It’s been ____1____ 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 ____2____.
First, the latest news. Researchers spent 18 months following almost 300 patients with ____3____ 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 ____4____ 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 ____5____.

對魚油的研究發(fā)現(xiàn)食用效果好壞參半 魚油因其有益健康、抗抑炎癥的功效而為人推捧。它被大力推薦用于協(xié)助減輕關(guān)節(jié)炎疼痛、預(yù)防癌癥、減緩記憶衰退等。不過，最近的研究表明，魚油或許并沒有像廣告宣傳的那樣具有神效，有時候好東西攝入太多也會過猶不及。 首先，最新消息：研究人員花落18個月來追蹤近300名輕度至中度的阿茲海默癥患者。其中一些人服用魚油，另一些服用安慰劑。而兩組對照并無認知差異。這項研究結(jié)果發(fā)表在最新一期《美國醫(yī)學(xué)會》雜志上。 這對癌癥患者而言可謂喜憂參半。一項由3萬5千多名絕經(jīng)后婦女參與的研究發(fā)現(xiàn)，服用魚油的婦女比不服用魚油的婦女患乳腺癌的幾率似乎少了一半。這項研究發(fā)表在６月份的《癌癥流行病學(xué)、生物標記物與預(yù)防》上。 但是，10月15號出版《癌癥研究》發(fā)現(xiàn)，腸道發(fā)炎的小鼠在攝入高劑量的魚油后會患上結(jié)腸炎和轉(zhuǎn)移能力極強的結(jié)腸癌。 如此說來，魚油實際上可能只在某些情況下起到助益健康的作用。當(dāng)然，你也大可不必把這些研究結(jié)果看得過重。
