In vitro approach of dietary and host related factors affecting digestion of animal-origin foods under cystic fibrosis disease

Among the available methodologies to study food digestion, in vitro digestion models have raised as a valid procedure. In vitro digestion consists of simulating the digestion process in the laboratory, by reproducing the physiological conditions in terms of digestive fluids composition (electrolytes and enzymes), pH, temperature, mechanical forces and duration of the oral, gastric and intestinal stages.
