11.Could eating fast food be bad for more than just your health?New research has found proof that eating foods high in sugar and fat could also be bad for your IQ.Researchers from the United Kingdom and Canada looked at what children ate when compared to their IQ levels.The researcher used surveys to ask parents how often their children ate junk food.The parents were surveyed when the children were aged 3,then followed up 5years later to see how the diet affected the growing children's IQ.They found that those who ate more junk food had lower IQ levels than those who ate a more nutritious diet.
"This suggests that any cognitive(认知的) effects relating to eating habits early in childhood may well continue to exist in later childhood,despite any later changes (including improvements) to dietary intake,"the authors wrote.
The researchers found that dietary habits between the ages of 4and 7did not have as much of an effect as what children ate at age 3did.This may be because the brain grows the quickest during the first three years of life,and thus is more easily affected by things such as diet.
"A possible explanation for this is that the brain grows at its fastest rate during the first three years of life.Studies have shown that head growth during this time is associated with cognitive outcome,and it is possible that good nutrition during this early period may encourage brain growth,"the researchers wrote.
The researchers point out that they have found an association between food and IQ,but not a direct cause or effect.Other factors could have played a role in determining a child's IQ.Parenting,genetics,and even family income are all factors that determine how intelligent a child will be.
Despite this,nutritionists tell us that what children eat can affect how healthy they are,how much rest they get,how smart they are during school.All of these things could change a child's test on IQ level.It is not clear whether food affects IQ directly or indirectly.
More research is needed to determine if there is a direct effect between what a child eats and how intelligent they are.However,the study does suggest that there may be more reasons than just physical health to make sure a child gets a healthy diet.
