Your nutritional well-being just a few steps away

Food intolerance is when the body has an adverse reaction to the consumption of certain foods, additives or preservatives which causes the immune system to produce antibodies to deal with certain proteins contained in these food substances.  

A proportion of the population (1-3 % of adults and 4-6 % of children) suffer from adverse health consequences as the result of consuming certain foods or food ingredients.

Food allergies and intolerances can have similar symptoms, but they are different medical conditions.


The main symptoms which appear after eating one or more foods are:

  • Migraine, headache, fatigue.
  • Depression, anxiety, hyperactivity.
  • Muscular pain, joint pain.
  • Vomiting, sickness, stomach ulcers, duodenal ulcers.
