The quality of our dietary choices is an important factor affecting both our psychological and physical health (Almudena Sánchez-Villegas et al, 2013). Nowadays, there are many widespread dietary approaches, without users knowing all the small but important details that affect our body’s biochemistry and our psychology. One of these small details is the production of the neurotransmitter serotonin (Trisha A. Jenkins et al, 2016).

Serotonin is a neurotransmitter that helps regulate sleep and appetite, mediates mood and inhibits pain. Serotonin production is done in the intestines and the brain. Since the highest rate of serotonin production is in the gastrointestinal tract and the gastrointestinal tract is lined with hundreds of millions of nerve cells (Paul R. Albert et al., 2013), good internal functioning of your digestive system becomes more important both in the absorption of nutrients as well as the health of nerve pathways that travel directly between the intestine and the brain (Ye Li et al, 2017).

The effect of intestinal microbility on behavioral development and neurochemical changes in the brain is an evolving subject to research on the treatment of disorders such as anxiety and depression due to emerging anxiety about intestinal brain interaction and its ability to affect the development of psychological disorders Slyepchenko A et al., 2014). Studies have shown that people who consume probiotic-rich foods (Lye Huey Shi et al., 2016) or supplements in probiotics, their anxiety levels, anxiety perception, and the right way of thinking are improving, compared to people who have not a healthy intestinal flora.
