Discovering Hidden Food Allergies
Culprits of hidden food allergies may be hiding in plain sight!
Always read the label and be aware that potentially allergenic foods may be listed under another name in packaged foods. The most common alternative foods that can cause hidden food allergies include:
- wheat flour: durum semolina, farina
- egg white: albumin
- dairy products: Casein, sodium caseinate.
Careful label reading will help you discover what you are eating:
- Cocoa mixes, creamed foods, gravies, and some sauces contain milk.
- Noodles and pasta contain wheat and sometimes eggs.
- Canned soups may contain wheat and dairy fillers.
- Most breads contain wheat and dairy products.
- Margarine usually contains whey.
- Hot dogs, cold cuts, and “nondairy” desserts contain sodium caseinate.
For persons who keep kosher , the word “pareve” on a label means the food does not contain milk or meat. However, recent studies on persons who suffered severe allergic reactions to pareve—labeled foods revealed milk residues.
TRACKING DOWN HIDDEN FOOD ALLERGIES: 3 STEPS
Here’s a three-step method for uncovering what food could be bothering you or your child.
STEP 1: KEEP A FOOD RECORD
Over a four-day period record everything that gets eaten. If you are keeping records for yourself, be sure to include snacks or meals you eat at work or at restaurants. If you’re keeping a food record of what your child eats, do it during a four-day period when your child is home all day so you know exactly what he eats. Don’t make an issue of your child’s food choices during this time or he may sneak (because he craves) the very foods he’s sensitive to. Enlist your child’s cooperation so that together you can keep an accurate record. Also, keep track of any symptoms that you feel may be caused by food allergies.
|Suspected Allergenic Food||Associated Symptoms||Results after Elimination||Notes|
waking up three times a night
|Rash dried up
frequency of diarrhea lessened
|Couldn’t tolerate milk, but yogurt and cheese okay|
STEP 2: TRY AN ELIMINATION DIET
On your list, circle the foods that you most suspect, paying particular attention to the nasty nine:
- dairy products
- egg whites
- tree nuts
- citrus fruits
- food additives
If you have no hunch what you or your child may be allergic to, seek medical help from your doctor or an allergist. Start your elimination diet at a time when there are no outside influences that make the diet impossible to follow, such as during holidays, birthdays, vacations, parties at work, etc. Once you have picked out the most plausible offenders (with or without your doctor’s allergy-testing help), eliminate these for at least ten days (preferably two weeks) and keep track of any reactions. Avoid multiple-ingredient foods during this time, since these may contain multiple potential allergens, making it difficult to isolate the single offender. Focus on objective signs and symptoms; changes in mood or behavior are harder to evaluate.
|NUTRITIP: Play Food Detective
Enlist the help of your child to uncover the hidden food allergies. Make a game out of it. Explain to your child that there’s something in some food that causes her to have a rash and a sore tummy, “Let’s see if we can figure out what it is by playing food detective.” Tell your child that “the rash gives us a clue, so we need to write down all the foods you eat, so we can figure out what causes the rash.”
STEP 3: CHALLENGE YOUR FINDINGS
It’s humanly impossible to be perfectly objective in pinpointing offending foods and what quantities of them cause reactions. Because you don’t want to eliminate nutritious foods from you or your child’s diet without good reason, it’s a good idea to test your findings by reintroducing suspicious foods one at a time, seeing if the concerning signs and symptoms reappear. If they do, that food goes on your no-no list, at least for a few months. Later you can find out whether or not your allergy is dose-related by reintroducing the food, beginning with a small amount once every four days and then increasing both the amount you eat and how often you eat it until your most annoying signs reappear. This threshold effect is especially characteristic of dairy allergies . Some people can’t even drink one glass of milk a day, but they can tolerate a cup of yogurt every other day.

Allergens may appear in the most unlikely places, so get used to reading the ingredient list. A candy bar, for example, may contain corn, dairy, gluten, soy, colorings and additives – all of which are potential food allergens.
THE QUICK-DETECTION METHOD FOR ZEROING IN ON HIDDEN FOOD ALLERGIES
Use this method if you are a well-disciplined adult. It is more difficult to use successfully on a child.
1. Eliminate the possible suspect foods, beginning with the nasty nine, for a period of at least a week or ten days. During this time, eat only the least allergenic foods, such as: fresh fruits (except berries and citrus), avocados, rice, barley, millet, poultry, and lamb. All the foods, if possible, should be organic and free of additives, dyes, and colorings.
2. Reintroduce one new food each week to see if symptoms reappear.
How much time, energy, and expense you are willing to spend on tracking down food allergies depends upon how much they bother you or your child, and whether your symptoms are getting better or worse. The good news is that food allergies are one medical problem where you can truly say that children will “grow out of it.” Most food allergies in children either become less severe or entirely disappear as they get older. Of course, if the child is miserable and is making everyone else miserable, too, you may not want to wait for him to grow older to do something about them.
|NUTRITIP: Sweetener Allergy
Once upon a time we physicians were all taught that the body can only be allergic to proteins. But once again, others’ observations are at odds with scientists. Many wise parents report that their infant or child goes berserk after high doses of sweeteners, such as corn syrup. Even the purists among allergists are beginning to believe in the concept of brain allergy, meaning that the chemicals a person eats can have a profound effect on biochemistry — thinking, feeling, and behaving. Corn syrup is a common sweetener in processed foods, baby formulas, and sodas. The fact that corn syrup has become so prevalent in the American diet may account for an increasing number of allergies to it. As one mother who successfully tracked down her infant’s gassiness, diarrhea, night-waking and fussy behavior to corn syrup wrote us, “I feel that there is a corn syrup conspiracy going on in our country.”
