A new study suggests that antioxidants can help to reduce oxidative stress in men with prostate cancer. This follows additional research, which recently found that oxidative stress has a part to play in prostate cancer.
The researchers studied known biomarkers of oxidative stress in prostate tissue, blood and urine. Higher antioxidant intake was associated with a lower concentration of 8-isoprostane – a well-recognised marker for lipid peroxidation.
“The results of this study and others warrant additional research in humans on the mechanisms underlying the relationship between dietary antioxidants and prostate tissue redox status and carcinogenesis, as well as determining whether this relationship may influence disease severity, progression and recurrence.”
“This study demonstrated that intake of antioxidants was associated with less oxidative stress among men with incident prostate cancer.”
Antioxidant nutrients are found in rich supply in a Mediterranean style diet, particularly in brightly-coloured fruits and vegetables. The health benefits of a Mediterranean diet are well-studied, as are the benefits of a high intake of fruits and vegetables. This study adds to this body of evidence linking a healthy diet to reduced cancer risk.
