Our Eating and Sexual Behavior Is Influenced by the Gut Microbiome

First, the birth-giving mother’s microbiome colonizes the lining of a newborn baby’s gut; however the breast milk microbiome seems to play even more of an influential role for the lifetime development of the gastrointestinal ecosystem (Daft et al. 2015). After this early period of life, diet has the capability to change the microbiome rapidly and reproducibly, but also unsustainably; once a special diet is over, the microbial diversity can return to the pre-diet level within few days (David et al. 2014). The brain-gut axis (hypothalamic-pituitary-adrenal [HPA] axis) is a bidirectional communication system between the central nervous system and the gastrointestinal tract. Via this axis, bacteria send molecular information to influence what “we” want to eat, and it is sometimes difficult for us to change this behavior as studies with obese patients showed (Alcock et al. 2014).

The decision regarding which partner we select is very important for healthy children with a strong immune system, which is one of our most complex organs, and heavily educated by the composition of our microbiome. Moreover, the neuroendocrine system determines our personal smell partially via bacterial volatiles. People with different smells are much more interested in each other than those with similar smell, which helps to maintain and develop the strong immune system for further generations with the highest possible diversity rates and combinatorial variations. In general, the microbiome has a crucial role in social development (Desbonet et al. 2014).
