Struggling With Food Allergies? Read This!

Food allergies may have been rare in the past, but in recent times, with our changing lifestyles and food habits, food allergies are on the rise. A survey conducted in a single state in the country showed that more than 26% of the population had food allergies.

At present, there is no cure for allergies, except avoiding the foods that you are allergic to. However, some useful tips can potentially prevent symptoms of allergic reactions. You should also keep away from food allergens and learn to quickly manage food allergies when they occur.

Tips To Prevent Symptoms of Food Allergies

Allergies are immune responses set off and histamines, i.e., inflammatory mediators produced to fight what it assumes is an attack on the body. Most people confuse intolerance with allergy. Allergy is an immune response whereas intolerance is not an immune response.

Intolerance is when there is a lack of enzymes in your digestive system to break down a particular food. For instance, if you are lactose intolerant, you can have some amount of milk or milk products. When you have the same food in large quantities it can create problems.

In the case of food allergies, abnormal response is triggered for a particular food and manifests in the form of sneezing, nasal congestion, or anaphylaxis. Anaphylaxis is an immune response that sends the body into a state of shock by impairing breathing.

Here are a few tips to prevent food allergies

Avoid Common Causes of Allergies –– Cross-Contact & Cross-Reactivity

Avoiding Cross-Contact

Cross-contact between allergic and non-allergic foods happens inadvertently sometimes. You might replace allergic food with non-allergic food from a recipe to give it a different name and look. This will be a direct contact. In the case of indirect contact, you will be using the same vessel to prepare both non-allergic food and allergic food without cleaning the utensil after one preparation.

Follow these simple steps to avoid cross-contact and stay away from food allergies:

  • Maintain a separate cooking area, if you’re sharing your kitchen.
  • Clean all your vessels, cooking apparatus’, stove tops, and cooking platforms thoroughly with cleaning liquids.
  • Get rid of all the food items that you’re allergic to.
  • Wash your hands thoroughly if you have handled food allergens.
  • If you are cooking a variety of foods, then cook non-allergic foods first.
  • Cover non-allergic foods to avoid cross-contact with allergic foods.
  • Clean the cooking counter thoroughly after cooking every meal.
  • Do not share food

Avoiding Cross-Reactivity

When proteins in two different foods are similar, your immune system is unable to differentiate between them and may set off an immune response. This results in an allergic reaction, triggered by cross-reactivity. People generally avoid eating any item from the same food group when allergic to any one food type in a food group. For example, if you’re allergic to cheese, you can avoid eating all dairy products.

If you want to try food from the same food group you’re allergic to, take an allergy test or food intolerance test before consumption.

Examine Food Labels For Allergens

Reading the food label is a precaution to keep away from food allergens to people who are prone to food allergies. But the food labels confuse the consumer which may make them more susceptible to food allergies. If the labels say ‘ may contain’ or ‘manufactured on shared equipment’, it is worth keeping away from such products to avoid allergic reactions.
