Dietary assessment Each participant filled in a prospective questionnaire, where dietary data from 3 days were collected (2 working days, 1 weekend day). For dietary intake calculations Nutridan program was used. As nutritional data of some special vegan products are not available in the database, vegans were asked to collect packages from these products with producer declared nutritional content, and these data were used for calculations. Saccharides, lipid and protein intake were calculated separately. BCAA content of dietary proteins was estimated using nutritional database.
