American Kids Need More Whole Grains, Veggies, Seafood, Report Says	American children's diets fall considerably short of meeting national dietary recommendations according to a new government report.	Researchers measured diet quality by giving children a score from zero to 100 with 100 representing a diet that fully met national dietary guidelines.	The average score was 50 for children ages 2 to 17 in 2007 and 2008 (the most recent period for which data was available). That score remained relatively unchanged from earlier years. (The average score in the 2005-2006 period was 47.)    	The researchers also looked at how well children fared in meeting the guidelines for specific food groups. Children came close to meeting guidelines for diary and protein intake with average scores in the 80s but generally ate far too little whole grains greens and beans with average scores ranging from 14 to 18.	The diet-quality scores of children and adolescents would be improved by increasing the intake of vegetables especially dark greens and beans replacing refined grains for whole grains substituting seafood for some meat and poultry and decreasing the intake of sodium (salt) and empty calories from solid fats and added sugars the report said.

Chronic diseases such as type 2 diabetes and cardiovascular disease may stem in part from childhood eating patterns according to the report from the National Institute of Child Health and Human Development.	In addition to examining diet the report looked at a number of other measures of children's well-being. Here are some of the findings:	The report also gave estimates about changing demographics. By 2050 about half of U.S. children will be Hispanic Asian or of two or more races the report said.	Follow Rachael Rettner @RachaelRettner. Follow LiveScience @livescience Facebook & Google+.
