At least “vegetarian” still means something.
From the Associated Press:

Patient after patient asked: Is eating organic food, which costs more, really better for me?

Unsure, Stanford University doctors dug through reams of research to find out — and concluded there’s little evidence that going organic is much healthier, citing only a few differences involving pesticides and antibiotics.

Eating organic fruits and vegetables can lower exposure to pesticides, including for children — but the amount measured from conventionally grown produce was within safety limits, the researchers reported Monday. Nor did the organic foods prove more nutritious.

Organic foods did have some demonstrable value.

Her team did find a notable difference with antibiotic-resistant germs, a public health concern because they are harder to treat if they cause food poisoning.

Specialists long have said that organic or not, the chances of bacterial contamination of food are the same, and Monday’s analysis agreed. But when bacteria did lurk in chicken or pork, germs in the nonorganic meats had a 33 percent higher risk of being resistant to multiple antibiotics, the researchers reported Monday in the journal Annals of Internal Medicine.

The last paragraph of the article makes a critical point.

Organic produce had a 30 percent lower risk of containing detectable pesticide levels. In two studies of children, urine testing showed lower pesticide levels in those on organic diets. But Bravata cautioned that both groups harbored very small amounts, and said one study suggested insecticide use in their homes may be more to blame than their food.

What’s not clear from the report is how the tested products were certified as “organic.” As noted in July, there’s been a political struggle to define the word to the benefit of multinational companies.

Discuss.
