The study confirms a long-held suspicion among some nutritionists and agricultural scientists that heavy use of pesticides and chemical fertilizers in modern agriculture can disrupt the ability of crops to synthesize certain phytochemicals-compounds that have antioxidant antioxidant, substance that prevents or slows the breakdown of another substance by oxygen. Synthetic and natural antioxidants are used to slow the deterioration of gasoline and rubber, and such antioxidants as vitamin C (ascorbic acid), butylated hydroxytoluene properties and are associated with reduced risk for cancer, stroke, heart disease, and other illnesses.
Researchers tested corn, strawberries, and marionberries (a type of raspberry) for the presence of phenolic phe·no·lic

Phenolics include some flavinoids found in grapes and other red fruits and vegetables, and vitamin C vitamin C

(ascorbic acid) found in most citrus fruits. All produce came from the same farm in Oregon, which grew the crops under organic (no synthetic pesticides or fertilizers), sustainable (reduced or no synthetic pesticides), and conventional conditions, while keeping crop variety, soil type, and time of harvest consistent.
Sustainably grown corn contained 58 percent more phenolics than conventionally grown Conventionally grown is an agriculture term referring to a method of growing edible plants (such as fruit and vegetables) and other products. It is opposite to organic growing methods which attempt to produce without synthetic chemicals (fertilisers, pesticides, antibiotics, corn, and organic corn contained 56 percent more. Similar results were found for marionberries. Sustainably grown strawberries contained 19 percent more total phenolics than conventionally grown strawberries. (Organic samples were not available for strawberries.) This is the first study to show a correlation between growing technique and phytochemicals, according to lead author Alyson Mitchell, an assistant professor at the UCD's Department of Food Science and Technology.
"Lots of these compounds are synthesized to protect the plant from insects and disease," said Mitchell. "So if we're protecting the plant with pesticides, the plants are not going to waste the energy to produce them." On the other hand, organically and sustainably grown crops, raised with Little or no pesticides, must rely on their own defenses. Of course, conventional crops are also exposed to pest pressures, so Mitchell and her team plan to examine whether the use of agrochemicals may directly disrupt plant production of these beneficial compounds. Mitchell speculates that slightly higher level of phytochemicals in the sustainably grown samples compared to the organic samples may reflect more adequate nutrient availability, as all sustainable crops were treated with synthetic fertilizers.
