August 7/Atlanta/Associated Press -- A big government study shows that in the past decade, the proportion of children who have high cholesterol has fallen.

The results are surprising, given that the childhood obesity rate did not budge. Some experts think that while most kids may not be eating less or exercising more, they may be getting fewer trans fats. That is because the artery-clogging ingredient has been removed or reduced in many processed or fried foods such as doughnuts, cookies and french fries.
