Dietary control
The volunteers were instructed to follow their usual diet and physical activity between visits. To monitor possible changes during the assay, at baseline and at 5, 10 and 15 weeks of the trial, all participants completed a 72 h detailed dietary intake report specifying the type and/or brand of the product and the portion or weight of food consumed. Dietary intake was analysed using the DIAL software (Alce Ingeniería, Madrid, Spain). This software allows the addition of new food products and their nutrient composition. Therefore, labelling information was used to complete the data for many foods, most of them formulated for vegans.
