Prevalence of food hypersensitivity

Various aspects of 'food hypersensitivity' and a report on population studies to assess its prevalence for different foods and population groups are discussed. Food hypersensitivity can be divided into food allergy and non-allergic food hypersensitivity (FHS). Correct diagnosis of FHS is important to ensure individuals with FHS are appropriately managed and treated. Self-reported FHS and proven FHS differs significantly across multiple countries and reasons for these differences are largely due to cultural differences, diet and exposure to allergy. The prevalence of FHS in adults is between 1.5-3.5% and 2-8% in children.
