Fat still on the children's menu
August 16, 2007Parents should think twice before offering a low-fat menu to youngsters, despite concerns over obesity. Children burn more body fat than adults for each calorie spent, according to research in the online open access publication, Nutrition Journal, evidence that fat can be included as part of a child's healthy and balanced diet.
A US team led by John Kostyak from The Pennsylvania State University used calorimetry to measure whole body fat oxidation in 10 children (aged 6-10) and 10 adults. All had a body mass index (BMI) within the healthy, middle range. Kostyak's team checked subjects' cardiovascular fitness and body fat, and all were given the same typical American diet for three days prior to testing (although adults had larger portions). Test subjects spent nine hours on three separate days at a low physical activity level, watching movies or reading, in either a room calorimeter or under a hood system, which quantify oxygen and carbon dioxide gas levels. The authors also measured the total amount of nitrogen in the subjects' urine, and used these measurements to calculate how much fat they oxidised.
Although the absolute amount of fat burned in a day did not differ greatly between children and adults, children burned considerably more fat relative to the amount of energy they used. In an attempt to determine the contribution of fat oxidation to daily calorie expenditure, the researchers calculated the grams of fat oxidized per kcal of energy expenditure. This value was higher in children (0.047± 0.01 g/kcal) compared to adults (0.032± 0.01, p<0.02). Women and girls used fat at a higher rate than men and boys of a comparable age.
"Prepubescent children may oxidise more fat relative to total energy expenditure than adults for the purpose of supporting normal growth processes such as higher rates of protein synthesis, lipid storage and bone growth" says Kostyak. "Sufficient fat must be included in the diet for children to support normal growth and development."
The findings support current dietary guidelines, suggesting that children should have a certain amount of fat in their diet, to meet their energy and nutritional needs.

Black patients with chronic pain less likely to have obesity assessed
At the intersection of two U.S. health epidemics - obesity and chronic pain - researchers from the University of Michigan Health System found black patients with chronic pain were less likely to have their weight or body mass index (BMI) recorded, even though they are at higher risk for having obesity when compared with their white counterparts.
