A healthy diet can improve children's IQ
shows that there is a link between refined food and slightly lower IQ.
in the journal Epidemiology and community health, their article argues that poor nutrition may affect brain development.
the British Dietetic Association says that more and more young parents need to learn how to eat healthfully.
a total of 3966 children, aged 3, 4, 7, and 8 and a half, were enrolled in the project entitled "longitudinal study of the children of Ivan".
researchers say there are three types of dietary patterns: refined dietary patterns - high fat, high sugar and fast food; traditional eating patterns - meat, potatoes and vegetables; healthy eating patterns - salad, fruit and fish.
to 8 and a half years old, all children take IQ tests.
brain development
researchers found that no matter what other factors, such as the educational level of the mother, the social class, the time for breastfeeding, and so on, the intelligence quotient and diet still have an inevitable link.
when children were 3 years old, they ate more refined foods and diets. At 8 and a half years, IQ scores were slightly lower. This shows that early eating habits have a long impact on people.
Dr. Emmet, who works at the University of bolst, said: "the early life of the brain is much faster, and most of the brain development is done at this stage. It seems to be less important in the later period. "
even though the relationship between eating habits and intelligence quotient is very close, the effect is very small. The finishing diet pattern just lowered the IQ test by several points.
experts in the field say the conclusion is consistent with common sense.
Fiona Ford, a spokesman for the British Dietetic Association, said: "we should pay more attention to the long-term consequences of eating habits, and people are familiar with the short-term consequences."
"this study repeats the knowledge we already know, but it is not enough. Sometimes, society needs to help people change. We need to educate our younger parents and how to eat healthily. "A lot of people know how to do it, and some people don't want to cook food well," said Chris snow white, a nutritionist at
Royal Hospital of Lance.
"I absolutely agree with you eating a bit of weird food that you want to eat, but every week like this, there's something wrong with it."
"people should consult a registered dietitian, but the conclusion is often simple: a proper intake of fat; five kinds of fruits and vegetables a day; the staple food of whole grain."
