NEW YORK (Reuters Health) - Kids swap regular for varieties low fat dairy products consume less saturated fat but does not seem to lose weight, according to Australian researchers.
They found the weight or body (BMI) mass index had substantially changed six months after the children towards reduced or low fat dairy products.
Instead of trimming jump them, kids that reduces fat intake seemed to compensate by eating more calories from other sources, according to new findings, which appear in the American Journal of Clinical Nutrition.
Still, there may be other benefits for reducing the saturated fat, says Dr. Frank Franklin, Professor retired nutrition and Pediatrics at the University of Alabama at Birmingham, who was not involved in the study.
For example, it could help children to ward off heart disease when they grow up, Franklin told Reuters Health.
The study, Hendrie Gilly and Rebecca Golley Commonwealth Scientific and Industrial Research Organization divided 145 ages kids four to 13 in two groups. The researchers asked a group to replace their dairy products to low fat varieties for six months, while the other received no dietary advice.
The two groups consume similar amounts of dairy products, and total caloric intake has remained more or less stable during the study, which was funded in part by the dairy Australia.
The nurses interviewed children and parents on their products dairy food habits at baseline and at three and six months. They also drew the blood and measured BMI and waist circumference.
Low group fat made consume less overall fat. At the end of the study, they obtained 13.3% of their total calories from saturated fat, compared to 16.6% in the comparison group.
This is a significant change, Franklin noted, but still more than the 10% recommended by the U.S. Department of Agriculture. He added that young Americans are generally closer than Australians to get the recommended amount.
There was also a drop in cholesterol levels in the low fat group, but waist, BMI and weight were not different.
According to Greg Miller of the National Dairy (MCDV) Council, which represents the industry in the United States, this corresponds to other research on children, where the milk shows a positive impact or neutral on body composition.
"Many researchers said that if we get just consume the products of low in fat or reduced fat, we can have an impact on weight", Miller told Reuters Health.
But as shown in this study, children made up for the number of calories lost elsewhere in their diet. Looking only milk is not helpful as, Miller said.
Franklin said that it was safe to switch to more lean dairy products, which have lower cholesterol but the same amount of nutrients, calcium and vitamin d.
"The only thing done is fat saturated, that you do not need," he said, adding that skimmed and two per cent of fresh milk the same as whole milk.
