Children brought up on healthy diets are more intelligent pared 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.

(答案→)A
解析：
【小题1】 细节题，由第四段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可以知道答案，所以选A
【小题2】 细节题，可以用排除法，由第三段children with a “healthier” diet may get an IQ improvement.可以知道A；由第六段第一句Scientists tracked the long term health and happiness of around 14,000 children可以知道C；由最后一段Every 1 point increase in dietary pattern score was associated with a 1.67 fall in IQ. 可以知道D，所以选B
【小题3】 细节题，由倒数第二段最后一句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可以知道答案，所以选D
【小题4】 细节题，由倒数第四段第二行children consumed when they were three, four, seven and eight and a half years old可以知道答案，所以选D
【小题5】 推理题，由本文的主要意思“健康的饮食能提高孩子们的智商”，所以选C
