Researchers at that Swedish University of Agricultural Sciences, Alnarp, and Lund University compared the cancer fighting abilities of strawberries grown five different ways, including organically grown strawberries. Certain extracts in the strawberry inhibit cancer cell proliferation. The difference in how much the cancer cells are inhibited can from how the strawberry was grown.
During this study extracts from the regularly grown strawberries inhibited the colon cancer cells by 49% and the breast cancer cells by 38%. However, extracts from strawberries grown organically inhibited the colon cancer cells by 60% and breast cancer cells by 53%. The organic group was also higher in Vitamin C and antioxidents.
As if the simple sweetness of fresh-picked strawberries from our own backyard plants weren't enough incentive to grow some.
