Update: ALA Not Associated with Prostate Cancer

I’m a bit late in adding this info to the Prostate Cancer section of Omega-3 Fatty Acid Recommendations for Vegetarians.

There has been a question as to whether the short-chain omega-3 fatty acid, alpha-linolenic acid (ALA), might cause prostate cancer as a few early studies suggested. But from 2004 to 2010 there were three meta-analyses not finding this to be the case. The 2010 meta-analysis I just added to the site found that subjects who consumed more than 1.5 g/day of ALA had a significantly decreased risk of prostate cancer (0.95, 0.91-0.99) compared to those who ate less.

    I updated it a bit. I don’t want that article to get too technical, so I didn’t provide many details.
