Inconsistent dietary assessment tools may bias results in assessing the relations between specific foods and coronary heart disease risk in the EPICOR Study.

摘要

In a recent article by Bendinelli et al (1), data from 5 European Prospective Investigation into Cancer and Nutrition (EPIC) study centers in Italy were used to assess the influence of fruit, vegetable, and olive oil consumption on coronary heart disease (CHD) risk. The authors found that risk of CHD was reduced when comparing individuals in the highest quartiles of leafy vegetable and olive oil consumption with those in the lowest quartiles, whereas no association was found with fruit intake. Although the data provide a compelling argument for the importance of consuming healthful foods in the context of preventing heart disease, the use of a uniform dietary assessment tool across each of the 5 centers could have strengthened the study.
