  1. 1. Hippocrates circa 400BC“Let food be your medicineand medicine be your food"
  2. 2. You Are What You Eat
  3. 3. • bloatedness• diarrhea• regurgitation• rashes/flushing
  4. 4. • bloatedness• diarrhea• regurgitation• rashes/flushing
  5. 5. Food = Nutrition• How your body looks, feels, functions depends largely on what you put in it.• The body needs a bare minimum of the right food to function.• 1000 - 1800kcal per day
  6. 6. Lucretius circa 75BC“What is food to one man may be fierce poison to another”
  7. 7. Food Allergy• Immediate onset IgE-mediated, skin test positive, often self-diagnosed• Delayed onset IgG-mediated, skin test negative, rarely self-diagnosed also called: Food Intolerance - UK Food Sensitivity - US
  8. 8. IgE Response to Food• Generally rapid onset after ingestion• Histamine production is rapid• Classic ‘Allergic’ response
  9. 9. IgG Response to Food• Food proteins are recognised as “foreign”• Food specific IgG production and formation of antigen/antibody complexes• Complexes are deposited in tissues and activate complement• Complement and macrophages stimulate Inflammation• Delayed reaction and may last for days
  10. 10. Common Food Intolerances Cows Milk Cheese Nuts Gluten Wheat Egg Soya Yeast
  11. 11. Food Intolerance Test (FIT)• Detect the presence of IgG antibodies to specific foods which may be implicated in food intolerance in symptomatic patients
 • Provide a means to identify the foods most 
 likely to cause a problem, provided the symptoms 
 are food related
  12. 12. Food Intolerance Test (FIT)• ELISA: Enzyme-Linked ImmunoSorbent Assay • a few drops of blood
  13. 13. Food Intolerance Test (FIT)• More than 200 food antigens tested• antibody count >30• ranked according to reactivity• interpretation by physician and/or nutritionist
  14. 14. How does it affect us?• First tissue of contact• Persistent inflammation• Malabsorption
  15. 15. Conditions related to Food IgG• Bloating • Abdominal pain• Migraines • Allergic rhinitis• Insomnia • Palpitations• Weight problems/Obesity • Persistent cough• Anxiety • Pre-menstrual• Skin problems problems • Itchy skin (eczema)• Irritable bowl syndrome• Sinusitis
  16. 16. On endoscopy...• Flattening of the absorptive surface of the intestines (villi) • Normal villi
  17. 17. Malabsorption• Autoimmune diseases• Headaches• Fatigue• Depression• Arthritis and joint pain/stiffness and swelling• Chronic Respiratory symptoms (wheezing or bronchitis)• Abdominal Pain• Bowel Problems (colitis, diarrhoea, constipation)
  18. 18. Malabsorption
