¹Estimated average requirement for energy intake, weighted for the study population. Estimated average requirements for energy intake for men and women aged 19-50 years are 10.6 MJ/day and 8.10 MJ/day respectively.
² Reference Nutrient Intake for protein, weighted for the study population. Reference nutrient intakes for protein for men and women aged 19-50 years are 55.5 mg/day and 45 mg/day respectively.
³Population average
⁴ Reference Nutrient Intake
⁵ Reference Nutrient Intake for riboflavin, weighted for the study population. Reference nutrient intakes for riboflavin for men and women aged 19-50 years are 1.3 mg/day and 1.1 mg/day respectively.
^‡Significance was assessed using two-tailed one-sample t-tests.
