Why the Potato Industry Is Fighting to Keep Its Vegetable Status

The National Potato Council testified in September before the Dietary Guidelines Advisory Committee, the body tasked with reviewing nutrition science ahead of the 2025 edition of the Dietary Guidelines for Americans (DGAs), arguing that potatoes' status as a vegetable — not a grain — is the line at stake in this review cycle. The council's core message, as described in its own account of that testimony, was blunt: potatoes are a vegetable, not a grain, and any move to blur that line would be unsupported by science.

That this needed saying at all is the notable part. The DGAs are revised every five years and, per the National Potato Council, they underpin every federal nutrition policy and feeding program that follows — meaning a technical reclassification debate in an advisory committee room has downstream effects on menus, purchasing, and public messaging nationwide.

The Dietary Guidelines Advisory Committee's job, as the National Potato Council describes it, is to weigh current nutrition evidence and hand USDA and the Department of Health and Human Services a set of recommendations; those two agencies then write the final DGA document. NPC's testimony is one input among many the committee considers before that handoff.

The specific concern NPC raised was that the committee is reportedly considering changes to how food groups are organized within U.S. dietary patterns, including treating starchy vegetables and grains as interchangeable. NPC's position is that this framing conflates two food groups that contribute differently to the diet — pointing to potatoes' potassium, calcium, vitamin C, vitamin B6, and fiber content as distinct from what grains typically provide.

NPC's argument, laid out in its own account, is that no scientific metric supports moving potatoes out of the vegetable category — it characterizes the idea instead as resting on "arbitrary preferences of meal substitution." The stated worry is practical: if guidance shifted, consumers could be confused about what to eat, potentially widening nutrient gaps and reducing vegetable intake overall, since Americans already don't eat enough vegetables by the council's account.

This is where the piece is worth reading as advocacy rather than settled science — NPC is one stakeholder presenting its case to a committee that will weigh competing input from others, including the nutrition activists the council references as favoring different foods as "healthier." The source material does not detail those opposing arguments, only NPC's characterization of the stakes.

One concrete policy thread NPC highlights is potatoes' role in the National School Lunch and School Breakfast Programs, where the council describes potatoes functioning as a "springboard vegetable" — introducing children to less-familiar vegetables, lifting program participation, and cutting food waste. If that framing holds, a shift in how potatoes are classified in dietary guidance could ripple into school menu planning specifically, not just abstract nutrition messaging.

Taken together, NPC's account frames the 2025 DGA cycle as a venue where category definitions — not just quantity recommendations — are genuinely contested. The council frames its ask as wanting growers to have "an equal seat at the DGA writing table," positioning this less as a single skirmish and more as an ongoing campaign it intends to continue through the full 2025 process.
