Omega-6 promotes prostate cancer

A new study reveals a significant relationship between the amount of omega-6 acids in a man's diet, and the increased risk of developing prostate cancer. In a study conducted at the San Francisco VA Medical Center, human prostate tumors grew twice as quickly when omega-6 acids were introduced into cell cultures.

Omega-6 acids are commonly found in corn oil. In the average American diet, omega-6 rich oils are consumed at levels 25 times greater than the consumption of beneficial oils. Healthy oils are canola oil, olive oil and fish oil. Over the last 60 years, prostate cancer diagnosis has risen at the same levels as the increased usage of omega-6 foods.

In the study, the researchers were interested in discovering how, and why, omega-6 acids affected prostate tumor growth. The researchers were able to determine that omega-6 signals the activation of a dozen inflammatory genes known to be important to cancer growth.
