Irrespective of whether America's childhood obesity epidemic has genetic roots, the problem can be attacked head-on through healthier school lunches, less time in front of the tube and exercise. This may seem like common sense, but there is a study now that confirms it. A study in the American Heart Journal by the University of Michigan Cardiovascular Center concludes that while genetic screening might be appropriate for the extremely obese, "increasing physical activity, reducing recreational screen time and improving the nutritional value of school lunches offers great promise to begin a reversal of current childhood obesity trends."
