IS ORGANIC FOOD REALLY SAFER AND HEALTHIER?
September 20, 2004
Americans spent $10.4 billion on organic foods last year, but several studies are questioning the assumption that organic foods are safer and healthier than conventional foods.
A recent survey indicated that two out of three consumers choose organic foods because they support "better health," but two recent symposia (the American Chemical Society and the First World Congress on Organic Food) have concluded that evidence is lacking to support the claimed superior benefits of organic foods. Furthermore,
- A report by the Texas Department of Agriculture indicates that conventional produce was eight times more likely to have pesticide residue than organic, but of the few samples in which a residue was found, the amount was negligible (between 1 and 5 percent of government standards).
- Because organic farmers rely on cow and pig manure for fertilizer, organic foods are vulnerable to bacterial contamination -- two recent outbreaks of E-coli involved organic strawberries and lettuce.
- Free-range birds (organic poultry) have higher rates of bacterial contamination than conventional poultry due to their higher exposure to wild bird droppings.
Moreover, a study by the American Council on Science and Health reveals that organic produce does not have significantly higher vitamin contents than conventional produce. A comparison of organically and conventionally grown vegetables revealed that a higher vitamin C content for the organic vegetables, but only by about 10 percent of the recommended daily intake, which can be compensated for when adding fruits.
What is important, say observers, is that consumers make fruits, vegetables and dairy products a part of their diet, and they should not feel guilty if they can't afford more expensive organic foods.
