Jim Grove, a blueberry enthusiast, has committed to consuming a cup of blueberries daily for the next year. He proudly shared, “I’m up to 35 pounds now, I think, in blueberries. That’s what I’ve eaten since the start,” as he prepared another blueberry smoothie at his residence in Halifax. Following a recent assessment session, where he underwent physical tests and answered various inquiries, Grove was handed a box of frozen Nova Scotia wild blueberries to last him the next two weeks.
Grove is participating in a novel study conducted by researchers at Dalhousie University’s faculty of medicine. This study aims to determine if a daily intake of blueberries, along with 30 grams of protein powder and personalized exercise routines thrice weekly, can enhance frailty and heart health in older individuals. The researchers anticipate that positive outcomes from the study may advocate for the prescription of blueberries by medical practitioners.
This study is part of a growing trend in Canada known as food prescribing. This approach involves doctors identifying patients facing food insecurity and at risk of diet-related chronic conditions and issuing them prescriptions for fresh, healthy foods. Leah Cahill, a registered dietitian leading the study named STRONG, emphasized the significance of prescribing lifestyle interventions to prevent illnesses.
Cahill’s team is actively recruiting participants for their clinical trial, which targets 240 individuals aged 65 and above. Half of the participants will consume blueberries daily, while the other half will maintain their regular diets. Regular assessments will be conducted over a year, with additional follow-ups scheduled for the subsequent year. The project received a $1-million grant from the River Philip Foundation to support transformative medical research initiatives.
Emphasizing the interconnection between frailty and heart health, Cahill stressed the importance of maintaining strength to combat cardiovascular diseases, a leading cause of mortality and disability in Canada. The initiative seeks to alleviate the burden on individuals by providing them with food and tailored exercise plans.
The concept of food prescribing is swiftly gaining traction across Canada, with a surge of interest from researchers. A recent commentary article highlighted the benefits of food prescribing in improving fruit and vegetable intake and managing chronic diseases. However, further research is warranted to assess its effectiveness and cost-efficiency relative to other healthcare and social programs.
As food prescribing initiatives emerge in various regions, including Guelph, Ontario, where clinicians have been prescribing fresh food akin to medication, the potential impact on public health remains a subject of ongoing debate. While such programs have shown positive outcomes, funding sustainability remains a concern. Advocates are pushing for government investment to establish a provincial food prescription program.
In conclusion, the STRONG study and similar initiatives underscore the evolving landscape of healthcare interventions, where food prescribing is emerging as a promising strategy to promote healthy living and prevent chronic ailments. Groove, reflecting on his journey towards improved health through blueberries and exercise, is optimistic about the long-term benefits of his lifestyle changes.
