A new research suggests that children who are brought up on healthy diets are more intelligent compared with those junk food eaters. It was found toddlers (蹒跚学步的孩子) who are fed a diet high in fats, sugars, and processed foods had lower IQs than those fed pasta, salads and fruit. 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 a good diet was vital 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 during this period may encourage the best brain growth.

Scientists followed 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 Study of Parents and Children (ALSPAC). Parents were quizzed 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. Their answers were marked on a sliding scale (浮动计算表). Minus two is for the healthiest while ten is for the unhealthiest. IQ was measured by a test—the Wechsler Intelligence Scale for Children (韦氏儿童智力量表) —of 4, 000 children when they were eight and a half years old. The results found after considering some other factors, a mainly processed food diet at the age of three was connected with a lower IQ at the age of eight and a half, but whether the diet was improved after that age would never influence the result. Every one point increase in dietary score was connected with a 1.67 fall in IQ.

With “O sugar (糖)” drinks taking the market by storm, “sugar control” has become one of the most important topics for young people today.

Singapore started to put labels (标签) on every drink recently. The labels are from A to D. A is the most healthy, and D is the least healthy. The more sugar and saturated fat (饱和脂肪), the less healthy the drink is. D-grade drinks aren’t allowed to be advertised (打广告) by companies to attract customers.

Shanghai is the first city in China to set health tips for sugary drink to deal with health problems because of too much sugar intake. 159 stores in the city begin to put three-coloured (red, orange, green) labels on the drinks.

A green label means customers should read the drink’s nutrition label (营养成分表); Orange labels warn customers to limit their added sugar intake; and red labels means you’d better not drink or drink less.
