"I recommend taking small amounts of fish oil and flax seed oil -- 2 grams per day of each -- to provide the omega-3 fatty acids without taking extra omega-6 fatty acids. The only exception is for men who have prostate cancer or who are at risk for it. Dr. Charles Myers at the University of Virginia Medical School has evidence indicating that flax seed oil may promote (about a 300% increase) the growth of prostate tumors. Someone with prostate cancer should avoid flax seed oil and instead take 2-3 grams per day of fish oil."
