Effects of the Mediterranean Diet During Pregnancy on the Onset of Allergies in the Offspring (PREMEDI)
April 14, 2023 updated by: Roberto Berni Canani, MD, PhD, Federico II University
Effects of the Mediterranean Diet During Pregnancy on the Onset of Allergies in the Offspring: a Multi-center Randomised-controlled Trial (the PREMEDI Project)
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.
