Diet foods linked to obesity in childrenDate: 08/08/2007 09:31:08

Low-calorie food aimed at children may lead to overeating and increase the risk of obesity, researchers have found.
The scientists at the University of Alberta in Canada fed rats diet versions of normal foods, observing that they were then liable to overeat regardless of whether they were already obese or not.
The study, which has been published in the journal Obesity, concluded that low-calories foods can work to disrupt the body's ability to regulate the intake of calories through the use of taste.
Professor David Pearce, the scientist who led the research, said: "Based on what we've learned, it is better for children to eat healthy, well-balanced diets with sufficient calories for their daily activities rather than low-calorie snacks or meals."
However, the older rats involved in the experiment were found to be able to rely on their sense of taste to assess the calorific content of their food and were therefore less likely to overeat and gain weight.
According to the latest figures from Heart Research UK, the rate of childhood obesity has doubled in the last ten years, with one in four children significantly overweight.
