Organic Tomatoes Have Increased Concentrations Of Sugars, Vitamin C, Lycopene

February 20, 2013: 12:00 AM EST
Though some studies have concluded that there is no evidence that organic farming produces more nutritious fruits and vegetables, a new study finds that tomatoes grown on organic farms  amassed more nutrients linked to stress resistance. According to the Brazilian authors, organic farming exposes plants to greater stress than conventional farming. The tomatoes they grew were about 40 percent smaller than conventionally grown tomatoes, but accumulated higher concentrations of sugars, vitamin C and pigment molecules like lycopene, an anti-oxidant compound.
