a: Unadjusted Pearson correlation coefficient

b: Nutrient intakes were adjusted for age, sex and energy

‡: The data (Alpha tocopherol, Vitamin K, Vitamin B1, Vitamin B2, Niacin, Vitamin B6, and Vitamin B12) were transformed by natural log to improve normality

CFFQ: Food frequency questionnaire for dietary assessment in children

AFFQ: Food frequency questionnaire for dietary assessment in adults

WDR: Weighed dietary record

SD: Standard deviation
