One out of six men will be diagnosed with prostate cancer during their lifetime. High grade prostate cancer is dangerous and can kill. In the United States, more than 200,000 new cases are diagnosed every year - leading to 31,000 deaths. Fortunately, there is a lot you can do to prevent prostate cancer naturally.

Here are five scientifically proven tips that will help you protect your prostate health:

Increase your intake of omega-3s. Increasing your intake of long-chain omega-3 polyunsaturated fatty acids may protect you from prostate cancer. A study led by John S. Witte at the University of California has shown that men, who ate dark fish such as salmon one or more times per week, had a 63 percent lower risk of developing an aggressive form of prostate cancer than those, who ate it rarely.

Eat walnuts and pomegranates. Ongoing research suggests that men should eat pomegranates and walnuts as part of a prostate-healthy diet. These two superfoods contain specific types of compounds that have the ability to reduce the size and growth of prostate cancer. Phenylpropanoids and flavones present in pomegranates prevent prostate cancer cells from interacting with testosterone and spreading to other parts of the body. The compounds present in walnuts were linked to a 30 percent slower growth of the disease and 50 percent smaller tumors in mice that were genetically programmed to develop prostate cancer.

Drink coffee and green tea. The antioxidants and other biologically active natural compounds of coffee and green tea are believed to play a significant role in the prevention and treatment of prostate cancer. For example, recent studies have indicated that Polyphenol E - one of the active ingredients present in green tea - can reduce levels of PSA (Prostate Specific Antigen), which is an indicator of disease severity in prostate cancer patients.

Lower your cholesterol levels. A study performed by Johns Hopkins scientists suggests that men whose cholesterol levels are below 200mg/dL have an almost 60 percent lower chance of suffering from an aggressive type of prostate cancer. You can reduce your cholesterol levels with regular exercise, weight loss and healthy diet.

Get enough vitamin D. We still have a lot to learn about the "sunshine vitamin", but UK researchers hypothesize that vitamin D can be an effective treatment for prostate cancer - reducing PSA level by as much as half in 20 percent of patients. "This is a treatment which is unlikely to have significant toxicity and is a welcome addition to the therapeutic options for patients with prostate cancer", says Professor Jonathan Waxman from Imperial College London.

In the United Kingdom, one man dies every hour from the prostate cancer. It is also the second leading cause of cancer death in American men. In order to save more lives, it is needed to raise awareness of the possible ways to prevent prostate cancer naturally.
