Novel approaches are being used to more accurately capture dietary intake, diet composites, and measurement of biomarkers and nutrient status that are indicators of nutritional exposure.

These solutions include the development of standardized nutrient databases, a biomarker validation program, and dietary calibration that included the development of a standardized computer program for 24-hour dietary recall interviews.

Lessons learned from Phase 1 have presented opportunities to refine the processes for Phase 2 and subsequent research by the IBCN. Phase 1 of the study highlighted the need for adequate protocol training, because simply providing a protocol to investigators was insufficient because of differences in cultures and disciplines among countries. Improvements must be made in the documents and instructions to reduce variation in the types of information (eg, weights and menus) received with the diet shipments. Finally, the requirements for ethics approval varied greatly among countries, with some requiring a proposal for the entire project and a literature review, which resulted in a process that was slow and complicated.\u003C\/p\u003E\n         \u003Cp id=\u0022p-11\u0022\u003EExtensive progress has been made in establishing the IBCN project, stated Prof. Welch, providing a foundation to move on to the next research stages and expand the number of participating countries and researchers.\u003C\/p\u003E\n      \u003C\/div\u003E\u003Cul class=\u0022copyright-statement\u0022\u003E\u003Cli class=\u0022fn\u0022 id=\u0022copyright-statement-1\u0022\u003E\u00a9 2014 MD Conference Express\u00ae\u003C\/li\u003E\u003C\/ul\u003E\u003Cspan class=\u0022highwire-journal-article-marker-end\u0022\u003E\u003C\/span\u003E\u003C\/div\u003E\u003Cspan id=\u0022related-urls\u0022\u003E\u003C\/span\u003E\u003C\/div\u003E\u003Ca href=\u0022http:\/\/mdc.sagepub.com\/content\/14\/5\/21.abstract\u0022 class=\u0022hw-link hw-link-article-abstract\u0022 data-icon-position=\u0022\u0022 data-hide-link-title=\u00220\u0022\u003EView Summary\u003C\/a\u003E\u003C\/div\u003E  \u003C\/div\u003E\n\n  \n  \u003C\/div\u003E\n\u003C\/div\u003E\n  \u003C\/div\u003E\n\u003C\/div\u003E\n\u003C\/div\u003E\u003Cscript type=\u0022text\/javascript\u0022 src=\u0022http:\/\/mdc.sagepub.com\/sites\/all\/modules\/highwire\/highwire\/plugins\/highwire_markup_process\/js\/highwire_figures.js?nzlxi2\u0022\u003E\u003C\/script\u003E\n\u003Cscript type=\u0022text\/javascript\u0022 src=\u0022http:\/\/mdc.sagepub.com\/sites\/all\/modules\/highwire\/highwire\/plugins\/highwire_markup_process\/js\/highwire_openurl.js?nzlxi2\u0022\u003E\u003C\/script\u003E\n\u003C\/body\u003E\u003C\/html\u003E"}
