PubMed 41080174 ↗Conclusion: Our analysis suggests that FF consumption beneficially impacts the frequency of bowel movements, stool consistency, incidence of hard stools, intestinal transit time, abdominal symptoms, bloating, borborygmi, flatulence and degree of constipation.
PubMed 41141260 ↗Conclusion: We present further evidence supporting a role for gut microbiota in mediating the reduced nutrient absorption and that hydrolysis of bovine WP mitigates, at least some of, this effect and increases growth compared with formulas with intact proteins. We envisage that these findings, based on proteins sourced from cow's milk, will inform improvements in infant formula that increases nutrient absorption and support healthier growth using a protein content much lower than the current regulatory threshold of 1.8 g/100 kcal.
