Question: I'm at risk for both macular degeneration and Alzheimer's disease, according to my doctors. I've read articles about omega-3 oils saying that more EPA than DHA is good for macular degeneration, and the reverse is true for Alzheimer's. What do you recommend?
Answer: The answer is simple: eat fish (preferably oily fish) at least twice a week. Although we can certainly tell you which fish oil supplements (or other omega-3 supplements) are best for providing EPA and/or DHA, our analyses of the clinical literature show that, for both age-related macular degeneration (AMD) and Alzheimer's disease, supplements have generally not been beneficial, while regular consumption of fish is associated with benefits. Only if you won't or can't eat fish at least twice a week might fish oil supplements be helpful for these conditions.
