Portion sizes are given based on French standard recommendation; Estimates and 95 % CI of the value factor effects on the IGQ global score were obtained by calculating the LS-Means differences between the value of interest LS-Mean and the reference value LS-Mean within the factor (ref.) for qualitative factors and as a difference of intake equals to the portion size for quantitative factors (e.g. for any other constant factor elsewhere in the model, +65-year-old participants have a significant reduction of −4·9 points (95 % CI –8·45, −1·31) of IGQ global score as compared with 18–24-year-old participants (ref.)).
