Eine Überprüfung von 73 Studien hat zunehmende Beweise dafür hervorgehoben, dass die Ernährung in den ersten Lebensjahren Einfluss darauf haben kann, wie gut sich das Gehirn entwickelt: „Eine schlechtere Ernährung in den ersten Lebensjahren war Jahre später, in der Adoleszenz, mit einer geringeren Intelligenz verbunden.“

> Published in Advances in Nutrition, the study brings together findings from 73 studies — including 48 controlled trials and 25 prospective studies — to examine how diet affects cognitive performance and academic outcomes in young people aged 8 to 19

>To reflect how brain development unfolds over time, the review draws on longitudinal studies exploring links between early-life diet and later cognitive and academic performance. This life-course approach recognises that later abilities build on earlier developmental milestones, allowing the team to examine how early nutrition may shape outcomes years later.

>The researchers assessed long-term evidence on a wide range of nutrients and dietary components, including iron, iodine, choline, vitamin D, polyphenols, fatty acids, grains and multi-nutrient interventions.
