Yes and no: The evidence that suggests there is a protective effect from fish oil against alzheimer's is weak and tentative. I wouldn't take it for that indication. While we're at it, the link showing reduced heart disease is weak too. The strong link is eating fish. Your salmon is good.

Dr. Werner is correct, and I'm also totally unimpressed with the new claim about a link to prostate cancer. Especially when the claim makes no sense biologically, look for a confounding variable. Perhaps people who take fish oil capsules / eat fish are more health conscious, go to the doctor more, and get prostate cancer diagnosed more often. Generally, be skeptical about "health news items" that show correlations that don't make sense -- they're generally not a good guide to planning your life. Enjoy eating your salmon for its own sake.
