The false promise of fish oil

24 Jul

I have been blogging a lot about diet lately and I should move onto other topics, but I think this Washington Post story is important:

“People in the United States spend about $1.2 billion annually for fish oil pills and related supplements even though the vast majority of research published recently in major journals provides no evidence of a health benefit.”



More evidence against fish oil

14 Apr

A good review in The New York Times:

“There’s a major disconnect,” Dr. Grey said. “The sales are going up despite the progressive accumulation of trials that show no effect.”

Here is Dr. Greger on the topic:

‘Put all the studies together, and there’s no justification for the use of omega 3s as a structured intervention in everyday clinical practice or for guidelines supporting more dietary omega-3’s. So what should doctors say when their patients follow the American Heart Association advice to ask them about fish oil supplements? Given this and other negative meta-analyses, “our job as doctors should be to stop highly marketed fish oil supplementation in all of our patients.”’


Krill oil shortens mouse life span

Beware of the claims made on behalf of the various fish oil products. Here is a recent study suggesting that krill oil (a popular fish oil supplement) shortens the life span of mice. From the abstract:

“Taken together, the results do not support the idea that the consumption of isolated ω-3 fatty acid-rich oils will increase the life span or health of initially healthy individuals.”


Dr. Greger: Fish oil is snake oil

In Dr. Greger’s latest evaluation of fish oil he states:

“Advice to eat oily fish or take fish oil to lower risk of heart disease, stroke, or mortality is no longer supported by the balance of available evidence.”
