Sen. Bernie Sanders (I-VT) is pushing the Food and Drug Administration to place warnings on unhealthy foods that alert consumers to their links to Type 2 diabetes and obesity, which would likely entail affixing large black labels to certain sodas, snacks, and desserts.

Sanders wrote to FDA Commissioner Robert Califf earlier this month in his capacity as chairman of the Senate Health, Education, Labor, and Pensions Committee to ask for the agency’s implementation of “strong front-of-package labels so that all consumers, especially children, can understand which products are harmful to their health.”
