Background: Discretionary foods (DF) should be consumed occasionally but contribute 35% of total energy intake (%en), highlighting the need to profile consumption.

Methods: Data from the 2011-12 National Nutrition and Physical Activity Survey were used, including self-reported eating occasions (REO). Prevalence of consumption, DF serves (1 = 600kJ), nutrient contribution from DF and top DF food groups by REO were calculated by age, gender, socio-economic status (SES) and weight status. DF consumers (>0 grams) were classified according to quartiles of DF intake.

Results: The majority of adults consumed DF (97%) and median serves consumed was 3.9/day. Half (50%) of all REO contained a DF.  The REO with the most DF consumers were ‘lunch’ and ‘dinner’; which together contributed 45% of total DF energy intake.Cakes, muffins, scones, cake-type desserts (‘cakes’) contributed the most DF energy (8.4%). Top contributor to DF energy for males was beer (10.9%) and for females was ‘cakes’ (10.1%). Pastries provided the highest DF energy contribution among lowest SES; and wine among highest SES. DF contributed 49.4% of total sugar and 42.2% of total saturated fat.  The top quartile of %en from DF consumed an average of 10±4.5 DF serves, had a higher prevalence of males, younger adults, low SES and higher mean waist circumference but not higher BMI.

Conclusion: A focus on decreasing consumption of the largest contributors to DF may be useful to decrease saturated fat and sugar intakes, especially during lunch and dinner and amongst the highest consumers.
