Food is the fuel of life, we all need it but its not a simple binary function of input output. As we expand our knowledge and science behind our bodies and its requirements our diets can become quite complex. From simple intolerance to full blown allergies. Our nutritional intake can become quite a complicated process.
Allergies and diabetes are the most common concern when it comes to clients diets. the main allergies would be;
⚫ Asprin Intolerance and Salicylates (which covers Salicylates that occur naturally in certain foods)
⚫ Egg Allergy
⚫ Fish and Shellfish Allergy (which covers allergy to crustaceans and molluscs)
⚫ Peanut Allergy (which also covers allergy to lupin)
⚫ Milk Allergy
⚫ Mustard Allergy
⚫ Oral Allergy Syndrome
⚫ Reactions to Wheat (which covers allergy to cereals containing gluten)
⚫ Sesame and Other Seeds (which covers sesame allergy)
⚫ Soya Allergy
⚫ Sulphites and Airway Symptoms (which covers sulphite allergy)
⚫ Tree nut allergy
⚫ Lipid Transfer Protein Allergy
An allergic reaction happens when the immune system reacts to a substance called an allergen. In food allergy this is the protein found in food, which for most people, is harmless. Why the immune system reacts in this way is not fully understood. Food allergies can be divided into two main types which are called IgE mediated (immediate) and non-IgE mediated allergy (delayed).
Allergy testing for IgE mediated (immediate) allergy is done by skin prick testing and/or blood tests which test for specific IgE against a particular allergen(s) e.g. peanut. Oral food challenges (a supervised feed in a hospital or allergy clinic) can help confirm or rule out food allergy. Not all types of food allergy are diagnosed by clinical tests, non IgE (delayed) allergy diagnosis involves a trial of eliminating the suspect food from the diet over a period of time and then reintroduction which should always be guided by a health professional.
