All organics aren't created equal. Here's what's hidden behind the label.
MYTH #1: ORGANIC FOOD IS ALWAYS BETTER FOR THE ENVIRONMENT.
Organics don't contaminate soil and groundwater with pesticides and chemicals like regular farming does, but there's a surprising downside: Since organic farming is only about half as productive as conventional farming, it requires far more land to produce the same amount of food. Dennis Avery of the Hudson Institute's Center for Global Food Issues estimates that modern high-yield farming has saved 15 million square miles of wildlife habitat, and that if the world switched to organic farming, we'd need to cut down 10 million square miles of forest. Less-productive farming could also lead to even less food for the world's undernourished.
MYTH #2: IT'S MORE NUTRITIOUS.
Studies keep flip-flopping on this: One found more vitamin C in organic tomatoes than in conventional ones; another found more cancer-fighting flavonoids in organic corn and strawberries. But other studies haven't found organics to have a nutritional edge. What makes the biggest difference in nutrients is how long produce sits on the shelf. Spinach, for instance, loses about half of its foliate within a week.
MYTH #3: IT TASTES BETTER.
Nobody has been able to tell the difference except in one study of apples, where organics came out ahead. To get raspberries that taste raspberrier, buy produce that's locally grown, is in season, and hasn't been sitting on the shelf too long. Let's face it: Nothing is at its best when it's flown halfway around the world and waxed, then has to spend a week in the grocery store.
MYTH #4: YOU DON'T HAVE TO BE AS CAREFUL ABOUT WASHING IT.
All produce, whether purchased from a grocery megachain or your local organic farm, is susceptible to nasty bacteria, such as E. coli (the news-maker that's also been known to kill people). Soil and runoff water that's contaminated with E. coli-harboring animal poop can get onto produce — particularly melons, lettuce, sprouts, tomatoes, spinach, and green onions, since they grow close to the ground. Your best defense: Wash everything thoroughly under running water.
