Studies investigating the chemical differences between organic and conventionally grown produce are difficult to carry out, in part because many factors cannot be ruled out, such as annual differences in weather and other environmental factors. A six-year study in onions shows that organically grown onions contain higher levels of phytochemicals. The authors of the study believe that this difference is due to the higher level of stress organic onions experience compared to conventionally grown onions. Another onion-related news years in the making: meet the Sunion. An onion produced through 30 years of old-fashioned cross-breeding, the Sunion doesn’t burn your eyes when cut.
