The effects of day-of-the-week on reported dietary intake were examined in 10-year-old children.
Two hundred-eighty-one children (42% black ; 50% female) completed a 24-hour dietary recall interview, with 78% representing weekday and 22% representing Sunday eating patterns.
No Sunday versus weekday differences were noted for energy, protein, fat, carbohydrate or sodium.
Mixed protein (mixture of animal and vegetable protein) intakes were higher during the week (p<0.0001), particularly at breakfast.
Lactose and fructose intakes were higher on the weekday (p<0.0001) and PUFA, MUFA and cholesterol intakes were higher on Sunday.
The daily differences noted were contributed largely by differences in the breakfast and lunch meals, particularly those consumed at school.
The dinner meal contributed greater lactose on Sunday (p<0.01) and greater starch on weekdays (p<0.05).
Nutrient intakes from snacks did not differ between weekdays versus Sunday.
Sunday intakes had significantly greater inter-subject variability than weekday intakes for energy, protein, SFA, cholesterol, carbohydrate, starch and sodium.
Variations in nutrient intakes on Sunday versus weekdays was largely explained by differences in food group consumption.
Significant differences were noted in percent of energy from fruits, milk and meats (higher on weekdays) and vegetables, poultry, eggs and pork (higher on Sunday). (...)
