"Most parents of kids aged 4 or 5 are not aware if their children are overweight or obese, a new study has found.
Researchers from the University Medical Centre Groningen in The Netherlands reached the conclusion after observing 800 parents and 439 children who took part in study.Among those participating five percent of the children were overweight, four were obese and the rest were normal weight."
It was found that half of the mothers who took part in a study thought that their obese four or five year old was normal weight, as did 39 percent of the fathers."
Whether or not parents are aware of potential weight problems, another new study finds that listing nutritional information on fast-food menus increases the chance parents will choose lower-calorie meals for their children.
According to lead researcher Dr. Pooja Tandon, a graduate fellow in the department of general pediatrics at the University of Washington in Seattle, “When parents are provided with calorie information they chose about 100 calories less for their three to six-year-old child compared to parents who didn't have that information.” She also pointed out, “One hundred calories over time is actually a significant amount in terms of weight gain, given the rates of fast food consumption and childhood obesity in our country.”
