Allergy & Intolerance to Gluten and Wheat

What is wheat?

Wheat is a popular grain farmed throughout the world for use in various foods such as bread, pasta and various baked goods. It has been a staple of many cultures’ diets for several thousand years, although the grain has been bred and modified over this time to improve yield, so some might consider.

What is gluten?

Gluten is a protein found in certain grains such as wheat, barley and rye. Those who have a gluten intolerance should avoid all three of these grains and any other foods which may also contain gluten.


What does an allergy or intolerance to Gluten or Wheat mean?

It is a common assumption that wheat is thought of as the primary grain which people have an allergy or intolerance to. Non-coeliac gluten sensitivity has become better understood in recent years, and we’re just beginning to determine how widespread it really is [1, 2].

Although Wheat is often the cause of a food allergy or intolerance, there are other grains which can cause an allergy or intolerance, including Barley and the lesser-known component Gluten. Furthermore, Rice and Oats can also cause your body to react, and all of these items are accountable for various individual food allergies & intolerances throughout the UK.


What are the Symptoms?

Common symptoms of Wheat or Gluten intolerance include;

  • Bloating
  • weight gain
  • fatigue
  • skin problems (such as eczema, rashes or even acne)
  • migraines


Common allergy symptoms of wheat or gluten include;

  • Sneezing
  • Itchy, red or watery eyes
  • Swollen lips, tongue, eyes or face
  • Stomach pain
  • Vomiting
  • Diarrhoea
  • Wheezing, difficulty breathing or a tight chest
  • Anaphylaxis (Anaphylactic shock)

It’s important to remember is that even a mild food allergy or intolerance to grains and staples may affect the way a person is able to live their life. Even more importantly, these foods are one of the most common inclusions in any person’s diet, meaning the offending food will be difficult to detect, and thus avoid. An allergy or intolerance can help in this regard, but you should always be careful when picking up produce from the shops and read the ingredients carefully.

Foods to Avoid

Foods containing gluten or wheat include;

  • Pasta
  • Baked Goods
  • Cake

  • Gluten-Free Oats (Oats don’t usually contain gluten, but may be processed in an environment with gluten, so potential for cross contamination should be considered)
  • Potatoes
  • Rice
  • Corn
  • Fresh Vegetables


Test for food allergies & intolerances to wheat and gluten

Testing for intolerances to wheat and gluten

Testing for wheat or gluten food intolerance can be conducted through a simple home-to-lab blood sample test. A small blood sample can conveniently be taken at home and then sent to a lab for analysis. These tests analyse the blood’s IgG (Immunoglobin G) levels for an intolerance to various food items and use standardised benchmarks to make these measurements [3]

Testing for allergies to wheat and gluten

An allergy test can be conducted using the same blood sample but looking for a different strand of immunoglobin (IgE). This sample can also be taken at home and sent to a lab for testing, with results then sent back to you, highlighting any potential allergies.

At Test Your Intolerance, our expert team have devised a scientifically validated food allergy & intolerance blood testing kit, highlighting what foods your body is intolerant to, including wheat or gluten. Examining hundreds of food and non-food items, the team aim to provide you with all the results you need. This can be completed easily at home by sending us a sample of your blood in the post.

We also offer bioresonance hair testing which allows us to assess your sensitivities against up to 800 items using just a few strands of hair.
