愉快的寒假南京出版社系列答案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 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(营养)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(纵向的)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 to 10 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(经过认证的)test-the Wechsler Intelligence Scale(韦氏儿童智力量表)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 1 point increase in dietary pattern score was associated with a 1.67 fall in IQ.

Even a small reduction in salt in the diet can be a big help to the heart. A new study used a computer model to predict how just three grams less a day would affect heart disease in the United States.
The result：10％ fewer heart attacks. 8％ fewer strokes. 4％ fewer deaths. 11％ fewer new cases of heart disease. And 240 billion dollars in health care savings.
Researchers found it could prevent 10，000 heart attacks and 9。200 deaths every year.
The study is in the New England Journal of Medicine. Kirsten Bibbins-Domingo at the University of California San Francisco was the lead author. She says people would not even notice a difference in taste with three grams， or one-half teaspoon，less salt per day. The team also included researchers at Stanford and Columbia Uni versity.
Each gram of salt contains four hundred milligrams of sodium（钠），which is how foods may list their salt content.
The government says the average American man eats ten grams of salt a day. The American Heart Association advises no more than three grams for healthy people. It says salt in the American diet has increased fifty percent since the nineteen seventies， while blood pressures have also risen. Less salt can mean a lower blood pressure.
New York City Mayor Michael Bloomberg is leading an effort called the National Salt Reduction Initiative. The idea is to put pressure on food companies and restaurants. Critics call it government interference.
Mayor Bloomberg has already succeeded in other areas， like requiring fast food places in the city to list calorie information. Now a study by the Seattle Children’s Research Institute shows that the calorie information on the menu can influence what parents order for their children.
