list/corn-allergen-list.php At least she why she hasn't been feeling well and that there is something she can do. You're a sweet bro!

I agree cookbookchick! Without a trusted source for scratch cooking, she'd be in much worse shape. Corn and its derivatives are in E V E R Y T H I N G pre-made, with about a zillion ingredient aliases. Perhaps start by printing out and carrying a list of those aliases for food shopping? In addition to closely monitoring everything that she consumes, she may need to put some effort into repairing damage done to her GI tract as a result of the allergic response. Lots and lots of bone broths for the nutrition and healing gelatin, and raw milk, especially colostrum if you can get it. Perhaps also seek the guidance of a naturopath/functional medicine doctor to check for leaky gut, which may have created the conditions in her body that allowed the sudden onset of the allergy. I know it feels like a diagnosis, but it could actually be a symptom of a broader underlying problem. And, if you aren't already familiar with the Weston A. Price Foundation, and Sally Fallon's work, I highly recommend it as preventative medicine going forward. Good luck!

I'm sorry I don't have any advice to offer you, Benny - I just wanted to say how fortunate she is to have such a loving, caring brother.

So far, I'm starting by making her all the usual condiments that she cannot buy anymore. Ketchup, mayonaisse, etc.. I also bake her bread
