  1. CHO carbohydrate, MFP meat, fish and poultry. All data are mean (± SD).
  2. P* values derived from ANCOVA after adjustment for confounders (e.g. age, gender, BMI, physical activity and dietary energy intake). The significant difference between all of tertiles according to Tukey’s post-hoc comparisons. The bolded values show the statistically significance.
