【轉貼】從小我們被教導動物性油脂富含飽和脂肪酸，會阻塞血管，提高心血管疾病風險。也因此我們才有這麼多低脂的"健康食品"，低脂牛奶，市面上的料理用油也大多以植物性為主。
不過，近年來許多新的證據顯示，飽和脂肪與心血管疾病的關聯性非常薄弱，甚至可能不存在。
UpToDate，一個被全世界醫師、專家所信賴的臨床指引系統，最近也修改了對於飽和脂肪酸的指引。（史考特幾乎每天都會用UpToDate來查資料，這個資料庫真的很厲害XD）
以下引自原文：
"Although it is known that there is a continuous graded relationship between serum cholesterol concentration and coronary heart disease (CHD), and that dietary intake of saturated fats raises total serum cholesterol, a 2014 meta-analysis of prospective observational studies found no association between intake of saturated fat and risk for CHD.
The meta-analysis also found no relationship between monounsaturated fat intake and CHD, but suggested a reduction in CHD with higher intake of omega-3 polyunsaturated fats; a benefit with omega-6 polyunsaturated fats remains uncertain.
Given these results, we no longer suggest avoiding saturated fats per se, although many foods high in saturated fats are less healthy than foods containing lower levels.
In particular, we no longer feel there is substantial evidence for choosing dairy products based on low-fat content (such as choosing skim milk in preference to higher fat milk). We continue to advise reducing intake of trans fatty acids."

「儘管我們知道飽和脂肪會升高血液中的膽固醇，而血液中膽固醇濃度又與心血管疾病的風險呈正相關。2014年的一篇整合性研究告訴我們：飽和脂肪與心血管疾病的相關性其實不存在。」
「這個整合性研究告訴我們單元不飽和脂肪酸與心血管疾病之間沒有相關性，不過omega-3的多元不飽和脂肪酸似乎能降低心血管風險，而omega-6的角色尚不明朗」
「根據這個研究結果，我們不再建議民眾降低飽和脂肪酸的攝取。儘管許多富含飽和脂肪的食物與食品常常比較不健康。」
「值得一提的是，我們不再認為有足夠的證據來建議民眾選擇低脂的乳品（例如低脂與全脂牛乳）。不過我們仍然建議降低反式脂肪的攝取。」
