Quick Overview:

A Spanish study published in May 2019 found that a maternal diet rich in nuts during the first trimester of pregnancy is linked to improved cognitive outcomes in children, including better attention capacity, cognitive function, and long-term memory. Conducted by the INMA project across four regions of Spain — Sabadell (Barcelona), Valencia, Guipuzcoa, and Asturias — the research tracked approximately 2,200 mother-and-child pairs enrolled in dietary cohorts. The findings suggest that the first three months of pregnancy may represent a critical window during which nut consumption can meaningfully shape fetal neurodevelopment. Expectant mothers looking to support their child's brain health may have a straightforward, evidence-backed dietary intervention available to them from the earliest stage of pregnancy.

What Our Patients Say

Gráinne Macken

This is my second visit to Merrion Fetal, I was very pleased on both occasions. Lovely quiet waiting room, appointment was on time. The 20-week scan is very detailed we enjoyed watching our baby on the large TV screen. We got some beautiful photos. The nurse was very pleasant and talked us through all the measurements and anatomy. I would highly recommend this scanning clinic.”

Áine Gibney

I had the best experience at the Merrion Fetal Health clinic for my 20-week big scan. The staff were so friendly and so nice and the lovely lady who did my ultrasound scan was amazing. She was so thoroughgoing to absolutely everything and gave me such reassurance on how my baby was growing and developing. I would recommend any Mother to be to attend here if you are looking for a comfortable, reassuring and super pleasant experience.”

Linda O'Sullivan

Highly recommend! We had an early scan due to a little scare at the start of pregnancy and then another at 12 weeks to make sure all was good again. Helen who was scanning on both days was fantastic. We felt totally relaxed and un-rushed while she took her time finding the best angle of baby to get us the clearest pictures as keepsakes all while making sure everything was perfect with baby. She reassured us throughout and I can honestly say it was the best money we ever spent getting both scans done.

Please let Helen know we are 18 weeks now and flying along Highly recommend!
