children whose diet at the tender age of three years mainly consists of fatty, sugary and refined foods, according to seem a new English study a lower intelligence quotient (IQ) to have.
On the other side of the IQ increased in children who complied with a healthy diet . Who a lot of salad, rice, Pasta, fish, fruits and vegetables at the time of the intelligence test was rewarded with an average of 1.2 points higher IQ.
Kate Northstone and her colleagues at the University of Bristol, which publishes its study online in the journal Journal of Epidemiology and Community Health have , assume that the nutrition three years therefore so important is because the brain shows in the first three years, the highest growth rate.
" studies have can show that the growth of the skull in this period to the later cognitive performance related. It is possible that a healthy diet help to provide the brain a perfect foundation for its development, "the researchers write in their conclusion. "But it's certainly still too early and more studies are needed to conclusively judge the relationship between nutrition at an early age and intelligence," she added.
North Stone and her colleagues have data from a total of 3966 children from the Avon Longitudinal Study of Parents and Children (ALSPAC) , a progressive leader cohort study of families evaluated from the South West of England. For the classification into different food categories parents had to hold the eating habits of their offspring on a specific questionnaire. The questions were related to each of the age of three, four, seven and eight and a half years . The researchers then analyzed the diet because of its components and reported to the children of the group .
They found three typical dietary groups at any time of the survey:
1) Refined Food: Characterized by a high fat - and sugar content and the eating of refined finished products.
2) Traditional food: Characterized by the eating of meat, poultry, potatoes and vegetables.
3) Healthy Eating: Characterized by the eating of salads, rice, pasta, fish, fruits and vegetables.
The intelligence test was passed with an average of eight and a half years . Therefore, the researchers used the Wechsler Intelligence Scale for Children. The average IQ of all children tested was 104 points.
After the investigators, the results for all possible variables, including gender, age test, education, breast feeding, etc., were adjusted; remained the only variable characteristic eating behavior. It was found that there was a strong negative correlation between IQ and the use of convenience foods at the age of three years , while the same correlation was positive with the intake of healthy foods at the age of eight and a half.
North Stone and her colleagues acknowledged some limitations of their study . For example, the maternal intelligence as a factor could not be evaluated. Similarly, the authors argued that the inclusion of all children, including those with learning difficulties, which are known to withstand an increased risk are suspended for eating disorders, the data may have negatively influenced.
way or another. A healthy diet was supposed to be on the plan at any education. Especially in this day and age where obesity and diabetes resulting diseases are no longer of old age, but their highest growth rates in children have .
