Buying organic food has significant advantages, such as eliminating antibiotics and artificial pesticides from your child’s plate and helping the bottom line of small farmers who do not use fertilizers that foul rivers and streams.

Once viewed as a niche product, organic produce is now served in millions of American homes from the White House on down. But despite a presumption by some consumers that this often-pricy produce is superior to the conventional kind in every conceivable way, a new study by researchers at Stanford University found that organic fruits and vegetables deliver no more vitamins or other nutrients than conventionally grown produce. “I was absolutely surprised,” lead author Dena Bravata told the Associated Press, after her meta-analysis of 237 studies.
