Food Allergies Q & A

What are food allergies?


Food allergies are an overreaction by your body to food that is not typically harmful. When exposed to a particular food, your immune system mistakenly goes on the defense, triggering a variety of uncomfortable or painful symptoms.

Some of the most common food that triggers an allergic reaction include:

  • Soy
  • Milk
  • Nuts
  • Eggs
  • Wheat
  • Shellfish

You can also have an intolerance to certain foods, which causes, for example, stomach cramps and gas after consuming them. However, your reaction to a food intolerance doesn’t involve your immune system.

What are the symptoms of food allergies?

Your allergic reaction to certain food can cause a wide variety of symptoms that range from mild to life-threatening. Some of the most common symptoms of food allergies include:

  • Diarrhea
  • Vomiting
  • Skin rash
  • Mouth tingling

Those with a life-threatening reaction to a food, known as anaphylaxis, may experience sudden throat tightness and difficulties breathing. They may also lose consciousness. This type of reaction requires emergency treatment at the nearest hospital or by calling 911.

How are food allergies diagnosed?

By understanding your food allergies, you can prevent serious health complications. During an evaluation, your Essential Nutrition provider reviews your medical history and discusses the reaction you have to a specific food.

The team prefers using a dietary approach first to identify the potential triggers of your food-related allergies, as it is considered the gold standard in the field. 

It also allows patients to save money, and the results are often just as good, if not better than using food sensitivity testing. They may request you start an elimination diet, removing suspect allergens from your diet and slowly adding them back in to see how your body reacts. 

The practice utilizes tools and procedures that don't come at an additional cost. As a last resort, they offer blood testing using the Mediator Release Test (MRT®), a cell-based blood test. MRT measures your inflammatory responses to food, and based on your results, identifies your best foods and creates a custom LEAP (Lifestyle Eating and Performance) diet plan.

Based on the results of your diet changes and blood test (if needed), the team at Essential Nutrition can recommend the right treatment plan.

How are food allergies treated?

The primary goal in treating food allergies is to avoid the triggers that cause an allergic reaction. Your Essential Nutrition provider works closely with you on a diet plan that restricts certain foods. They can also teach you how to read food labels to identify ingredients that may cause an allergic reaction.
