While the association between nutrition and general health is now increasingly accepted in the medical community, also thanks to movements as Nutritank, it is only recently that the effects of nutrition on the brain have started to be investigated.
Among other mechanisms, one way poor diet impacts brain function is by inducing a low-grade chronic inflammation state. In the brain, the hippocampus is especially sensitive to inflammation; in fact, hippocampal dependent abilities (e.g. memory) are severely impacted by poor nutritional status.
Using functional magnetic resonance
imaging (fMRI, see picture below) we are investigating how children’s diet and
BMI relates to their abilities to orient
hippocampal-dependent ability, and the way they use their brain to
do so. We will also be relating
these results to participants’ inflammation levels to
see if inflammation mediate s the
relationship between dietary quality, BMI and cognitive abilities.
The fMRI machine used for our experiment- Donders Centre for Cognitive Neuroimaging (Radboud University, Nijmegen, the Netherlands).
We expect that our results will support the importance of a healthy
(Mediterranean-like) diet for cognitive abilities and brain function
in children. With obesity and poor dietary quality being on the rise, studies
investigating the relationship between nutrition and cognition are extremely
important to start informing new policy changes, such as in education and
We hope that our results, together with previous literature, will encourage an increased attention to the pivotal role of diet in impacting children’s brain health. Medical professionals in general, and
in particular, should receive formal training in order to be able to support
parents to make informed nutritional choices for their kids, in order to
promote a healthy development of their most important asset , their
