* Wilcoxon Signed Rank Sum; ** Paired t-test; 1 Reported by participants prior to trial commencement; 2 The washout period acted as a condition in itself as it was free from all milk and soy protein; 3 The number of participants in each condition is not the same because some participants ceased participation in the study after the various conditions; 4 Resolution of constipation = >8 bowel motions per fortnight; 5 The difference between the two milk epochs cow’s milk β casein A1 and for cow’s milk casein A2; 6 The difference between the 3 epochs.
