According to the American Cancer Society, prostate cancer is second most common disease after skin cancer among men. This form of cancer may put one out of five men at risk during his life time. Men most vulnerable to contract the disease are above 50 years of age and those who have a family history of prostate cancer.
Prostate is a part of the male reproductive system. To check if there is any problem with prostate, a blood test called prostate-specific antigen (PSA) is conducted. The high level of PSA means the prostate is inflamed, infected or enlarged. However, the test does not ensure existence for prostate cancer, for which a biopsy is performed to detect cancer.
It is not known if any kind of nutrition causes the disease, but there is a specific diet that can reduce the level of PSA. The diet could even have an ability to cure the cancer. Some research projects have indicated that vegetarian diet could offer protection against prostate cancer. Basically, fruits and vegetables which are red in color contain lycopene, a reddish pigment that gives color to fruit and vegetables like tomatoes, apricots, guavas, and watermelons.
Some studies have shown that Lycopene could reduce level of PSA and also risk of developing prostate cancer. Moreover, some other studies have shown that use of lycopene supplements is also helpful for some men. There may be other factors which might be preventing prostate cancer on eating such reddish vegetarian diet and these are number of other nutrient in the diet.
There is another source which could decrease the risk of developing prostate cancer: Vitamin D.
Vitamin D may also offer protection to prostate gland. It is still not known which source of vitamin D could help reduce the risk. Men diagnosed with prostate cancer often have low blood level of vitamin D.
