Declining Fruit and Vegetable Nutrient Composition: What Is the Evidence?
By Donald R. Davis
Journal of HortScience; February 2009, 5 pp.
SNIP
The Gist:
If the economy isn't grim enough for you, just check out the February issue of the Journal of HortScience, which contains a report on the sorry state of American fruits and veggies. Apparently produce in the U.S. not only tastes worse than it did in your grandparents' days, it also contains fewer nutrients - at least according to Donald R. Davis, a former research associate with the Biochemical Institute at the University of Texas, Austin. Davis claims the average vegetable found in today's supermarket is anywhere from 5% to 40% lower in minerals (including magnesium, iron, calcium and zinc) than those harvested just 50 years ago. (Read about Americans' Incredible, Edible Front Lawns.)
Highlight Reel:
1. On the Difficulty of Comparing "Then" and "Now:" Davis is quick to note that historical data can sometimes be misleading, if not altogether inaccurate. Take early measurements of iron in foods: because scientists failed to sufficiently remove clinging soil, iron levels appeared unusually high in certain vegetables like spinach, (which gave rise to the myth that it contained exorbitant amounts of the mineral - a myth further propagated by the popular cartoon character, Popeye). Then again, good historical data provides the only real-world evidence of changes in foods over time, and such data does exist - one farm in Hertfordshire, England, for example, has archived its wheat samples since 1843.
2. On the So-Called "Dilution Effect:" Today's vegetables might be larger, but if you think that means they contain more nutrients, you'd be wrong. Davis writes that jumbo-sized produce contains more "dry matter" than anything else, which dilutes mineral concentrations. In other words, when it comes to growing food, less is more. Scientific papers have cited one of the first reports of this effect, a 1981 study by W.M. Jarrell and R.B. Beverly in Advances in Agronomy, more than 180 times since its publication, "suggesting that the effect is widely regarded as common knowledge." (See pictures of fruit.)

Instead of buying expensive organic move out of US....
Fruit is delicious in Mexico,and Latin America, the Caribe etc.. I also notice the difference of flavor around the world, the most delicious fruit I ate was in Jericho, Palestine
