Brain Food – Junk Food may lower IQ.

As parents we are keen to get our children the latest educational toy, send them to the best nurseries and pre-schools and give them the best preparation for school that they can.    A research study conducted by the University of Bristol released today suggests that diet at the age of 3 may have an effect on how intelligent our children are at the age of 8.

The study bases its findings on participants in the Avon Longitudinal Study of Parents and Children (ALSPAC) which tracks 14,000 children born between 1991 and 1992.  It suggests that a diet of predominantly processed,  high fat and sugary foods up to the age of 3 may lower IQ at the age of 8.5. In contrast A diet rich in vitamins and nutrients may do the opposite.  Parents were asked to complete diaries outlining the food and drinks their children consumed at age 3, 4, 7 and 8.5.  IQ was measured at the age of 8.5.  After taking other influential factors into account it was found that children with a predominantly processed diet at the age of 3 were associated with a lower IQ at the age of 8.5, irrespective of whether their diet had improved by that age. Similarly children with a healthy diet at age 3 were associated with higher IQ’s at the age of 8.5.  Diet at the ages of 4 and 7 had no impact on IQ.  Though the findings are modest, the results are in line with previous research which shows that quality of  diet at the age of 3 is related to school performance and behaviour. A possible explanation is that the brain grows at its fastest in the first 3 years of life, therefore good nutrition may lead to optimal brain growth.

So much marketing is aimed at parents and children, making parents feel guilty that they are not buying the child the latest ‘educational’ toy or taking them to classes to improve their language and social skills.  So why not use this as an opportunity to market nutritious food for the youngest children as brain food. Three years isn’t that long a time to limit processed foods and it sets children up with good habits for life.  So maybe next time my 2 year old is nagging for a biscuit or sweet I’ll suggest a healthy alternative –  ‘ Have some special magic food , it will make you clever’.
