A push to ban sugary drinks, candy and more from the U.S. program that helps low-income families pay for nutritious food has been tried before—but it may soon get a boost from new Trump administration officials.

Robert F. Kennedy Jr., the newly confirmed Health and Human Services (HHS) Secretary, and Brooke Rollins, the new Department of Agriculture (USDA) Secretary, have both signaled that they favor stripping such treats from SNAP, the Supplemental Nutrition Assistance Program.

Kennedy has been most vocal, calling for the government to stop allowing the nearly $113 billion program that serves about 42 million Americans to use benefits to pay for “soda or processed foods.”

But removing certain foods from SNAP—known for years as food stamps—isn't as simple as it sounds.

The program is run by the USDA, not HHS, and is administered through individual states. It is authorized by the federal Food and Nutrition Act of 2008, which says SNAP benefits can be used for “any food or food product intended for human consumption,” except alcohol, tobacco and hot foods, including those prepared for immediate consumption.

Excluding any foods would require Congress to change the law—or for states to submit waivers to restrict purchases. Over the past 20 years, lawmakers in several states have proposed stopping SNAP from paying for bottled water, soda, chips, ice cream, decorated cakes and “luxury meats” like steak.

In the past, Agriculture Department officials rejected the waivers, saying in a 2007 paper that no clear standards exist to define foods “as good or bad, or healthy or not healthy.” In addition, restrictions would be difficult to implement, complicated and costly. And they might not change recipients' food purchases or reduce conditions such as obesity.

Anti-hunger advocates point to research that shows SNAP recipients are no more likely than other low-income Americans to buy sugary drinks or snack foods. And they say that limiting food choices undermines the autonomy and dignity of people who receive, on average, about $192 a month—about $6.31 per day.
