University of South Australia scientists have brought a potentially life-saving discovery for men worldwide.
Their recent research suggests that a diet rich in colorful fruits and vegetables can significantly reduce the risk of prostate cancer (PC).
These findings, published in the journal Cancers, emphasize the benefits of a Mediterranean or Asian diet, known for its abundance of such foods.
The study involved comparing prostate cancer patients and a healthy control group, focusing on the levels of various micronutrients in their blood.
Interestingly, men with prostate cancer had lower levels of certain key nutrients like lutein, lycopene, alpha-carotene, and selenium. In contrast, they had higher levels of iron, sulphur, and calcium.
One of the key findings was the link between low levels of lycopene and selenium in the blood and increased DNA damage following radiation exposure.
This suggests that these nutrients play a protective role, not only in preventing prostate cancer but also in aiding recovery among those undergoing radiation treatment.
Lycopene-rich foods include tomatoes, melons, papayas, grapes, peaches, watermelons, and cranberries. Conversely, Selenium is abundant in white meat, fish, shellfish, eggs, and nuts.
The study co-author, Dr. Permal Deo, recommends getting these nutrients directly from foods rather than supplements, as natural sources seem to be more effective.
Dr. Deo advises adopting a Mediterranean diet, with guidance from a dietitian, as the way nutrients are absorbed can vary greatly depending on several factors like the type of food, digestive system, individual genotypes, and possibly even gut microbiome.
This research is particularly significant as prostate cancer remains one of the most common and deadly cancers in men. Yet, the nutritional deficiencies linked to it are not widely known.
The study also reiterates that being overweight, tall, or having a diet high in dairy products and low in vitamin E might increase the risk of developing prostate cancer. Vitamin E is found in plant-based oils, nuts, seeds, fruits, and vegetables.
Ethnicity, family history, and age are other known risk factors for prostate cancer.
This research from South Australia is the first of its kind in the region to evaluate the relationship between micronutrient and trace element levels in the blood and the risk of prostate cancer.
In summary, this study highlights the potential of dietary choices in reducing the risk of prostate cancer. It encourages men to incorporate various colorful, nutrient-rich foods into their diets, potentially offering a simple yet effective way to combat this prevalent disease.
