Most of that work is directed at children, who make up three-quarters of the United States' SNAP participants.
In West Virginia, educators with SNAP-Ed visit schools where at least 50 percent of students receive free or reduced meals.
Their lessons, which are structured to comply with state Board of Education content standards, help introduce children to healthy foods like fruits, vegetables and whole grains. Educators also seek to encourage better eating behaviors, as well as physical activity.
SNAP-Ed also provides nutrition education services outside of the school year, talking with children at day camps and other programs.
The adult side of the program, operated through WVU's extension services, hosts workshops in low-income communities around the state, helping residents learn how to stretch their monthly food budgets.
Gannon said West Virginia's SNAP-Ed staffers reach about 20,000 children each year, along with several thousand adults.
"It's a shame to cut services that will benefit the long-term health and productivity of that group of children," she said.
According to the nonprofit Public Health Institute, each dollar spent on nutrition education could save as many as $10 in future healthcare costs.
Gannon said the West Virginia SNAP-Ed program will be able to sustain its programs for right now, but that won't last if Congress decides to cut the its budget again.
"You can maintain for a while but after time, as cuts continue to get deeper and deeper, you have to cut services," she said.
She said cutting services means the program will hire fewer people and, as a result, reach fewer SNAP participants.
