Research Shows Organic Tomatoes Are Richer In Healthy Nutrients

July 3, 2012: 12:47 AM EST
Spanish researchers have shown that organically-grown tomatoes are richer than conventional  tomatoes in compounds that are beneficial to human health. Known as polyphenols, the compounds have been associated with prevention of cardiovascular and degenerative diseases, as well as some forms of cancer. The researchers say the difference between organic and conventional tomatoes is found in the manure used as fertilizer in organic farming. Plants respond to the manure by activating defense mechanisms that increase the levels of all antioxidants. “The more stress plants suffer, the more polyphenols they produce,” the authors said.
