United States: Research published in Nature Metabolism shows pregnant mothers can greatly affect their offspring’s susceptibility to developing ADHD and autism by what she eats during pregnancy. Research indicates that diets containing high amounts of fat and sugar and processed food elements found in Western dietary patterns raise the risk of developmental disorders in youngsters, as reported by HealthDay.
Western Diet Increases Risk of Developmental Disorders
The researchers at the University of Copenhagen found that female patients who consumed a Western eating pattern consisting of high dietary fat content alongside sugar and processed foods together with limited fresh seafood did not secure enough vegetables or fruits during pregnancy:
- 122% higher risk of autism in their children
- 66% higher risk of ADHD
The study suggests that small dietary changes—such as reducing processed foods and increasing nutrient-dense options—may help lower these risks.
Large-Scale Study Confirms Diet’s Role in Child Development
The study examined eating habits of more than 500 Norwegian mothers who had children affected by ADHD or autism at age 10. They conducted additional research with 60,000 mother-child pairs to verify the established relationship between maternal nutrition during pregnancy and child brain development.
The most significant associations were found in the first and second trimesters, indicating that early brain development is particularly sensitive to maternal diet.
Metabolites in Maternal Blood Explain Diet-Neurodevelopment Link
The researchers detected 43 distinct metabolites in maternal blood from Western diet consumption where fifteen specific metabolites corresponded to higher ADHD prevalence rates.
Dr. David Horner who led the study explained that these metabolites serve critical functions in brain developmental inflammations and oxidative stress.
Current Pregnancy Nutrition Guidelines May Need Revision
The research results question the existing pregnancy food guidance that utilizes non-pregnant guidelines.
“We know that nutritional demands increase during pregnancy, and our study highlights how crucial dietary composition is for fetal development,” said Horner. “While the Nordic diet is often considered healthy, many pregnant women still follow eating patterns that could be optimized to better support their child’s development.”
Takeaway
By limiting high-fat, high-sugar, and processed foods while increasing nutrient-dense options like fish, fruits, and vegetables, expectant mothers may help lower their child’s risk of ADHD and autism, as reported by HealthDay.
