This is the VOA special English health report.
Researchers say American children now eat an average of 3 snacks a day between meals. A study found that those snacks add up to almost 1/3 of all the daily calories eaten by children. And those extra calories could help explain the rise in overweight children in the United States. The study was done at the University of North Carolina at Chapel Hill. The researchers studied the diets fo 31,000 children ages 2 to 18 over a 30-year period. They found that found snacking has increased since the 1970s.
And what kinds of snacks have been increased most? Salty, high fat foods like chips. The study also found the greater snacking on cake, cookies and other p**s that past generations might have saved for after dinner. The study is in the journal, Health Affairs. Nutrition professor Barry Palpkon was the lead of investigator, he says parents should limit snacks to one a day for children age 6 and older. He also advices parents and the care givers to provide healthy snacks like fruits and vegetables. Professor Pulpkins says American school also need to improve their nutrition. For example, schools may have vending machines that offer what many people would consider junk food. There has been a push for schools to offer more healthful snacks and lunch choices and fewer sugary drinks.
Earlier this month, Coca-cola said it would stop selling sugary drinks in American schools unless parents requested them. Its competitors as Pepsi just announced that they will stop sales of sugared drinks to schools worldwide. America's top public health officer wants to see more changes like this. ?Sergan? General Regina Benjamin, recently spoke to law makers about making healthy foods more available.
"There is a growing consensus that we as a nation need to recreate our communities and our environment with the healthy choices are the easy choices and the affordable choices."
Agriculture sacretary, Tom Wilsack, who has talked his own childhood struggles with weight agrees about the need.
"We need to do a much better job of making sure that "what's in the vendering machine" is very consistent. And we think that the time has come for standards."
First lady, Mechelle Obama, is leading a compaign to fight child who has obesity.
Public health officials reported in January that 17% of American children are severly over-weight.
