gastrointestinal tract. Because the pH of the fermented whey is lower than the
pH generally observed in the small intestine (Heres et al, 2003), the fermented
whey lowers the small intestine pH. It was shown that a normal decrease in
small intestine pH can improve nutrient digestibility as was shown in current
study.
