Food allergies have been on the rise in recent years and are currently estimated to affect up to eight percent of children worldwide, according to the World Allergy Organization. "For decades we have been focusing on avoidance and that didn't seem to work," says Gideon Lack, Professor of Pediatric allergy at Kings College London. The theory behind this is that exposure enables a child's immune system to learn to recognize, and tolerate, the allergens rather than react to them, as it does with other organs and cells in the body. The study recruited more than 1300 infants aged 3 months old, half of whom were given up to 4 grams of each of the six food proteins, weekly. ...significant reductions were seen including a 100 percent protection against peanuts allergy and a 75 percent reduction against egg allergy, according to Lack. For now, the team do not recommend using the approach outside of a supervised trial, and advise parents to continue World Health Organization (WHO) recommendations in terms of food provision to infants, such as breast feeding, until further evidence is available.?
