Nutrient patterns and their food sources in an International Study Setting: report from the EPIC study.

ABSTRACT:

Background

Compared to food patterns, nutrient patterns have been rarely used particularly at international level. We studied, in the context of a multi-center study with heterogeneous data, the methodological challenges regarding pattern analyses.
