A new study finds little evidence that organic food is much healthier than conventionally grown food.
Researchers at Stanford University report that eating organic fruits and vegetables can lower exposure to pesticides. But they say the amount measured in non-organic produce is very small and within safety limits.
As for nutritional value, organic food did not prove to be more nutritious.
One of the researchers involve in the study says the finding came as a surprise, But Dr. Dena Bravata notes "there are many reasons why someone might choose organic foods over conventional foods," from environmental concerns to taste preferences.
While organic food can cost considerably more, demand is rising.
The government says the foods accounted for more than $31 billion in sales last year, up from $3.6 billion in 1997.
