Perceptions of Probiotics and Kombucha Consumption in Relation to Emotion Regulation: An Exploratory Study Comparing Portugal and Brazil

Abstract

Probiotic products have been the focus of research for several years due to the potential of their biological properties to impact mental health, mood, and cognitive functions. Kombucha is a probiotic drink that has been reported to be beneficial for mental health, particularly at the level of emotion regulation. This study aims to understand the perception of the Portuguese and Brazilian populations regarding the consumption of probiotics and Kombucha, as well as to understand these consumers’ perceptions related to the impact on emotion regulation (and the impact of this consumption on emotion regulation). The research was conducted through an online questionnaire and had a total sample of 256 participants. The results show that there are no statistically significant differences between the consumption of probiotics and Kombucha when comparing the Portuguese and Brazilian samples. Additionally, this study reveals a significant association between probiotic consumption patterns in both the Portuguese and Brazilian samples. However, no statistically significant relationship was found between the consumption of probiotics and Kombucha and emotion regulation. This study intends to contribute to the increase in knowledge about the perception of probiotics and Kombucha consumption in relation to emotion regulation, and to draw attention to the importance of this topic in the community (society, academia, and industry).
