Can Healthy Cooking Classes for Seniors Slow Dementia and Diabetes? – Civil Eats
Harrel and Pratt wanted the option to pick truly fresh produce from their garden for their weekly class. So far, they’ve planted basil, cilantro, parsley, hot peppers, onions, butter lettuce, collard greens, strawberries, cherry tomatoes, and bell peppers.
Creating Food Access
Not all elders can access a community garden plot or have the energy to tend one. For many, simply getting to a grocery store with a variety of nutritious, affordable foods can be a challenge. California is home to the largest population of adults over 65 in the United States, but many who live on low incomes can’t meet their basic needs, increasing their risk of chronic illness and disease. The U.C. Davis Alzheimer’s Research Center received a $5 million grant from the state to ask, “What are the ways that we cannot only get older adults to exercise and diet, but what are the important differences in the way that Black Americans adopt healthy lifestyles and white Americans adopt healthy lifestyles?” Johnson explained. “Sometimes I call that the study of haves and have-nots.”
“I want to remain mobile. So what do you do? You eat right and you exercise.”
According to the Alzheimer’s Association, older Black Americans are twice as likely as older non-Hispanic white Americans to have Alzheimer’s or other dementias. Latinx Americans are about 1.5 times as likely. And women make up almost two-thirds of Americans living with the disease. Researchers at Columbia University’s Irving Medical Center have attributed the racial disparities to social and environmental factors, including chronic exposure to racism and unequal access to healthy food options. East Oakland is a prime example: Driving with Merrick from the East Oakland Sports Center to the a supermarket for a few red onions was a 2-mile one-way journey, which would have taken 45 minutes on foot or roughly 30 minutes by public transit, each way.
In addition to online classes, The Good Life provides free food, through pickups at the Sports Center to ensure participants get the ingredients they need for the recipes. Merrick says the number of food pickups has nearly doubled since the program started. The day before class, she and her team, including Spanish-language instructor Irma Hernandez, meet at the Sports Center to bag and package the week’s ingredients, usually sourced from a legendary local supermarket, the Berkeley Bowl. An hour later, women start trickling into the Sports Center lobby with reusable shopping bags and backpacks to pick up their ingredients, along with additional food—milk, eggs, vegetables, crackers, chips, and more—donated by the Alameda County Food Bank. During pickup hours, the lobby transforms from an echoey transactional space into a social scene. Many women linger to chat with each other and the staff, filling the air with warmth and laughter. They share cooking stories and catch up on each other’s lives.
Patricia Richard, an active 77-year-old who many credit with telling them about The Good Life, said she visits her neighborhood farmers’ market weekly, but still goes to the Sports Center for specific food items. “I want to remain mobile,” she said. “So what do you do? You eat right and you exercise.” A Good Life participant since it launched, Richard transitioned to a vegan diet a year and a half ago after learning she had partial artery blockage. “I decided that rather than taking drugs, I’ll just go with the diet.”

Despite the prevalence of dementia in the Black community, this group is underrepresented in research studies on preventing and treating the condition (though there are signs of improvement). Richard wanted to help researchers collect information “about Black people, about the discrepancies, and why we have so much dementia,” she said, so she joined U.C. Davis’ Alzheimer’s Disease Cohort, an ongoing study for which she undergoes a “grueling” 2.5-hour annual examination involving memory tests, blood work, and an MRI scan. Her involvement will continue for the rest of her life.
Forming Intergenerational Bonds
In the program’s first two years, Merrick personally delivered ingredients to Mattie Stevenson, an Oakland resident since the 1950s and the eldest participant in her class. When she spoke with me last year, Stevenson told me the cooking class had helped her manage diabetes and a heart condition by teaching her new ways to cook foods she loved and ones she had avoided, like cauliflower. Learning about new utensils provided a surprising benefit. “I just love the potato peeler,” she said. “It’s brought a joy to my life.”
“Loneliness is the most significant mental health issue facing older adults, no matter race, creed, or color—doesn’t matter. People want to be together.”
As this story was being reported, Stevenson passed away, at the age of 95. Merrick said she had come to think of Stevenson as family. On delivery days, the two would often sit on the porch and talk. That Stevenson’s son asked Merrick to speak at his mother’s funeral reflects the bond the two women formed in a relatively short time. “[Her passing] was devastating,” said Merrick. “It’s the hardest thing I’ve had to deal with since I’ve been doing this.” Not long before her death, The Good Life posted a promotional video on YouTube capturing Stevenson for a few moments at the center of the screen, a video that now also honors her memory.
For Johnson, the U.C. Davis psychologist, the power of social interaction and support is a critical facet of The Good Life. “Loneliness is the most significant mental health issue facing older adults, no matter race, creed, or color—doesn’t matter,” he said. “People want to be together.” He plans to publish a paper on his findings in the coming months; for now, he says the combination of maintaining a healthy, whole-foods diet and having a vibrant social life is our most effective defense against cognitive decline and dementia. As for the question he set out to answer about lifestyle differences: “Not all the data is analyzed,” he explained in an email, “but I can say with great certainty that Black Americans feel most at home and therefore most likely to adopt healthy lifestyles when other Black Americans from similar communities (what we call cultural congruence) lead the classes and comport themselves as unapologetically African American.”
