Children brought up on healthy diets are more
intelligent compared with their junk food eating partners, a new research
suggests．
Kids fed a diet packed high in fats, sugars, and
processed（加工） foods had lower IQs than those fed
pasta（意大利面食）, salads and fruit, it was found．
The effect is so great that researchers from the
University of Bristol said those children with a "healthier" diet may
get an IQ improvement．
Scientists stressed good diet was essential in a
child's early life as the brain grows at its fastest rate during the first
three years of life．
This indicated head growth at this time is linked to
intellectual ability and “it is possible that good nutrition（營養(yǎng)） during this period may encourage excellent brain
growth” ．
Scientists tracked the long term health and happiness
of around 14,000 children born in 1991 and 1992 as part of the West Country's
Avon Longitudinal（縱向的）Study of Parents and Children （ ALSPAC） ．
Parents were questioned about the types and frequency
of the food and drink their children consumed when they were three, four, seven
and eight and a half years old． According to their
different changing form, these children were marked and given grades which
ranged from minus two for the most healthy to10 for the most unhealthy．
In the research, IQ was measured of 4,000 children
when they were eight and half years old, using a validated（經(jīng)過認證的）test－the Wechsler Intelligence
Scale（韋氏兒童智力量表） for Children．
The results found after taking account of some
influential factors, a leading processed food diet at the age of three was
associated with a lower IQ at the age of eight and a half , whether the diet
was improved after that age．
Every l point increase in dietary pattern score was
associated with a l.67 fall in IQ．
