Self-reported diet is prone to measurement error. Analytical models of diet may include several foods or nutrients to avoid confounding. Such multivariate models of diet may be affected by errors correlated among the dietary covariates, which may introduce bias of unpredictable direction and magnitude. The authors used 1993-1998 data from the European Prospective Investigation into Cancer and N...

OBJECTIVE To examine how different definitions of meals and snacks can affect the associations of meal frequency (MF) and snack frequency (SF) with dietary intake and adiposity measures. DESIGN Based on 7 d weighed dietary record data, all eating occasions providing ≥210 kJ of energy were divided into meals or snacks based on contribution to energy intake (≥15 % or <15 %) or time (06.00-10.00...

BACKGROUND If several risk factors for disease are considered in a regression model and these factors are affected by measurement errors, the observed relative risk will be attenuated. In nutritional epidemiology, several nutrient variables show strong correlation, described as collinearity. The observed relative risk will then depend not only on the validity of the chosen diet assessment metho...

BACKGROUND Since information about macro- and micronutrient intake among vegans is limited we aimed to determine and evaluate their dietary and supplementary intake. METHODS Seventy 18-61 years old Danish vegans completed a four-day weighed food record from which their daily intake of macro- and micronutrients was assessed and subsequently compared to an age-range-matched group of 1,257 omniv...

The diet-plasma relationships for carotenoids were examined in a group of 98 nonsmoking premenopausal women who participated in the cross-sectional phase of the National Cancer Institute (NCI)-US Department of Agriculture (USDA) diet study on alcohol-hormone metabolism, 1988-90. With use of the newly developed USDA-NCI carotenoid foodcomposition database, the mean daily intakes of carotenoids w...

The excavation of the north house at archaeological site Arucci (Aroche, Huelva) has provided interesting data for understanding city planning in general, and domestic architecture particular. Investigation their environments allowed identification distinct functions which they were intended, including two significant tabernae that connected to one main thoroughfares city. In them, an set ceram...

The aim of the present study was to assess the respective contributions of regional and socio-economic factors to dietary pattern. We used the data from the final MONICA (MONItoring of trends and determinants in Cardiovascular disease) population survey conducted in the three French centres in 1995-7 among a representative sample of 976 men aged 45-64 years. Dietary intake was assessed using a ...

BACKGROUND Researchers suspect that the accepted adequate ascorbic acid plasma concentration is not being met even after dietary intake of the recommended amount of vitamin C. Current dietary intake recommendation in Poland is 60 mg per day for women and 75 mg per day for man (EAR), while in Western Europe and North America is higher and amounts to 75-90 mg per day. OBJECTIVE The paper aimed ...

The vast African continent is an ecological stage with ever-changing scenery and casts of characters that included human ancestors. The mammals that came and went upon this stage have been enlisted to help answer a compelling question relevant to our own evolutionary story: How do land animals respond to long-term environmental change? The paper by Cerling et al. (1) is a milestone in this ques...
