I came across this article today and wanted to know what you all thought about it. If I was the average American reading this, I would probably be inclined to lead toward a low-fat diet. What would you say to that person after they read this article?
"in men that ate a low-fat diet together with fish oil supplements for four to six weeks before prostate removal compared to men who ate a Western diet high in fat."
From the actual study:
"Patients undergoing radical prostatectomy were randomly assigned to receive a low-fat diet with 5 grams of fish oil daily (dietary omega-6:omega-3 ratio of 2:1) or a control Western diet (omega-6:omega-3 ratio of 15:1) for four to six weeks prior to surgery." http://www.ncbi.nlm.nih.gov/pubmed/22027686
In other words, there's no group for "men who ate a low-fat diet without fish oil supplementation" or for "men who supplemented fish oil while maintaining normal fat intake", and we cannot say which of the two interventions made the difference based on this study alone.
Also note that one can also achieve a lower n-6:n-3 ratio by replacing PUFA with saturated or monounsaturated fat, instead of carbs.
File this under "how to get the results you want".
