Community gardening could play an important role in preventing cancer and mental health disorders – News-Medical. Net
Get more exercise. Eat right. Make new friends.
As we compile our lists of resolutions aimed at improving physical and psychological health in 2023, brand new CU Boulder research suggests one addition could have a powerful impact: Gardening.
Funded by the American Cancer Society, the first-ever, randomized, controlled trial associated with community gardening found that those who started gardening ate more fiber and got more bodily activity-; two known ways to reduce risk of malignancy and chronic diseases. They also saw their levels of stress and anxiety significantly decrease.
The findings were published Jan. 4 within the journal Lancet Planetary Health .
These findings provide concrete evidence that community gardening can play an essential role inside preventing cancer, chronic diseases and mental health problems. ”

Filling the particular research gap
Litt has spent much of her career seeking to identify affordable, scalable and sustainable ways to reduce disease danger, especially among low-income communities.
Gardening seemed an ideal place to start.
“No matter where you go, people say there’s just something about gardening that makes them feel better, ” said Litt, who is also a researcher with the Barcelona Institute for Global Health.
But solid science on its benefits is hard to come by. Without proof, it’s difficult to get support for new programs, she said.
Some small observational studies possess found that will people who garden tend to eat more fruits plus vegetables and have a healthier weight. But it has been unclear whether healthier people just tend to garden, or horticulture influences health.
Only three studies have applied the gold standard of scientific research, the particular randomized managed trial, in order to the pastime. None have got looked specifically at local community gardening.
To fill the gap, Litt recruited 291 non-gardening adults, average age of 41, from the Denver area. More than a third were Hispanic and more than half came from low-income households.
After the last spring frost, half had been assigned to the community gardening group and half to a control group that was asked to wait one year to start gardening.
The particular gardening team received the free neighborhood garden plot, some seeds and seedlings, and an introductory growing plants course through the nonprofit Denver Urban Gardens program and a study partner.
Both groups took periodic surveys regarding their nutritional intake plus mental wellness, underwent body measurements and wore activity monitors.
A fiber boost
By fall, those in the gardening group were eating, on average, 1 . 4 grams a lot more fiber per day than the control group-; an increase of about 7%.
The authors note that dietary fiber exerts a profound effect on inflammatory and immune responses, influencing everything from how we metabolize food in order to how healthy our gut microbiome is to how susceptible we are to diabetes and certain cancers.
While doctors recommend about 25 to 38 grams of fiber per day, the average adult consumes less than 16 grams.
“An increase associated with one gram of fiber can have got large, positive effects about health, ” said co-author James Hebert, director of University associated with South Carolina’s cancer prevention and control program.
The gardening group also increased their physical activity levels by about 42 minutes per week. Public health agencies suggest at least 150 minutes of physical exercise for each week, the recommendation only a quarter of the U. S. population meets. With simply two to three visits to the particular community backyard weekly, participants met 28% of that requirement.
Study individuals also saw their stress and anxiety levels decrease, with those who came into the study most stressed plus anxious seeing the greatest reduction in psychological health issues.
The study also confirmed that even novice gardeners can reap measurable health benefits associated with the activity in their own first season. As they have more experience and enjoy greater yields, Litt suspects such benefits will increase.
The particular study results don’t surprise Linda Appel Lipsius, executive director of Denver Urban Gardens (DUG), a 43-year-old nonprofit that helps about 18, 000 people each year grow their particular own food in community garden plots.
“It’s transformational, even life-saving, for so many people, ” Lipsius said.
Many DUG participants live in areas where access to inexpensive fresh fruits and vegetables is otherwise extremely limited. Some are low-income immigrants now living in apartments-; having a garden storyline allows them to grow food from their home country and pass on traditional recipes to their family and neighbors.
The social connection is also huge.
“Even if you come to the garden looking to develop your meals on your own in a quiet place, you begin to look at your own neighbor’s plot and share techniques and recipes, and over time relationships bloom, inch said Litt, noting that while gardening alone is good for you, gardening in community may have additional advantages. “It’s not just about the fruits and vegetables. It’s also about being within a natural space outdoors together with others. ”
Litt said the girl hopes the particular findings will encourage health professionals, policymakers plus land planners to look to local community gardens, and other spaces that encourage people in order to come together inside nature, as a vital part associated with the public health system. The evidence is clear, the lady said.
Researchers from your Colorado School of Public Wellness, Colorado State University plus Michigan Condition University furthermore contributed to this study.
