鱼油因其有益健康、抗抑炎症的功效而为人推捧。它被大力推荐用于协助减轻关节炎疼痛、预防癌症、减缓记忆衰退等。不过,最近的研究表明,鱼油或许并没有像广告宣传的那样具有神效,有时候好东西摄入太多也会过犹不及。

It’s been touted for its healthful, anti-inflammatory properties. It’s been recommended for helping ease the pain of arthritis, preventing cancer and slowing memory loss. But some recent studies of fish oil show that it may not always act as advertised—and that you can sometimes have too much of a good thing.

First, the latest news. Researchers spent 18 months following almost 300 patients with mild to moderate Alzheimer’s. Some took fish oil, others a placebo. And there was no difference cognitively between the two groups. The study is in the current Journal of the American Medical Association.

It’s a mixed bag on cancer. A study of more than 35,000 post-menopausal women found that those who took fish oil seemed half as likely to develop breast cancer as those who didn’t. That work was in the July issue of Cancer Epidemiology, Biomarkers & Prevention.

But a study in the October 15th issue of Cancer Research found that mice with inflamed bowels developed colitis and aggressive colon cancer when they were given high doses of fish oil.

So, fish oil might in fact have a healthful role in some circumstances. But you don’t want to swallow every fish story.
