DGI, Dietary Guideline Index; sd, standard deviation.
Fruit intake of ≥2 serves and vegetable intake of ≥5 serves were considered as satisfactory. Cereal food intakes of ≥4⋅5 serves for men and ≥3 serves for women were considered as satisfactory. Total protein intakes of ≥2⋅5 serves for men and ≥2 serves for women were satisfactory. Dairy intakes of ≥3⋅5 serves for men and ≥4 serves for women were satisfactory. Whole-grain consumption equal to or more than half of total cereal intake serves and low-fat dairy equal to or more than half of total dairy intake serves were considered as meeting requirements here. Unsaturated fats/oils ratio of ≥0⋅5 considered as meeting requirements. Discretionary foods of ≤3 serves for men and ≤2⋅5 serves for women were considered as satisfactory.
