The Spanish Society of Pediatric Allergy and Clinical Immunology (SEICAP) has expressed its support for these recommendations, in a statement, which advises consulting a pediatric allergy centers if you suspect your child may be allergic.

Foods such as cow's milk, eggs, nuts, soy or gluten can be introduced at children aged six months, postponing the fact is no longer associated with the onset of eczema or wheezing ( beeps when breathing), the study said.

The research, conducted by the University Hospital Rotterdam (Netherlands), was conducted with 6,905 children from birth to four years, between April 2002 and January 2006.

These children have started to introduce between six and twelve months, foods such as cow's milk, eggs, nuts, soy and gluten and found that there was no relation to the development of eczema or wheezing, according to SEICAP.

The results were that 31% of children had wheeze at two years and 14% at three to four years.

These percentages are common, as it is shown that one in three children will wheeze at two years, caused by viral infections, and allergic asthma usually occurs towards the three or four years, according to Dr. Ana Maria Plaza, coordinator of the working group of food allergy SEICAP.

Another common reaction was eczema, which accounted for 38% of children at two years, 20% at three and 18% at four.

According to the authors, this demonstrates that the late introduction of foods after six months of age is not associated with fewer allergic diseases at two, three four years.
