Difference: self-reported - measured (a negative value means infra-reported; a positive value means over-reported).

The values do not sum 911 because there are 10 participants with other race. Due to limited number of participants we do not represent category.

The values do not sum 911 because there are 191 missing values for this variable. Soy consumer: ≥1 g of soy protein per day.

Semi-vegetarian: low meat consumption and pesco; Vegetarian: Vegan and Lactovegetarian.

Values are expressed as means and (95% Confidence Interval).

p values of differences between groups were obtained through T Student test or ANOVA.
