The role of prebiotics in the prevention of allergies in infancy

Food allergy in childhood has been on the increase over the last decade, with the prevalence in the UK being between 6-8%. Several studies have focused on possible preventive measures and strategies: avoidance of food allergens during pregnancy, breastfeeding and weaning; and the addition of omega-3-fatty acids, antioxidants and pre- and probiotics. The gastrointestinal tract is one of the first lines of immunological defence and must be healthy to maintain an effective immune response. The concept of prebiotics, normally found in breast milk, has been introduced as a measure to improve gut health. Recent research has focussed on the use of prebiotics in the prevention of allergies in infancy.
