The argument for organic food is that, because it does not contain nearly as many pesticides, hormones, antibiotics, and contaminants, organic food is both safer and more nutritious.
Which argument is correct?
One way to find out would be to use what engineers call a comparative analysis. In a proper comparative analysis, two trials are compared, where the only major variable that is different between the trials is the variable of interest. (If too many significant variables are present, they can obscure the actual results and yield misleading or erroneous conclusions.)
Many trials have already been done of organic versus commercial farming of plant-based foods. A recent study (“Nutritional, food safety benefits of organic farming documented by major study“) reviewed the results of these trials, wherein most of the trials were well-controlled to minimize variables. The conclusion was that organic foods were indeed clearly much safer and much more nutritious. “This study is telling a powerful story of how organic plant-based foods are nutritionally superior and deliver bona fide health benefits,” said Charles Benbrook, co-author.
