Most of the common cancers in Canada have been associated in some way with diet. More than half of all newly diagnosed cancers and cancer-related deaths are limited to three sites in each sex: lung, prostate, and colorectum in men and breast, colorectum, and lung in women. The earliest and strongest epidemiologic evidence associating diet and cancer has come from descriptive correlation studies. The findings of subsequent, more powerful, analytic studies have been inconsistent. The author reviews the importance of diet for common cancers in Canada and considers the methodologic limitations of various study designs.
在加拿大，大多数常见癌症都在某种程度上与饮食有关。所有新诊断出的癌症以及与癌症相关的死亡中，超过一半局限于男女各自的三个部位：男性为肺癌、前列腺癌和结直肠癌，女性为乳腺癌、结直肠癌和肺癌。将饮食与癌症联系起来的最早且最有力的流行病学证据来自描述性关联研究。后续更具说服力的分析性研究结果并不一致。作者回顾了饮食对加拿大常见癌症的重要性，并考虑了各种研究设计在方法学上的局限性。
