 According to an analysis published on the website of the libertarian Mercatus Center as well as published statements by economists, medical practitioners, and concerned consumers, many feel the FDA oversteps its regulatory powers and undermines small business and small farms in favor of large corporations.Three of the FDA restrictions under analysis are the permitting of new drugs and devices, the control of manufacturer speech, and the imposition of prescription requirements.The authors argue that in the increasingly complex and diverse food marketplace, the FDA is not equipped to adequately regulate or inspect food.
