The impact of the source of dietary fat and the level of dietary fiber on digestibility and energy metabolism were studied in human (six male, six female) volunteers. Subjects were divided into two diet treatment groups, high fiber [29.0 g total dietary fiber (TDF)/d] and low fiber (18.6 g TDF/d), for the duration of the study. Each participated in three,(More)
Excretion of malondialdehyde (MDA)-generating substances in the urine has been suggested as an indicator ofin vivo lipid peroxidation. However, MDA in the urine also reflects the amount of lipid peroxidation products consumed in the diet. We determined MDA as the thiobarbituric acid (TBA)-MDA complex in urine of 19 healthy adults (10 male and 9 female) fed(More)

OBJECTIVE We estimated the usual nutrient intake of US children aged 6-23 mo examined in NHANES 2009-2012 and compared them to(More)
