About this test

Food sensitivities refer to problems with processing or digesting certain foods. Common sources of food sensitivities are:

  • Dairy/lactose
  • Gluten (proteins found in grains like wheat, barley, and rye)
  • Eggs
  • Caffeine (a natural stimulant found in coffee, tea, soda, and energy drinks as well as chocolate)
  • Salicylates (natural chemicals that are found in a wide range of foods, including fruits, vegetables, teas, coffee, spices, nuts, and honey; also used as a food preservative)
  • Amines (natural chemicals commonly found in fermented foods)
  • FODMAPs (fermentable oligo-, di-, mono-saccharides, and polyols — specific carbohydrates and sugars that can draw water into the digestive tract)
  • Sulfites (a chemical found naturally in grapes and aged cheeses; also used as a preservative in food, drinks, and medications)
  • Aspartame (an artificial sweetener)
  • Monosodium glutamate (MSG — a flavor-enhancing food additive)
  • Yeast 
  • Food coloring

Symptoms of food intolerances can vary, but the most common symptoms involve the digestive system. In some cases, symptoms of food sensitivities may affect the skin and respiratory system. Unlike food allergies, food sensitivities don’t cause life-threatening symptoms, but they can cause discomfort that typically starts within hours of eating and can last for days. 

The best way to deal with food sensitivities is to cut the offending foods from your diet. This test can help you prioritize which foods to try eliminating. This test may be useful if you experience any of these common symptoms of food intolerance:

  • Diarrhea
  • Bloating
  • Nausea and stomach pain
  • Reflux
  • Headaches
  • Fatigue
  • Runny nose
  • Rashes or skin flushing

 

Please note: take care when eliminating foods from your diet. A restrictive diet can lead to nutrient deficiencies and malnutrition. If you plan to eliminate foods for longer than a couple of weeks, it is recommended that you contact a nutritionist.

The Food Sensitivity test measures a specific type of immune response, IgG antibodies, that may be related to how well you process and digest food. This is different than an allergy, which is caused by IgE antibodies.

This test measures your body's immune response to 108 foods.
