Difference Between Wheat Intolerance and Wheat Allergy

Wheat Intolerance: Wheat intolerance is a delayed onset reaction caused by gluten (contained in wheat, rye barley and oats and other grains). It affects 1 in 7 people.

Wheat Allergy: Wheat allergy is the severe sudden onset allergic reaction to a certain protein component of wheat. It affects less than 0.5% of the population.

When most people speak of wheat allergy they are really referring to wheat or gluten intolerance.

Symptoms of Wheat Allergy and Wheat Intolerance

Wheat allergy causes the same sudden onset symptoms caused by other allergens - coughing, asthma, nausea, vomiting, diarrhea, hives, rashes etc.

However the symptoms for wheat intolerance (Gluten intolerance) are much more varied and usually have a delayed onset - up to 2 or 3 days later. This is why they are traditionally difficult for doctors to diagnose. They can be:

  • Gastro-intestinal: stomach bloating & pain, diarrhea, flatulence, constipation etc.
  • Neurological: headache, memory loss, behavioural difficulties, depression
  • Immune: poor resistance to infection, mouth ulcers
  • Inflammatory disease: arthritis, colitis, thyroiditis etc.
  • Skin rashes, eczema, psoriasis, itching flaky skin
  • General: food cravings, tiredness, chronic fatigue, unwell feeling
