Healthy diets and probiotics may slow tumor growth in cancer patients, according to recent research findings. A study involving prostate cancer patients showed that supplements containing vegetables like broccoli, turmeric, and pomegranate, along with a probiotic containing Lactobacillus, led to a decrease in prostate-specific antigen (PSA) levels in the blood, which is an indicator of disease progression. This study, led by Professor Robert Thomas from the University of Bedfordshire, demonstrated improvements in urinary symptoms and overall health in men.
Probiotics, which are live bacteria and yeasts known for their health benefits, play a role in restoring the natural balance of gut bacteria. The microbiome, the ecosystem of microorganisms in the stomach and intestines, can be disrupted by illness, medication, or a poor diet lacking fresh, whole foods. Maintaining a healthy balance of gut bacteria is essential for overall health and immune function.
The trial, conducted by a team from the University of Bedfordshire, Cambridge University Hospitals, and Bedford Hospital in collaboration with experts from the US and Australia, involved 212 men with low-risk prostate cancer. Participants were given a vegetable-rich supplement high in phytochemicals, which have antioxidant, anti-inflammatory, and anticancer properties. The study revealed a significant slowing of PSA progression in both groups, with a more pronounced effect in the group receiving the probiotic.
Published in the European Urology Oncology journal, the study reported that a higher percentage of men taking the supplement and probiotic combination had stable disease or even experienced disease regression compared to those taking the supplement and a placebo. Dr. Jeffrey Aldous from the University of Bedfordshire highlighted the potential of targeted dietary strategies in influencing the gut microbiome to benefit cancer markers and overall well-being.
Dr. Hayley Luxton from Prostate Cancer UK noted the promising implications of the study in linking diet and gut health to prostate cancer outcomes. While further research is needed to fully understand the role of probiotics and supplements, maintaining a balanced and healthy diet is recommended for overall health and well-being.
