Kennedy is right: All three of the principal health agencies suffer from agency capture. A large portion of the FDA's budget is provided by pharmaceutical companies. NIH is cozy with biomedical and pharmaceutical companies and its scientists are allowed to collect royalties on drugs NIH licenses to pharma. And as the former director of the Centers for Disease Control and Prevention (CDC), I know the agency can be influenced by special interest groups.

But it doesn't stop in the health agencies: the U.S. Department of Agriculture is a captive of industry, too. Created to help the family farmer and to ensure a wholesome food supply, today the agency often favors large corporations over the interests of small farmers and the public's health. To cure our children, we must reevaluate our food choices and the underlying practices of the agricultural sector. We must prioritize wholesome and nutritious food.

If we do not discover the depth of our corporate capture problem and fix it, we cannot truly address chronic disease in this country. The primary role of these vital agencies is to focus on public good, not corporate interests or personal profit—and most of the public servants working there are eager to do good.
