South Australia Üniversitesi araştırmacıları tarafından yapılan iki araştırmaya göre, düzenli olarak çeşitli renkli meyve ve sebzeleri tüketen erkeklerin prostat kanserine yakalanma riski daha düşük. Bu çalışmalar, bir dizi mikro besin içeren bir Akdeniz veya Asya diyetinin prostat kanserini önlemeye ve hastalık için radyasyon tedavisinden kurtulmaya yardımcı olabileceğini buldu. Araştırma, likopen ve selenyum gibi bazı mikro besinlerin düşük düzeylerinin, radyasyona maruz kaldıktan sonra artan prostat kanseri riski ve artan DNA hasarı ile ilişkili olduğunu gösterdi.
Gökkuşağı meyve ve sebze prostat kanserine karşı en iyi korunmadır.
University of South Australia bilim adamlarının yaptığı yeni araştırmaya göre, düzenli olarak renkli meyve ve sebzeleri tüketen erkeklere prostat kanseri (PC) teşhisi konma olasılığı daha düşük.
Belirli mikro besinler açısından zengin bir gıda gökkuşağı, prostat kanserini (PC) önlemeye ve hastalık için radyasyon tedavisi gören erkekler arasında iyileşmeyi hızlandırmaya yardımcı olur.

Araştırmacılar mikro besinleri karşılaştırdı[{” attribute=””>plasma concentrations of prostate cancer patients with a healthy control group, revealing low levels of lutein, lycopene, alpha-carotene, and selenium in PC patients and high levels of iron, sulfur, and calcium in the same group, relative to controls.
Increased DNA damage after radiation exposure was also associated with low lycopene and selenium in blood plasma.
Men with plasma concentrations lower than 0.25 micrograms (ug) per milliliter (mL) for lycopene and/or lower than 120ug/L for selenium have an increased risk of prostate cancer and are likely to be more sensitive to the damaging effects of radiation.
Foods that are rich in lycopene include tomatoes, melons, papayas, grapes, peaches, watermelons, and cranberries. Selenium-rich foods include white meat, fish, shellfish, eggs, and nuts.
Study co-author Dr. Permal Deo says eating foods that are naturally rich in lycopene and selenium is preferable to taking supplements, where the benefits are limited, according to previous studies.
“Our recommendation is to adopt a Mediterranean diet enlisting the help of a dietician because people absorb nutrients in different ways, depending on the food, the digestive system, the person’s genotype, and possibly their microbiome,” Dr. Deo says.
Prostate cancer remains one of the most common and fatal cancers in men, but the nutritional deficiencies associated with it remain largely unknown, hence this study.
Other risk factors, such as ethnicity, family history, and age have previously been linked to prostate cancer.
“There is strong evidence that being overweight and tall increases the risk of prostate cancer. Diets high in dairy products and low in vitamin E may also increase the risk but the evidence is less clear.”
Vitamin E is found in plant-based oils, nuts, seeds, fruits, and vegetables.
The research is the first to evaluate plasma concentrations of micronutrients and trace elements with respect to prostate cancer in the South Australian population.
