Do organically produced foods have higher nutritional value?
Other research from CSU focused on growing potatoes using four different farming techniques under the same growing conditions: an intensive high-chemical system; a moderate conventional system; customary organic farming and virgin organic production. Nine minerals and seven vitamins were analysed and no clear differences were discovered.
Another U.S. study found more soluble iron in conventionally grown spinach but the proportion of the soluble iron available to consumer’s system was somewhat higher for both spinach and peppers grown with compost and manure.
