Soy allergy what to avoid

Food allergies are divided into 3 types, depending on symptoms and when they occur.

  1. non-IgE-mediated food allergy – these allergic reactions aren’t caused by immunoglobulin E, but by other cells in the immune system. This type of allergy is often hard to diagnose as symptoms take much longer to develop (up to several hours).
  2. IgE-mediated food allergy – the most common type, triggered by the immune system producing an antibody called immunoglobulin E (IgE).

    Symptoms occur a few seconds or minutes after eating. There’s a greater risk of anaphylaxis with this type of allergy.

  3. mixed IgE and non-IgE-mediated food allergies – some people may experience symptoms from both types.

Who’s affected?

Most food allergies affect younger children under the age of 3.

Most children who own food allergies to milk, eggs, soya and wheat in early life will grow out of it by the time they start school.

Peanut and tree nut allergies are generally more endless lasting.

Food allergies that develop during adulthood, or persist into adulthood, are likely to be lifelong allergies.

For reasons that are unclear, rates of food allergies own risen sharply in the final 20 years.

However, deaths from anaphylaxis-related food reactions are now rare.


In the most serious cases, a person has a severe allergic reaction (anaphylaxis), which can be life threatening.

Call 999 if you ponder someone has the symptoms of anaphylaxis, such as:

  1. trouble swallowing or speaking
  2. breathing difficulties
  3. feeling dizzy or faint

Ask for an ambulance and tell the operator you ponder the person is having a severe allergic reaction.

What causes food allergies?

Food allergies happen when the immune system – the body’s defence against infection – mistakenly treats proteins found in food as a threat.

As a result, a number of chemicals are released. It’s these chemicals that cause the symptoms of an allergic reaction.

Almost any food can cause an allergic reaction, but there are certain foods that are responsible for most food allergies.

Foods that most commonly cause an allergic reaction are:

  1. tree nuts
  2. fish
  3. milk
  4. shellfish
  5. peanuts
  6. eggs
  7. some fruit and vegetables

12 Tips for Avoiding Cross-Contact of Food Allergens

Foods that cause allergic reactions are called allergens.

Even a tiny quantity of an allergen can cause a reaction. Allergic reactions generally happen after your kid eats a food that she or he is allergic to.

Avoid Contaminating Your Food Supply

If you hold both «safe» and «unsafe» foods in your household, you need to take steps prevent cross-contact:

  1. Utensils – Do not permit allergen-covered utensils to touch your «safe» foods. For example, if a knife used on butter gets inserted into a jar of jam, the jam is no longer safe for a dairy-allergic individual to eat. If you spread butter on wheat bread toast and then dip your knife into the butter again, the butter will now contain traces of wheat.
  2. Hands – Teach everyone to wash their hands with soap and water before touching safe foods.

    Their hands could own allergens on them and they could make a safe food become unsafe.

  3. Countertops and other surfaces – Teach everyone to clean every surfaces after preparing food and to clean countertops before preparing food. Countertops could own traces of allergens on them. Food prepared on an unclean countertop can result in cross contact with allergens.

Avoid Getting Allergenic Residue Every Over the House

If you permit food allergens in your home, you need to prevent allergen residue from getting every over the home.

Teach every members of your household to always wash their hands with soap and water immediately after touching or eating allergens. Consider confining every food consumption to your kitchen and dining areas. Otherwise, crumbs and traces will get onto your carpets, furniture, toys and other surfaces.

Label Foods in Your Home as «Safe» or «Not Safe»

To ensure everyone (including your children, visitors, babysitters, etc.) can determine which foods in your home are «safe», it can be helpful to label the food in your pantry, refrigerator and freezer.

A convenient way to do this is to use red and green circle-shaped stickers. You can purchase these types of stickers or make your own. The red stickers are for the unsafe foods and the green are for the safe foods (i.e., «red» means «stop» and «green» means «go»). Apply these stickers to every food item in your house.

Take Precautions When Cooking

Take steps to avoid cross-contact with allergens during the cooking or serving process:

  1. Do not use the same utensils to prepare allergenic and non-allergenic dishes.
  2. Place utensils, plates and cutting boards  directly into the sink or the dishwasher immediately after use.

    Teach your family that soiled items in the sink or dishwasher are not safe to use until they own been properly washed.

  3. If you are preparing both “safe” and “unsafe” food for the same meal, prepare the safe meal first.
  4. If you use a barbecue, be certain to fully clean the grill before cooking for your kid. Consider using foil or a clean grill pan to prepare foods for your child.

Don’t Forget Your Guests

If your friends own infants, you may need to take precautions to avoid spit up on your carpets or furniture. The food, formula, or breast milk that is spit up is likely to be allergenic, and will get on surfaces your kid may touch. Set below a clean blanket for babies to protect carpet or furniture.

Others, especially those whose children own numerous food allergies, do not make this choice. If you select to permit allergens in your home, you run the risk that those foods will «contaminate» your home and your safe foods. This is known as cross contact.

Cross-contact occurs when a food allergen comes in contact with food or an item not intended to contain that allergen. Little traces of allergens can cause allergic reactions.

There are several precautions you should take to avoid food mix-ups and accidental cross-contact.

Avoid Sippy Cup Mix-Ups

If your toddler is allergic to milk, purchase a «special» sippy cup to use both at home and away from home.

This cup is never used for anyone else. Put your child’s name on it. Once you put the lid on the average sippy cup you cannot see the contents. Having a special cup that is always used ensures that your kid doesn’t grab the incorrect cup by mistake.

Avoid Pantry Mix-Ups

If you own both «safe» and «unsafe» versions of similar items (like soy milk and cow’s milk) in your home, do not store these products next to each other. Designate specific shelves or cabinets for storing the «safe» foods. Avoid purchasing items that glance similar to each other.

Take Care to Wash Dishes

Wash pans, utensils and dishes in boiling, sudsy water before using them to prepare food for someone with food allergies.

It is best to rinse off dirty dishes and utensils before loading them into your dishwasher. This prevents stray bits of dried allergens from sticking to your clean dishes.
