Facts on Food Hypersensitivity to Corn
This handout was published
by the now defunct Allergy Asthma Association of Alberta in 1987.
Some of the information is probably outdated by now but at least
it will give you some ideas of where to look for corn sources.
A person who is hypersensitive to corn must
avoid corn and all corn derivatives in food and non-food items.
Simple avoidance of corn as a vegetable is not difficult, it is
the avoidance of corn derivatives that is a challenge to the person
hypersensitive to corn. Some individuals may be able to tolerate
corn in its vegetable form but not corn derivatives.
Corn sensitivity can result from contact inhalation
or ingestion: the smell of corn popping or fresh corn on the
cob cooking, body/bath powders, starch on clothing when ironing
or contact on the skin to clothes that have been starched, glue
in shoes or gloves which may contain corn, can all produce various
symptoms of different degrees.
Corn is used to "dust" many containers of cardboard
and plastic surfaces. Try frozen cans of juice instead of
"drinking boxes" or use fresh meat and vegetables wrapped and frozen
and home canned fruit. Corn may also line the milk "cartons"
so bottled milk may be wise. Many medications are also not
corn free so check with the manufacturer before using them.
All corn and corn derivatives must be avoided.
Look for these terms in ingredient listings:
corn syrup and corn syrup solids
Foods containing unspecified vegetable oil or
shortening should not be used, as the source of the oil may be corn.
Baking powder usually contains "starch". To make a corn-free
baking powder, use one of the substitutions below:
Products which may contain corn
- Combine equal parts (by volume) of baking
soda, cream of tartar and potato flour or starch.
- Arrowroot may be substituted equally.
- Combine 4 oz of cream of tartar, 2 oz baking
soda, and 4 oz ground rice - sift together
stamps, stickers, tapes, Gummed Papers: Envelopes, labels, stamps,
Paper Containers: boxes, cups, plates. These three only
when foods have a moist phase in contact with these cartons.
