I have lived in Australia and Germany and have traveled in other western countries, and the difference in food selection between other those countries and the United States is astounding. From granola to yogurt, breads to meat - it is difficult to find good foods in the US that are not overly processed. I'm 34, and it has changed quite a bit in my lifetime. Take yogurt for example, when I was a kid, yogurt tasted like yogurt - now the only national brand that even resembles yogurt is Activia. It's like food producers were forced to reintroduce real yogurt with active cultures because probiotics became popular. Everything else was milk with gelatin added to make it "yogurt".
And I live southern California, where there is a decent market for quality food. I have recently been traveling to rural Maryland and Virginia for work - I doubt 5% of the food in those grocery stores needed to be chilled or frozen - it is almost all over-processed crap.
