Peanut butter should be given to babies at a younger age to almost eradicate an epidemic of allergies, scientists say.
A review concluded that 10,000 babies a year will avoid the potentially life-threatening condition if peanuts are introduced from four months instead of the current guidance of six.
Until the last decade, the advice was to avoid them for the first three years, in the belief that eating them as an infant could cause the allergy.
