In self-selection feeding paradigms, rats display differential patterns of nutrient (protein, carbohydrate or fat) intake. Factors known to influence this selection include brain peptides as well as circadian parameters. In this series of experiments we investigated the role of PVN galanin in nutrient intake during the early and late dark periods in the rat. Rats were allowed to select between ...

The effect of inclusion level on nutrient intake, digestibility, nitrogen metabolism and haematological parameters of West African Dwarf (WAD) goat fed Cajanus cajan as supplement to cassava peels was investigated in a completely randomized design experiment using twenty-four WAD goats with average initial weight of 10.75±0.85kg (March-September, 2016). There were four treatments as: A...

BACKGROUND/OBJECTIVES Assessing changes in energy intake and dietary sources is important to understand trends in the prevalence of obesity. Thus, we examined trends in energy intake and its nutrient and food sources in Korean adults from 1998 through 2015. SUBJECTS/METHODS This study included 70,769 subjects aged ≥ 19 years who completed a nutrition survey. Subject data were obtained from th...

We discuss the problem of assessing nutrient intake relative to the tolerable upper intake levels (UL) for the nutrient proposed by the Institute of Medicine and focus on 2 important topics: the estimation of usual nutrient intake distributions and the extent to which intakes above the UL can be considered risky. With the information that is currently available for most nutrients, it is not pos...

The energy and nutrient content of a food item provides information on its nutritional characteristics, and this information has through the years been captured in food composition databases around the world. Information on the energy and nutrient composition of foods is a prerequisite for analysing dietary intake data and aids in establishing the diet/disease relationship in a community or cou...

BACKGROUND Advances in nutritional assessment are continuing to embrace developments in computer technology. The online Food4Me food frequency questionnaire (FFQ) was created as an electronic system for the collection of nutrient intake data. To ensure its accuracy in assessing both nutrient and food group intake, further validation against data obtained using a reliable, but independent, instr...

OBJECTIVE Because the percentage of missing portion sizes was large in the Aerobics Center Longitudinal Study (ACLS), careful consideration of the accuracy of standard portion sizes was necessary. The purpose of the present study was to investigate the consequences of using standard portion sizes instead of reported portion sizes on subjects' nutrient intake. METHODS In 2307 men and 411 women...
