Gastrointestinal (GI) health is central to our overall health and well-being, with a role that extends beyond digestion and absorption of nutrients and fluid. A healthy GI development and function also impacts immune function and even our mood and mental wellbeing. At Danone Research & Innovation we understand that optimal nutrition during the first 1000 days is of major relevance for the development of a healthy, well-functioning GI tract and lays the foundation for future health.
