Organic Foods No More Nutritious, Safe than Conventional, Study Says
Organic foods areِ no moreِ nutritious thanِ conventionally grown foods, andِ no lessِ likely toِ beِ contaminated withِ certainِ bacteria, according toِ a newِ review ofِ studies.
However, organics wereِ lessِ likely toِ containِ pesticide residues, orِ harbor bacteria thatِ were resistant toِ antibiotics, compared withِ conventional alternatives, theِ study found.
Though farming practices vary, organic plants areِ generally grown withoutِ theِ use ofِ pesticides orِ industrial fertilizers, andِ organically raised animals areِ not routinely treated withِ antibiotics orِ growth hormones.
What the researchers found
Smith-Spangler andِ her colleagues analyzed data fromِ more thanِ 200 studies comparing nutrient andِ contaminant levels inِ organic andِ conventional foods, including fruits, vegetables, grains, meats, poultry, milk andِ eggs.
Despite theِ widespread perception thatِ organically produced foods areِ more nutritious thanِ conventional alternatives, weِ didِ not find robust evidence toِ support thisِ perception, theِ researchers wrote.
About 7 percent ofِ organic produce, andِ 6 percent ofِ conventional produce wasِ contaminated withِ E.
What the findings mean
Experts haveِ debated theِ routine useِ ofِ antibiotics inِ animal farming.
It isِ impossible toِ sayِ fromِ this study whetherِ oneِ method ofِ farming isِ betterِ than theِ other, thoughِ we areِ not seeingِ the negatives associatedِ with organics thatِ we areِ with someِ ofِ the conventional products, saidِ Gene Lester, a plant physiologist forِ the Agricultural Research Service ofِ the United States Department ofِ Agriculture inِ Maryland.
While theِ findings areِ interesting, heِ cautioned, theyِ areِ far fromِ definitive.
The review is published today (Sept. 3) in the Annals of Internal Medicine.
