Diet during pregnancy and early life affects children’s behaviour and intelligence
The statement “you are what you eat” is significant for the development of optimum mental performance in children as evidence is accumulating to show that nutrition pre-birth and in early life “programmes” long term health, well being, brain development and mental performance and that certain nutrients are important to this process.
Researchers from the NUTRIMENTHE project have addressed this in a five-year study involving hundreds of European families with young children. Researchers looked at the effect of, B-vitamins, folic acid, breast milk versus formula milk, iron, iodine and omega-3 fatty acids, on the cognitive, emotional and behavioural development of children from before birth to age nine.
The study has found that folic acid, which is recommended in some European countries, to be taken by women during the first three months of pregnancy, can reduce the likelihood of behavioural problems during early childhood. Eating oily fish is also very beneficial, not only for the omega-3 fatty acids they which are ‘building blocks’ for brain cells, but also for the iodine content which has a positive effect on reading ability in children when measured at age nine.
A long-term study was needed as explained by Professor Cristina Campoy, who led the project “Short term studies seem unable to detect the real influence of nutrition in early life”, explained Prof Cristina Campoy, “NUTRIMENTHE was designed to be a long-term study, as the brain takes a long time to mature, and early deficiencies may have far-reaching effects. So, early nutrition is most important.”
Many other factors can affect mental performance in children including; the parent’s educational level, socio-economic status of the parents, age of the parents and, as discovered by NUTRIMENTHE, the genetic background of the mother and child. This can influence how certain nutrients are processed and transferred during pregnancy and breastfeeding and in turn, affect mental performance.
In giving advice to parents, Cristina Campoy explained, “it is important to try to have good nutrition during pregnancy and in the early life of the child and to include breastfeeding if possible, as such ‘good nutrition’ can have a positive effect on mental performance later in childhood.” She went on to explain, “however, in the case of genetics, future studies should include research on genetic variation in mothers and children so that the optimum advice can be given. This area is relatively new and will be challenging!”
