BOTANICAL SUPPLEMENTS FOR GUT HEALTH P. Morazzoni Indena S.p.A. Milan, Italy GUT HEALTH A term widely "abused" in the medical literature and by the food industry. It includes gut health and gastrointestinal health. Other abdominal organs, such as liver, pancreas, spleen or kidney are usually not associated with gut health.
