Quick look
Senior nutrition programs are facing rising demand as the nation's older adult population rapidly expands, and a new Iowa State study shows training is becoming a critical tool to keep pace. Researchers report strong gains from a free online course that's helping early‑career staff build the policy, menu‑planning and operational skills the job requires.
AMES, Iowa - As the nation's older adult population climbs at one of the fastest rates in U.S. history, a new study from Iowa State University researchers points to a growing strain on the workforce responsible for feeding seniors - and a rising need for training.
The study, which was recently published in the Journal of Nutrition in Gerontology and Geriatrics, highlights the scale of the shift: The number of Americans age 65 and older rose from 43.1 million in 2012 to 57.8 million in 2022 - a 34% increase - and is projected to reach 88.8 million by 2060.
"We're watching the demographic landscape shift in real time, and the systems that support older adults have to keep pace," said study co-author Sarah Francis, Morrill professor of food science and human nutrition at Iowa State and a state specialist in food and health with Iowa State University Extension and Outreach.
Francis and her research team recently helped develop and evaluate a specific response to that need: the Instructional Campus on Aging Nutrition - or ican! - a free online training program created with the National Resource Center on Nutrition and Aging (NRCNA) to strengthen the skills of senior‑nutrition professionals. The NRCNA is funded through the Administration on Community Living and during this study, was managed through a collaborative partnership among the Iowa Department of Health and Human Services, Division of Aging and Disability Services, and Iowa State University.
"We saw overwhelmingly positive reactions across the board - engagement, relevance, satisfaction, knowledge, skills, attitudes and commitment," said Francis, whose team partnered with Iowa State Online on the program's educational design and technology.
"People weren't just watching the modules. They were using them."
Francis' co-authors on the study were Catherine Rudolph, a May 2026 graduate of Iowa State's Ph.D. program in nutritional science ("the study was part of her dissertation," Francis noted), and Eva Wood, who earned bachelor's and master's degrees in diet and exercise from Iowa State this spring.
Exposing structural vulnerabilities
The nationwide senior nutrition program, which is a core component of the Older Americans Act, delivers millions of meals annually through congregate dining sites, home‑delivered meals and nutrition education. But the workforce behind those services is increasingly early-career professionals, stretched and unevenly trained, the researchers found.
The NRCNA created the ican! course, which launched in 2024, after a nationwide needs assessment of 1,910 senior nutrition professionals identified gaps in business acumen, funding diversification, inclusive menu planning and understanding of Older Americans Act requirements.
"Of those survey respondents, 42.6% had two years of experience or less working in the senior nutrition field, and nearly half served rural regions, where staffing shortages and limited training access are persistent challenges," Francis said.
These numbers underscore a structural vulnerability: a growing reliance on early‑career workers who often enter the field with limited exposure to federal nutrition policy, menu standards or the operational demands of running meal programs for older adults, the researchers wrote.
Online training emerges as a scalable tool
The ican! course, which includes 10 modules that feature short videos, quizzes and supplemental resources, aims to help close this workforce training gap.
Francis and team surveyed approximately 800 senior nutrition professionals who had completed at least one ican! module and found these participants "showed strong agreement that the course improved their knowledge, confidence and ability to apply the material on the job," Francis said.
Nearly 90% said they planned to complete additional modules, she added.
The researchers also conducted interviews with a small group of respondents, who described using the training to onboard new staff, guide menu updates, strengthen food-safety practices and support organizational planning. Several said the course also helped clarify requirements under the Older Americans Act, which Francis said can be difficult to navigate without formal training.
"One participant told us (the ISU researchers) the videos were so clear that when she hires someone new, she simply points them to the modules," Francis said.
A system under pressure
Despite the positive reception, the ISU researchers noted in their findings that training alone cannot resolve the broader challenges facing senior nutrition programs.
"Some of the respondents we interviewed cited limited staffing, tight budgets and slow administrative processes as barriers to implementing new practices," Francis said. "They said adopting improvements - even when the course made the path forward clear - required approvals or resources their organizations lacked."
Others, Francis said, pointed to high turnover, which makes consistent training difficult.
The researchers said practical and accessible training like ican! can help stabilize a workforce that plays a critical role in helping older adults remain healthy and independent, but must be paired with broader investments in staffing and infrastructure to keep pace with the country's aging population.
"This is a system millions of older adults rely on every day, and strengthening the people behind it is how we keep it strong," Francis said. "We found a workforce that is motivated, adaptable and hungry for training. People want to learn, and they want to do this work well.
"That's a strong foundation to build on."
