The rise of food as medicine

In foodservice businesses — and particularly in dining rooms within senior-living communities — the concept of food as medicine is transforming dining programs. Increasingly, research is proving that food is a form of medicine, working alongside exercise and traditional therapies to dramatically improve health outcomes and longevity. Operators that design menus with these outcomes in mind can transform their guests’ health.
It’s well known that a predominantly whole-food, plant-based diet rich in vegetables, fruits, whole grains, legumes, nuts, and seeds offers substantial protective benefits. But the typical American diet includes 60 percent ultra-processed foods, according to Stanford Medicine. Small swaps of healthier ingredients in place of ultra-processed items can make a big difference.
In a recent podcast interview, Mayo Clinic lifestyle medicine specialist Dr. Dawn Mussallem shared how significant those benefits can be. For example, in one large cohort of breast cancer survivors, those who followed a high-fiber, low-sugar, plant-forward “diabetes-risk-reduction diet” experienced a 33 percent improvement in overall survival and a 17 percent improvement in breast-cancer-specific survival. Specific foods also showed strong effects: consuming two cups of leafy greens daily and regular intake of cruciferous vegetables improved survival, while eating two servings of berries per week was linked to a 25 percent reduction in breast-cancer-specific mortality.
Overall, people who increase their intake of fruit and vegetables see significant improvements in health outcomes across a variety of conditions, regardless of age. Mussallem said research has found that people who eat five servings of fruit and vegetables per day (versus two) had a 10 percent reduction in dying from cancer, a 12 percent reduction in dying from heart disease, and a 35 percent reduction in dying from respiratory disease. Even cases of COVID have been impacted by these diets: Studies from 2023 and 2024 found that higher adherence to healthy plant-based diets was linked to a 39 percent lower likelihood of contracting COVID-19 and a 59 percent lower chance of hospitalization from the illness.
Senior living providers are integrating this science into practice. Many communities are shifting toward plant-forward menus that limit processed meats, include colorful vegetables, and integrate “longevity foods” such as berries, beans, and whole grains. Others are adapting resident-submitted family recipes into healthier, whole-food versions that preserve comfort and cultural connection. Some operators are offering culinary-medicine demonstrations, helping residents understand how everyday ingredients influence inflammation, cognition and chronic-disease risk.
Importantly, these foods are presented as delicious, not restrictive, options. By adopting a food-as-medicine model, foodservice operators can provide meals that are measurable contributors to residents’ wellbeing, longevity, and quality of life.
