Gee, look! Here's a report from the L.A. Times that yet another study has found that fish oil supplements (and, by extension, vegan omega-3 supplements) are of no benefit to people with preexisting heart disease in avoiding future problems. You can read the entire article here. I was, however, perplexed by these two paragraphs toward the end of the article. Speaking of the authors of the study, the article says,
Still they note that there’s “no conclusive evidence” for recommending fish oil to prevent a first or subsequent heart attack.
But that doesn’t mean, they add, that doctors should stop recommending oily fish to their patients.
What other benefit might there be to eating oily fish? Dioxin, mercury, endothelial cell damage?
Then there's this article from Yahoo News about a Japanese study linking regular seaweed consumption with thyroid cancer in post-menopausal women. Perhaps, as Jeff Novick suggests, the safest thing is just to get our greens from the land.
