We pooled data from 5 large validation studies (1999–2009) of dietary self-report
instruments that used recovery biomarkers as referents, to assess food frequency …

New technologies are promising for the use of short-term instruments for dietary data
collection; however, innovative tools should be validated against objective biomarkers. The …

Technology-based dietary assessment offers solutions to many of the limitations of
traditional dietary assessment methodologies including cost, participation rates and the …

Background The possibility that lifestyle factors such as diet, specifically potassium intake,
may modify the risk of stroke has been suggested by several observational cohort studies …

Dietary assessment traditionally relies on self-reported data, which are often inaccurate and
may result in erroneous diet–disease risk associations. We illustrate how urinary metabolic …

Background: Limited knowledge regarding the reproducibility of biomarkers in 24-h urine
samples has hindered the collection and use of the samples in epidemiologic studies …

Following a request from the European Commission, the EFSA Panel on Dietetic Products,
