Most people think of USDA as a farm agency. But Congress gave USDA a parallel mission in food and human nutrition — not just producing food, but understanding what it does to the people who eat it. For the nutrition assistance programs that put food on the table, see [SNAP benefits](snap-benefits.md). **7 U.S.C. §§ 3171–3179** establishes USDA's mandate for **human nutrition research, dietary guidance, and nutrition education** — including the flagship **Expanded Food and Nutrition Education Program (EFNEP)**, which has operated since 1969 as the federal government's primary grassroots nutrition education program for low-income families.

USDA conducts nutrition research through its Agricultural Research Service and Economic Research Service, surveys Americans' diets through the What We Eat in America study, publishes the **Dietary Guidelines for Americans** (jointly with HHS), and runs education programs — including the predecessor to SNAP-Ed — through the cooperative extension network at land-grant universities. The entire framework traces back to this subchapter's 1977 mandate for a "separate and distinct" USDA nutrition mission.

## How It Works

### EFNEP — The Grassroots Nutrition Program

The **Expanded Food and Nutrition Education Program (EFNEP)** is the largest direct-delivery nutrition education program in the country that most people have never heard of. Running since 1969, EFNEP works through cooperative extension offices at land-grant universities in all 50 states, DC, Puerto Rico, and U.S. territories.

The model is deliberately ground-level: EFNEP hires **paraprofessional aides from the communities it serves** — specifically, low-income individuals who are trained to teach their neighbors nutrition basics. The law requires that, to the maximum extent practicable, program aides be hired from the local community. A low-income mother teaching other low-income mothers is more effective than a professional from outside the community, and the law recognizes this.

EFNEP programs teach families how to:
- Stretch food budgets while buying more nutritious food
- Read nutrition labels and evaluate food quality
- Safely prepare, store, and preserve food
- Coordinate food assistance (SNAP, WIC) with household food planning

The $90 million annual authorization covers a funding formula that guarantees every state gets at least as much as it received in 1981 (the baseline year), with additional funds distributed based on each state's share of population living at or below **125% of the poverty line**. Historically Black land-grant institutions (1890 institutions) receive a dedicated funding share that grows from 10% to 15% of above-baseline funds by 2014.

### USDA Nutrition Research

The mandate in § 3173 — to make nutrition research a "separate and distinct mission" of USDA — institutionalized what had been a peripheral function. USDA's Human Nutrition Research Center network (including major centers in Houston at Baylor, in Boston at Tufts, and the Beltsville Human Nutrition Research Center in Maryland) conducts the fundamental science behind dietary recommendations: how many calories people actually need, how nutrient absorption varies with age, how processing changes the nutritional profile of food.

USDA also maintains the **USDA Nutrient Database** — the foundational reference dataset used by food companies, restaurants, healthcare providers, and calorie-counting apps to understand what's in American food. The law specifically requires this database to be continuously updated.

### National Nutrition Monitoring

The § 3178 monitoring mandate produced the **National Nutrition Monitoring and Related Research Act of 1990**, which established the ongoing **What We Eat in America** dietary intake survey — conducted jointly by USDA (through NHANES with CDC/NIH) and HHS. This survey is the empirical foundation for knowing whether Americans are actually following dietary guidance, and which populations are most nutritionally at risk.

### Behavioral Economics for Healthy Eating

Section 3179 reflects a newer approach: rather than just educating people about what they *should* eat, the law funds research on how the **design of food environments** affects what people actually choose. How does where schools place fruit vs. French fries affect student choices? Does a cafeteria tray design affect portion size? These "choice architecture" interventions — informed by behavioral economics research — are coordinated with SNAP and USDA food program operations to scale what works.

## How It Affects You

**If you receive SNAP benefits and want to stretch your food budget further**: The **Expanded Food and Nutrition Education Program (EFNEP)** is a free, federally funded program specifically designed for you — offered in every state through cooperative extension offices at land-grant universities. EFNEP teaches practical skills: reading nutrition labels, planning meals that meet your nutritional needs on a SNAP budget, safely storing food to reduce waste, and cooking techniques that make nutritious food accessible and appealing. Classes are typically small groups led by paraprofessional educators from your own community. **SNAP-Ed** (a parallel program administered by USDA's Food and Nutrition Service rather than NIFA) offers similar programming, sometimes jointly with EFNEP.

To find EFNEP or SNAP-Ed in your area: call or visit your county **Cooperative Extension** office — search your state's name + "Cooperative Extension" or go to **extension.org** for a directory. In most states, you can also call 211 (the social services helpline) and ask for nutrition education resources. You don't need to be enrolled in SNAP to participate in EFNEP, though the program prioritizes households at or below 125% of the poverty line.

If you're interested in the **GusNIP incentive program** — which gives SNAP participants bonus money when they buy fruits and vegetables at participating locations — search for "Double Up Food Bucks" or your state's SNAP incentive program through **fns.usda.gov/snap/gusnip-nutrition-incentive-program**. Participating farmers markets, grocery stores, and food co-ops effectively double your produce purchasing power.

**If you run a school, child care center, or afterschool program and want to improve children's food choices**: The behavioral economics research funded under **7 U.S.C. § 3179** has generated a toolkit of low-cost, high-impact interventions that don't require new funding — just design changes to your food environment. USDA's **Smarter Lunchrooms Movement** (developed at Cornell University in collaboration with USDA) translated this research into practical guidance: move the salad bar to a higher-traffic location, put the least nutritious options at the end of the serving line, use descriptive names that make vegetables appealing ("zesty ginger carrots" increases selection compared to "carrots"), and offer smaller portions with free seconds on vegetables. These interventions have increased fruit and vegetable selection in school cafeterias by 20-30% in controlled studies with essentially no food cost increase.

USDA's **Team Nutrition** program (teamnutrition.usda.gov) provides free training materials, menu planning resources, and classroom nutrition education tools developed from this behavioral research. For child care centers specifically, USDA's **Child and Adult Care Food Program (CACFP)** meal pattern requirements set minimum nutrition standards; extensions resources help operators meet those standards while offering food children will actually eat.

For the 2025-2026 school year, coordinate with your district's **School Nutrition Director** on the latest USDA meal pattern requirements, which are periodically updated to align with the Dietary Guidelines for Americans. The 2025-2030 Dietary Guidelines (expected late 2025 or 2026) will eventually trigger updates to school nutrition standards — the standard pipeline from Dietary Guidelines → USDA school nutrition regulations → implementation typically takes 2-4 years.

**If you're a food company, dietitian, or registered nutritionist using USDA's nutrition data**: The **USDA FoodData Central database** (fdc.nal.usda.gov) is the authoritative reference for the nutrient composition of foods in the American food supply — maintained under the mandate of **7 U.S.C. § 3172**. This is the same database underlying most commercial nutrition analysis software, calorie-counting apps, and restaurant labeling systems. USDA continuously updates it as food formulations change and new nutrient data becomes available. If you find a gap or error in the database for a food you work with, USDA's **Nutrient Data Laboratory** at ars.usda.gov accepts data submission requests — particularly useful for novel ingredients, restaurant chain items, and reformulated products.

For industry stakeholders tracking the **Dietary Guidelines for Americans 2025-2030** (jointly published by USDA and HHS every five years): the advisory committee process is underway during a politically contentious period, with MAHA advocates pushing for stronger positions on ultra-processed foods, seed oils, and food additives than prior cycles. The Dietary Guidelines directly shape **USDA school nutrition meal patterns**, **WIC-approved food packages**, and **federal employee health programs** — and indirectly influence what food companies develop and market as "healthy." Industry trade associations track the DGAC process at dietaryguidelines.gov; public comment periods on the advisory report are the formal channel for input before the final guidelines are issued.

Registered dietitians and healthcare providers should also note the **What We Eat in America** survey (the dietary intake component of the federal NHANES health survey, jointly conducted by USDA and CDC/NIH) — this is the primary surveillance tool for understanding how Americans' actual diets compare to recommended patterns. Recent data showing extremely low fruit and vegetable consumption and high ultra-processed food consumption among lower-income Americans is driving both MAHA's agenda and advocates' push for stronger SNAP nutrition incentive programs.

## State Variations

EFNEP and the broader nutrition education program are delivered through state cooperative extension services, so the specific programs available in your state reflect your land-grant university's choices about curriculum, target populations, and delivery methods. States with large SNAP populations typically have larger programs. Extension programs can coordinate with state WIC agencies and county health departments to integrate nutrition education into a broader health service network.

## Pending Legislation

The 2025 Farm Bill (pending as of April 2026) is expected to reauthorize EFNEP and address the SNAP-Ed program structure. Nutrition education funding has been a perennial negotiation point in Farm Bill discussions, with advocates for low-income nutrition education pushing for funding levels that reflect inflation since the 1981 baseline year embedded in the funding formula.

## Recent Developments

- **MAHA agenda reshaping USDA nutrition research priorities — food additives, seed oils focus**: HHS Secretary Kennedy's "Make America Healthy Again" initiative has created cross-departmental pressure on USDA's nutrition research and extension programs. MAHA's concerns about food additives, seed oils, ultra-processed foods, and artificial dyes overlap with areas where USDA's Dietary Guidelines Advisory Committee and ERS food system research have historically taken more conservative positions. USDA Secretary Brooke Rollins and HHS Secretary Kennedy announced a joint food safety and nutrition review initiative in early 2025; the outcome of this review for USDA nutrition research and extension priorities is pending. USDA's Food and Nutrition Service (FNS), which administers SNAP and school nutrition programs, may face pressure to revise nutrition standards based on MAHA findings.
- **Dietary Guidelines 2025-2030 advisory process — politically contentious**: The 2025-2030 Dietary Guidelines Advisory Committee (DGAC) process — which informs HHS/USDA's official Dietary Guidelines issued every 5 years — is underway during a period of unusual political scrutiny. MAHA advocates have pushed for the DGAC to consider ultra-processed food consumption, seed oil health effects, and food additive safety — topics that prior DGACs addressed lightly. Industry lobbying by processed food, meat, and dairy sectors — which historically shapes the DGAC's recommendations — is intersecting with MAHA's counter-pressure. The final guidelines (expected late 2025 or 2026) will reflect these competing influences.
- **SNAP nutrition incentives — Gus Schumacher Nutrition Incentive Program (GusNIP) expansion**: The GusNIP program — which funds SNAP participant incentives to purchase fresh fruits and vegetables at farmers markets, grocery stores, and food co-ops — has expanded to a national network of over 600 programs in 50 states. GusNIP is one of the few USDA programs with robust evidence that increasing financial incentives improves dietary quality among low-income households. The 2023 Farm Bill extension maintained GusNIP funding; advocates have pushed for a funding increase in the next authorization. GusNIP is well-aligned with MAHA's emphasis on whole foods, making it potentially one of the USDA nutrition programs most likely to receive bipartisan support in the current political environment.
- **USDA's Human Nutrition Research Centers — network under budget pressure**: USDA's six Human Nutrition Research Centers (at Beltsville MD, Boston MA, Grand Forks ND, Houston TX, Davis CA, and Little Rock AR) conduct basic and applied nutrition research that feeds into dietary guidelines, food labeling policy, and nutrition education programs. These centers are funded through USDA's Agricultural Research Service budget; DOGE reviews of ARS spending have created uncertainty about all six centers' funding levels. Research at these centers on micronutrient requirements, dietary pattern effects on chronic disease, and children's nutritional needs is the scientific foundation for USDA's nutrition programs — cuts would create gaps in the evidence base for future Dietary Guidelines cycles.

President Trump signed the Whole Milk for Healthy Kids Act into law on January 14, 2026, allowing whole milk and reduced-fat (2%) milk to be served in federally funded school meal programs, reversing restrictions that had limited schools to low-fat and fat-free milk under prior USDA nutrition standards. The change directly affects USDA school nutrition program requirements, which are administered by the Food and Nutrition Service and grounded in Dietary Guidelines for Americans guidance. This represents a statutory override of the low-fat milk standard that had been in place since the Healthy, Hunger-Free Kids Act of 2010, and it predates the 2025–2030 Dietary Guidelines cycle rather than following from it. [USDA Press Release, January 15, 2026](https://www.usda.gov/about-usda/news/press-releases/2026/01/14/whole-milk-back-president-trump-signs-whole-milk-healthy-kids-act)

On January 8, 2026, USDA Secretary Brooke Rollins and HHS Secretary Robert F. Kennedy Jr. co-authored a joint op-ed in Fox News outlining a new dietary plan emphasizing whole, real foods for all Americans, signaling a coordinated cross-departmental nutrition policy direction under the MAHA initiative. The op-ed represents a public-facing articulation of the joint food safety and nutrition review initiative previously announced in early 2025, and suggests the review is producing concrete dietary guidance recommendations. The article's publication through USDA's Food and Nutrition Service newsroom indicates FNS is positioned as a key implementing agency for any resulting policy changes.

On September 24, 2025, USDA Secretary Brooke Rollins announced strengthened SNAP retailer stocking requirements under the MAHA initiative, requiring stores authorized to accept SNAP benefits to stock a greater variety of whole and minimally processed foods. The rule represents a concrete regulatory action flowing from the joint USDA-HHS food and nutrition review initiative, using SNAP retailer authorization standards as a lever to reshape the food environment for low-income shoppers. This is distinct from SNAP-Ed and EFNEP nutrition education efforts, instead targeting the supply side of what foods are available to SNAP participants at point of purchase. [USDA FNS Newsroom, September 24, 2025](https://www.fns.usda.gov/newsroom/usda-0223.25)

On September 10, 2025, USDA Secretary Brooke Rollins announced reinvigorated Farm to School grants aimed at connecting school meal programs with American farmers, directing federal nutrition education funding toward locally and regionally sourced food in school cafeterias. The grants are administered by USDA's Food and Nutrition Service and represent a concrete programmatic action linking agricultural supply chains to child nutrition goals. This initiative intersects with USDA's broader nutrition education and extension mission by reinforcing whole-food dietary patterns in federally funded school meal settings. [USDA FNS Newsroom, September 10, 2025](https://www.fns.usda.gov/newsroom/usda-0214.25)

On September 9, 2025, the MAHA Commission released a sweeping strategy document aimed at improving children's health, coordinated through USDA's Food and Nutrition Service as part of the broader Make America Healthy Again initiative. The report represents a formal commission-level output — distinct from the earlier joint op-ed and SNAP retailer stocking announcement — and signals a structured policy agenda with implications for USDA nutrition research, extension, and school nutrition programs. The strategy's release one day before the September 10, 2025 Farm to School grant announcement suggests coordinated rollout of MAHA-aligned nutrition initiatives across FNS programs. [USDA FNS Newsroom, September 9, 2025](https://www.fns.usda.gov/newsroom/usda-0213.25)

The President's FY2027 Budget request, released in April 2026, proposes a $510 million reduction to USDA's National Institute of Food and Agriculture (NIFA) formula grants—the funding mechanism that includes EFNEP and other land-grant university nutrition education and research programs—on the grounds that these grants function as "pre-determined earmarks for university pet projects" rather than competitively awarded research. The budget also proposes a 19 percent overall cut to USDA's discretionary budget authority, reducing it from approximately $25.7 billion to $20.8 billion for FY2027. These proposed reductions, if enacted, would directly affect the formula-based funding structure established under 7 U.S.C. § 3175 for EFNEP and related extension programs at 1862 and 1890 land-grant institutions. The budget proposal does not eliminate EFNEP by name but targets the formula grant mechanism through which it is funded.
