背景：评估医生对饮食对血脂和脂蛋白基本影响的营养知识。方法：对美国随机抽取的 6000 名拥有内科或心脏病学执照的医生进行匿名邮寄饮食知识调查。结果：答复率：16% (n = 639)。一半的医生不知道菜籽油，26% 的医生不知道橄榄油是单不饱和脂肪的良好来源。 93%（心脏病专家 84% vs 内科医生 96%；p < 0.001）不知道低脂饮食通常会增加血液甘油三酯。大约四分之三（70% 的心脏病专家 vs. 77% 内科医生；p < 0.01）不知道低脂饮食会降低 HDL-c，而近一半 (45%) 认为低脂饮食不会改变 HDL-c。 结论：如果医生要实施饮食和胆固醇管理指南，他们可能需要更加了解营养知识。
Background: To assess the nutrition knowledge of physicians on the basic effects of diet on blood lipids and lipoproteins.Methods: Anonymous mailed dietary knowledge surveys to 6000 randomly selected physicians in the United States licensed in either Internal Medicine or Cardiology.Results: Response rate: 16% (n = 639). Half of the physicians did not know that canola oil and 26% did not know olive oil were good sources of monounsaturated fat. Ninety-three percent (84% of cardiologists vs. 96% of internists; p < 0.001) did not know that a low-fat diet, in general, would increase blood triglycerides. Approximately three-quarters (70% of cardiologists vs. 77% of internists; p < 0.01) did not know a low-fat diet would decrease HDL-c and almost half (45%) thought that a low-fat diet would not change HDL-c.Conclusions: If physicians are to implement dietary and cholesterol management guidelines, they will likely need to become more knowledgeable about nutrition.
