A healthy diet may promote good health and reduce risk of major chronic diseases. Remember there is no absolute evidence showing the direct role of diet and nutrition in prostate cancer prevention.
Tomatoes are rich in an antioxidant known as lycopene. This antioxidant has a potential anticancer activity by inhibiting cell proliferation, arresting cell growth and increasing cell death in prostate cancer cells. Recent evidence suggested that dietary intake of lycopene was linked to a lower incidence of prostate cancer.
Cruciferous vegetables particularly broccoli and cauliflower contain high levels of an anticarcinogenic phytochemicals known as sulforaphane and indole-3 carbinol. These nutrients can protect cells from oxidative damage and induce apoptosis in damaged cells.
Green tea consumption has been associated with a reduced risk of prostate cancer. Polyphenols, which are found in green tea, appear to inhibit cancer cell growth and slow down the progression of prostate cancer.
Soy is a rich source of phytoestrogens (flavones, isoflavones and lignans). These naturally plant compounds have estrogen-like activity, which may reduce prostate cancer risk. Higher intake of soy products is believed to be one of the reasons for lower prostate cancer incidence amongst Asian men.
Cafestol and kahweol are components with well-known cancer-fighting abilities found exclusively in coffee. Increased consumption of regular or decaffeinated coffee is linked to a decreased risk of lethal prostate cancer. It is worth noting that high doses of caffeine can result in major health issues including irregular heartbeat and seizures.
