Intolerances/Sensitivities to foods + food additives + food chemicals + environmental chemicals + herbs/dietary supplements + moulds can cause a wide range of symptoms and disorders. The ALCAT® diagnostic system detects changes in the size and number of leucocytes (i.e. immune cells) in response to exposure to the offending foods, chemicals, additives, herbs and moulds.
Adverse reactions to foods can cause both mild and severe health problems in a subset of the population. Immediate food allergies are known to affect 4% of the general population, whereas general adverse reactions to food may affect a much higher proportion (>20%). The symptoms caused by the food reactions can be as mild as bloating but as severe as anaphylaxis. Conditions which may be caused or exacerbated by adverse food reactions include asthma, arthritis, irritable bowel syndrome (IBS), migraine, otitis media and skin rashes. A wide variety of more non-specific symptoms can be attributed to food sensitivities such as fatigue, headaches, and difficulty losing weight, food addictions and trouble concentrating.
