Non Food Problems
Adverse reactions and symptoms can be caused by sensitivities to many substances that are not food. The term MCS (Multiple Chemical Sensitivities) refers to a condition in which an individual experiences unwanted reactions, at times extremely serious ones, to a number of chemicals in the environment including those found in perfumes, plastics, carpets, cleaning agents, and paint. It is possible to be sensitive to any chemical.
Reactions to non-food items are also a problem for many people with a food sensitivity as the problem food may be used in the manufacturing process.
Sadly in respect of Salicylate the problem can be quite serious as salicylate, in various forms, is found in medicines, ointments, toothpaste, cleaning products, air fresheners, fabric conditioners, perfumes, essential oils and many many more items.
More information can be found in the Salicylate Handbook.
