Omega-3 helps inhibit prostate cancer

Prostate cancer can be life-threatening if tumor cells spread and invade other tissues, such as bone marrow. Laboratory tests found that omega-3 contained in fish fat prevented this.

Researchers at Paterson Institute in Manchester, England, tested the effect of two dietary fats on prostate cancer cells. Previous studies have found that omega-3 fats in mackerel and tuna help reduce the risk of cancer - and some other diseases like heart disease. Omega-6 fats, found in vegetable oils, nuts and seeds, also play a major role in keeping people healthy. However, while omega-6 fats increase the spread of prostate cancer cells to the bone marrow, omega-3 fats inhibit this.

Researchers believe that tumor cells use omega-6 fats as an energy source, while omega-3 fats appear to interfere with this process in some way. Researcher Noel Clarke said: 'The omega-3 and omega-6 fat-balanced diet can help keep cancer in the prostate, where it is controlled safely or easier to treat than surgery or radiation therapy '.
