摘要:The hypothesis is that the lack of natural phytochemicals in the diet of the men in the West contributes to the higher incidence of prostate cancer, as compared to the rest of the world. There is strong evidence in the literature that phytochemicals play the role of a defense system in a human body so that the body is not as vulnerable to incurable and dangerous diseases. There have been studies that show phytochemicals play a major role in the prevention of cancer and fewer studies specifically on prostate cancer. Health benefits are best obtained through the consumption of a varied diet that comprise fruits and vegetables, grains, legumes and seeds which contain the phytochemicals. The current work has shown the perspective that some common foods that contain high amounts of phytochemicals which could be key to good health (as regards not getting prostate cancer) include garlic, onion, coriander, cumin, chili peppers and turmeric, as well as the almost universal food items of vegetable oil, onions and black pepper. The current paper has shown the perspective that the large incidences of prostate cancer in the USA, Canada, several western European nations, Australia and New Zealand are probably due to the lack of active phytochemicals in the daily diet of the majority of the men in these countries.
