Dietary intake and prostate cancer, continued pursuit for evidence

The potential for diet to impact the risk and/or progression of prostate cancer (PCa) has inspired many research studies. Preclinical and human studies have examined the effect on PCa of nutrients and dietary factors including fat, protein, carbohydrate, fiber, vitamins, minerals and phytonutrients. Specific foods such as pomegranate, green tea, tomatoes and dietary patterns such as the Mediterranean and low carbohydrate ketogenic diets have also been examined in limited studies. Overall, some have shown a potential effect, however, most lack the confirmation by randomized controlled trials (RCT) in humans and thus the findings remain inconclusive (1)
