The impact of having caeserian delivery on an infant's initial gut biome is relatively new knowledge, which is leading to changes in healthcare delivery for child health.
Maintaining good gut biome health is also still being researched, as well as what actually is a good gut biome. Whether it is dependent on different locations, or diets and what are the side effects.
This is not just "good food is good for you" research that the Gates Foundation is funding.
It's fundamental basic research that pharma development is not focused on delivering that will lead to better health worldwide.
