Recent nutrition recommendations are directed towards prevention of chronic degenerative diseases, particularly coronary heart disease and cancer. This focus is in response to morbidity and mortality trends during this century. The evidence supporting such dietary changes remains inconclusive because of difficulties inherent in the measurement of usual dietary intake. The association between dietary fat and breast cancer is reviewed as an example of the problems faced in assessing whether a dietary component does alter the risk of disease. Current recommendations suggest a population-based approach to dietary modifications; the public health implications of this approach are discussed.
近期的营养建议旨在预防慢性退行性疾病，尤其是冠心病和癌症。这一重点是对本世纪发病率和死亡率趋势的回应。由于日常饮食摄入量测量存在固有困难，支持此类饮食改变的证据仍然不确凿。作为评估饮食成分是否确实会改变疾病风险时所面临问题的一个例子，本文对膳食脂肪与乳腺癌之间的关联进行了综述。当前的建议提出了一种基于人群的饮食调整方法；并讨论了这种方法对公共卫生的影响。
