Clinical Trial Summary

Allergy prevalence is increasing steadily with some describing as the "epidemic of the twenty-first century". Maternal diet during pregnancy has been linked to offspring allergy risk, so it represents a potential target for allergy prevention. The Mediterranean Diet (MD) is considered one of the healthiest dietary models which exerts regulatory effects on immune system, due to the synergistic and interactive combinations of nutrients. We aim to study the effects of MD in pregnancy on the onset of allergic diseases at 2 years of age in the offspring.
