Charles Humphrey doesn’t just deliver groceries — he delivers dignity. Every week, the FreshFix driver pulls up to apartment buildings across Buffalo with boxes of fresh carrots, leafy greens, and ripe tomatoes, handing them directly to older adults who once struggled to afford or access healthy food. "He’s kind, he’s respectful, he remembers our names," one participant said. This human touch is part of what made a new University at Buffalo study so powerful — and so promising.
In the U.S., millions of older adults face food insecurity, meaning they don’t always know where their next meal will come from. Food prescription programs aim to fix that by giving people vouchers for free fruits and vegetables. But for years, a big problem has remained: most people never use them. Past research shows only 9% to 18% of vouchers are redeemed. Why? Many lack transportation, feel embarrassed using aid, or find markets hard to reach.
The UB study tested a simple but powerful idea: what if the food came to them? Researchers worked with 67 adults, mostly Black and over 65, recruited from clinics at Erie County Medical Center. One group got weekly boxes of fresh produce delivered to their door. Another received meal kits with ingredients for three recipes. A third, the control group, got the usual — vouchers for a mobile market.
The results were striking. Nearly 90% — 89.2% to be exact — of those who received home deliveries actually used the food. In the voucher group, only 28.3% redeemed their benefits. "We wanted to overcome those barriers," says Dr. Lucia A. Leone, the study’s lead researcher. "We wanted to find out, does delivery improve redemption? The answer is yes."
Customization helped too. People could choose what went into their boxes, making the service feel personal, not transactional. Surprisingly, the meal kits didn’t increase produce use — most participants already knew how to cook. But they did improve food security simply by providing more food. And the delivery driver? He wasn’t just a courier. Participants gave the program over 9 out of 10 in satisfaction and often praised Humphrey by name. "That connection with one person," Leone says, "can really improve the success of the program."
This study, published in Frontiers in Public Health, offers a clear lesson: when it comes to helping older adults eat better, convenience and respect matter as much as the food itself. As food insecurity continues to affect millions, solutions like home delivery — simple, human, and effective — may be exactly what the doctor ordered.
