A critical evaluation of the duplicate-portion technique in dietary surveys

Article Abstract:

The duplicate-portion technique of measuring nutrient intake influences free-living subjects sufficiently that the substitute portions cannot be taken to represent the habitual intake of these subjects. The method may still be useful for institutional studies and metabolic balance studies, where the subject does not control the portions selected. The studies reviewed indicate that duplicate-portion analyses of free-living subjects tended to underestimate total nutrient intake significantly, and suggest that subjects may select more healthy portions when assembling duplicate portions.

High fruit intake may reduce mortality among middle-aged and elderly men. The Study of Men Born in 1913

Article Abstract:

High fruit consumption could have a positive impact on mortality in a general population sample, according to research among 792 men who were screened in 1967 as part of the Study of Men Born in 1913, a longitudinal prospective cohort study of men living in the Goteborg, Sweden. This positive impact could still be identified after taking account of the traditional cardiovascular risk factors. High fruit consumption could be an indicator of a healthier lifestyle, but in this study low fruit consumption was an independent risk factor for death.

Energy intake and expenditure: validation of a diet history by heart rate monitoring, activity diary and doubly labeled water

Article Abstract:

A new study investigates energy intake and expenditure by validating a diet history through an activity diary, heart rate monitoring and doubly labeled water. The study of healthy 73-year-old men and women shows that the dietary history method for measuring energy intake was in accordance with the activity diary but was lower than both heart rate monitoring and doubly labeled water.
