I am a medical student, so let me educate you on this topic. There is a type of food called oligosaccharides. They cannot be digested by the human body, but they are very popular foods for the beneficial bacteria in the intestines. If the food you eat contains these oligosaccharides, it can increase the number of beneficial bacteria in the intestines and reduce the harmful bacteria in the intestines, which is better for the intestines. The patented prebiotic combination contained in the fully imported Chinese label version of Aptamil is a combination of galacto-oligosaccharides and polyfructose. It has a patented ratio and is designed to make the baby's intestines healthier.
