'The results of this long-term study are exciting and suggest that, in principle, it is possible to protect high risk children from developing asthma by minimising their exposure to allergens. It is one of the most rigorous and comprehensive asthma research studies ever undertaken, which included altering the child's home environment, their mother's diet during pregnancy and the child's diet until the age of one.

'However, although this news is very encouraging, it's important to point out that the methods used were very intensive and the families needed substantial guidance and support in order to significantly reduce their child's allergen exposure. As this approach is only likely to be worthwhile in families with a strong history of severe asthma and other allergic conditions, there remains a need for improved allergy services across the UK.'
