Food Intolerance Symptoms

Below is a list of symptoms that can be caused by intolerance to salicylates, amines, glutamates and additives.

A few notes:

  • Different individuals experience:
    • different types of symptoms
    • different numbers of symptoms
    • different strengths of symptoms
  • The same individual may experience different symptoms and sensitivity levels:
    • over the course of a lifetime
    • to different food chemicals
    • to the same food chemicals depending on:
      • quantity
      • hormones
      • blood sugar levels
      • nutritional status
      • the presence of other food chemicals
      • other extraneous factors
  • Food chemical intolerance:
    • tends to run in families
    • can come from nowhere
    • is often present from birth
    • can appear suddenly in childhood or adulthood
    • can appear after a physical trauma like an illness, a hospital stay, a change in diet, the use of pharmacological or recreational drugs including aspirin, or the ingestion of additives or toxins
    • can appear after a strong emotional trauma like the loss of a job or a home, a divorce, or a bereavement

Some of these symptoms can be caused by other, unrelated factors. They are not always caused by this set of food chemicals, or even always by food. Sometimes some of these symptoms can be caused by nutritional deficiencies, infections, allergies, other substances in food, or can be caused by physical or emotional stressors. Sometimes they can be caused by an underlying illness, like jaundice, anaemia, thyroid disorders, liver or kidney disease or damage, or by genetics.

It is rare that someone with food chemical intolerances experiences ALL of these symptoms. The symptoms should be assessed as a whole and used as guidance to determine if there might be a problem and how great the problem is. The more symptoms, and the stronger the symptoms, the more important food chemicals may be to the health problems of the individual. On this basis the individual should assess whether they should embark on the elimination diet trial.
