Gardening can help reduce cancer risk, boost mental health: Study

While getting more exercise, eating right, and making new friends are all good habits, new CU Boulder research suggests the addition of gardening can have a powerful impact.

Funded by the American Cancer Society, the first-ever, randomized, controlled trial of community gardening found that those who started gardening ate more fiber and got more physical activity--two known ways to reduce the risk of cancer and chronic diseases. They also saw their levels of stress and anxiety significantly decrease. The findings were published in the journal Lancet Planetary Health.


"These findings provide concrete evidence that community gardening could play an important role in preventing cancer, chronic diseases, and mental health disorders," said senior author Jill Litt, a professor in the Department of Environmental Studies at CU Boulder.

Filling the research gap

Litt has spent much of her career seeking to identify affordable, scalable, and sustainable ways to reduce disease risk, 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 evidence, it's hard to get support for new programs, she said.

Some small observational studies have found that people who garden tend to eat more fruits and vegetables and have a healthier weight. But it has been unclear whether healthier people just tend to garden or whether gardening influences health.

Only three studies have applied the gold standard of scientific research, the randomized controlled trial, to the pastime. None have looked specifically at community gardening.

To fill the gap, Litt recruited 291 non-gardening adults, an 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 were assigned to the community gardening group and half to a control group that was asked to wait one year to start gardening.

The gardening group received a free community garden plot, some seeds and seedlings, and an introductory gardening course through the nonprofit Denver Urban Gardens program and a study partner.

Both groups took periodic surveys about their nutritional intake and mental health, underwent body measurements, and wore activity monitors.

A fibre boost

By fall, those in the gardening group were eating, on average, 1.4 grams more fibre per day than the control group--an increase of about 7 per cent.

The authors note that fibre exerts a profound effect on inflammatory and immune responses, influencing everything from how we metabolize food 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 fibre per day, the average adult consumes less than 16 grams.

"An increase of one gram of fibre can have large, positive effects on health," said co-author James Hebert, director of the University of 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 recommend at least 150 minutes of physical activity per week, a recommendation only a quarter of the U.S. population meets. With just two to three visits to the community garden weekly, participants met 28 per cent of that requirement.

Study participants also saw their stress and anxiety levels decrease, with those who came into the study most stressed and anxious seeing the greatest reduction in mental health issues.

The study also confirmed that even novice gardeners can reap measurable health benefits of the pastime in their first season. As they have more experience and enjoy greater yields, Litt suspects such benefits will increase.

Blooming relationships

The 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 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 affordable fresh fruits and vegetables is otherwise extremely limited. Some are low-income immigrants now living in apartments--having a garden plot allows them to grow food from their home country and pass on traditional recipes to their family and neighbours.

The social connection is also huge.

"Even if you come to the garden looking to grow your food on your own in a quiet place, you start to look at your neighbour's plot and share techniques and recipes, and over time relationships bloom," said Litt, noting that while gardening alone is good for you, gardening in the community may have additional benefits. "It's not just about the fruits and vegetables. It's also about being in a natural space outdoors together with others."

Litt said she hopes the findings will encourage health professionals, policymakers and land planners to look to community gardens, and other spaces that encourage people to come together in nature, as a vital part of the public health system. The evidence is clear, she said.

Heavier bleeding and iron loss linked to long Covid in women, study finds

Highlights:

  • Survey of more than 12,000 UK women finds heavier, longer periods linked to long Covid
  • Symptom severity rises and falls across the menstrual cycle, worsening during periods
  • Tests reveal inflammation in womb lining and hormonal changes, but no damage to ovaries
  • Iron deficiency risk may exacerbate fatigue, dizziness and other common long Covid symptoms

Study highlights link between long Covid and menstrual changes

Women with long Covid are more likely to experience longer and heavier periods, putting them at increased risk of iron deficiency, researchers have found. The findings come from a UK survey of more than 12,000 women, which also showed that the severity of long Covid symptoms fluctuated across the menstrual cycle and often worsened during menstruation.

Findings from UK survey

Between March and May 2021, 12,187 women completed an online survey. Of these, more than 1,000 had long Covid, over 1,700 had recovered from the virus, and 9,400 had never tested positive. The study revealed that women with long Covid reported heavier and longer periods, as well as more frequent bleeding between cycles, compared with other groups.

Bradford’s first curry house traced back to 1942 ahead of World Curry Festival

Highlights:

  • Research for the World Curry Festival uncovered evidence of a curry house in Bradford in 1942.
  • Cafe Nasim, later called The Bengal Restaurant, is thought to be the city’s first.
  • The discovery coincides with Bradford’s City of Culture celebrations.
  • Festival events will include theatre, lectures, and a street food market.

Historic discovery in Bradford’s food heritage

Bradford’s claim as the curry capital of Britain has gained new historical depth. Organisers of the World Curry Festival have uncovered evidence that the city’s first curry house opened in 1942.

Documents revealed that Cafe Nasim, later renamed The Bengal Restaurant, once stood on the site of the current Kashmir Restaurant on Morley Street. Researcher David Pendleton identified an advert for the cafe in the Yorkshire Observer dated December 1942, describing it as “Bradford’s First Indian Restaurant”.

Global warming may drive higher consumption of sugary drinks and ice cream, study warns

Highlights:

  • Hotter days linked to greater intake of sugary drinks and frozen desserts
  • Lower-income households most affected, research finds
  • Climate change could worsen health risks linked to sugar consumption
  • Study based on 15 years of US household food purchasing data

Sugary consumption rising with heat

People are more likely to consume sugary drinks and ice cream on warmer days, particularly in lower-income households, according to new research. The study warns that climate change could intensify this trend, adding to health risks as global temperatures continue to rise.

Sugar consumption is a major contributor to obesity, diabetes, and cardiovascular disease, and has surged worldwide in recent decades. The findings, published in Nature Climate Change, suggest that rising heat could be nudging more people towards high-sugar products such as soda, juice and ice cream.
