     Summary:   
         New research shows that men who stick to a predominantly   
         Mediterranean diet are less likely to be diagnosed with prostate   
         cancer. This diet also improves their chances of recovery if they   
         have PC and are undergoing radiation treatment.

   ==========================================================================   
   Men who consume colourful fruits and vegetables on a regular basis are   
   less likely to be diagnosed with prostate cancer (PC), according to new   
   research by University of South Australia scientists.   
      
      
   ==========================================================================   
   A rainbow of foods rich in certain micronutrients helps to prevent   
   prostate cancer (PC) as well as speed up recovery among men who undergo   
   radiation treatment for the disease.   
      
   The findings, from two studies published in the journal Cancers,highlight   
   the importance of a Mediterranean or Asian diet that includes these foods.   
      
   Researchers compared micronutrient 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, sulphur, 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   
   millilitre (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.
