Organically grown wheat may have different labeling and a higher price
in stores, but it contains essentially the same profile of amino acids,
sugars and other metabolic substances as wheat grown with conventional
farming.
That's the conclusion of a German study, which produced perhaps the
most comprehensive metabolic profile of wheat from organic and
conventional agriculture.
Christian Zorb and colleagues did the research, scheduled for
publication in the Oct. 18 issue of the biweekly ACS Journal of
Agricultural & Food Chemistry. They were careful to use an approach
that avoided some of the shortcomings of past studies. "The statistical
analysis of the data shows that the metabolic status of the wheat grain
from organic and mineralic farming did not differ in concentrations of
44 metabolites," they report.
"This result indicated no impact or a small impact of the different
farming systems. In consequence, we did not detect extreme differences
in metabolite composition and quality of wheat grains."
Zorb and colleagues said organic agriculture is at least an
alternative to conventional agriculture, noting that it uses less
fertilizer and no herbicides or pesticides, while providing the same
nutritional quality.
