Objectives
Narrative objectives1
Aim1: By conducting randomized controlled trial, we aim to clarify whether food allergy of children by 2 years of age is preventable by restricting maternal intake of processed meat and fish, and others: nuts, ice-cream, butter or buttered food, e.g., croissant, biscuits, cookies, pastry, etc. during first month after birth.
Aim 2: By exploring reactions of cord blood to food allergens and others in vitro, we aim to study mechanisms of sensitization to certain food and of food allergy prevention in the ABC trial during perinatal period.
Aim 3: We aim to study effects of intervention on gut microbiota of infants at birth and during infancy by means of 16s metagenome analyses and components derived from breast milk. Moreover, we aim to investigate whether these gut microbiota and breast milk components are further associating with food allergy.
Aim 4. We aim to examine whether these gut microbiota and breast milk components including intervention in this trial are associating with developmental disorder, i.e., autism spectrum disorder (ASD), attention-deficit hyperactivity disorder (ADHD) and others.
Aim 5: By conducting randomized controlled trial, we aim to clarify whether autism spectrum disorder (ASD) and/or attention deficit hyperactivity disorder (ADHD) of children by 2 to 3 years of age is preventable by restricting maternal intake of processed meat and fish, and others: nuts, ice-cream, butter or buttered food, e.g., croissant, biscuits, cookies, pastry, etc. during first month after birth.
