Values are expressed as mean ± SD. As the influence of order was not significant by the linear general model for any variable, values of the two periods of the same water consumption were pooled. Time effect and time × water interaction by repeated measures ANOVA. * Values expressed as median (IQR). Difference between baseline and eight weeks by Wilcoxon signed-rank test; † Including 1 L of the test mineral waters.
