study published last year claimed that organic food has no additional
health benefits over non-organic food. But now, a new study not only
shows that organic
strawberries offer more nutritional value than conventional
strawberries, but they also make soil healthier.
from last year, which was published in The
American Journal of Clinical Nutrition and
led by Dr. Alan Dangour, claimed that organic chicken, beef, milk,
fruit and vegetables do not provide any additional nutritional
advancement to a person's diet. According to Dangour and his team,
there is a small number of nutritional differences between organic
and non-organic foods, such as the fact that organic foods have more
phosphorous. But Dangour insists that phosphorous is available in
everything people eat and is "not important for public health."
is also higher in organic produce, but acidity is about taste and
sensory perception and makes no difference at all for health,"
said Dangour. "Our review indicates that there is currently no
evidence to support the selection of organically over
conventionally-produced foods on the basis of nutritional
a new study challenges Dangour's research, but only where
strawberries are concerned. According to the
new study, which was published in PLoS
One and lead by Washington State University, organic
strawberries are more nutritious and flavorful than those that are
grown through chemical-laden farming. Also, organic strawberries
leave soil genetically diverse and healthier.
percent of the U.S. strawberry crop is grown on farms in California,
so the Washington State researchers analyzed 31 biological and
chemical soil properties and soil DNA as well as the quality,
nutrition and taste of three types of strawberries on 13 chemical
farms and 13 organic farms.
results of their research were that organic strawberries
had a longer shelf life, much higher antioxidant activity, more dry
matter and higher concentrations of ascorbic acid and phenolic
compounds than non-organic strawberries. In addition, anonymous
testers were asked to taste the different kinds of strawberries, and
many of them found that one type of organic strawberries has sweeter
and better flavor than the others, as well as a better appearance.
analyzing the soil these organic strawberries were grown in, the
researchers found that this organically managed soil had
diversity, and also beat the non-organic soil in terms of carbon
sequestration, micronutrients, microbial biomass and enzyme activity.
