Washington / DC. (gov) A substantial and recurring feature of national media reporting – on TV, in newspapers and on the web – is devoted to nutrition and health. There, doctors and public health officials express concerns about obesity, diabetes, and the quality of the diet of many Americans. However, junk food shows little sign of waning in popularity. And every devil has its advocate, as this week was National Junk Food Day. It celebrates the naughty temptations on offer, notably at the nearly quarter-million fast food outlets across the country, which employ 3.6 million workers. Still, Americans are increasing the amount of fruits and vegetables they consume – daily averaging over 11.5 ounces of fruits and about 12.5 ounces of vegetables – according to the U.S. Census Bureau.
