Food Intolerance vs. Allergies

A food intolerance often affects only the digestive system and causes less serious symptoms, usually gastrointestinal symptoms, nausea, vomiting, or dehydration. In contrast, a true food allergy affects the immune system, and even small amounts of the offending food can trigger a range of symptoms, which can be severe or life-threatening.

Gluten Intolerance

Gluten is an elastic, stretchy protein commonly found in grains and products with grains, especially wheat, rye, barley, and sometimes oats. People with gluten intolerance have difficulty digesting and processing it. Gluten lacks any general, essential nutrients.

Gluten intolerance is NOT the same as coeliac disease, gluten ataxia, or a wheat allergy. The reactions are similar but much quicker and simply gastrointestinal in nature.

Coeliac disease is when gluten triggers an autoimmune reaction that causes cell damage to the small intestine, which in turn can cause diarrhoea, fatigue, weight loss, bloating, anaemia and other problems and lead to serious complications. It is a slow process that is not felt immediately.

Gluten ataxia is officially an autoimmune disorder, and affects certain nerve tissues and causes problems with muscle control and voluntary muscle movement.

Wheat allergy, like other food allergies, is the result of the immune system mistaking gluten or some other protein found in wheat as a disease-causing agent like a a virus or bacterium. The immune system then creates an antibody to the protein and a response that may result in congestion, breathing difficulties and other symptoms.
