Researchers from the University of Seoul in South Korea have discovered that consuming 85% dark chocolate regularly may positively influence mood. They suggest an optimal intake of 30 grams daily. However, with only 46 participants, larger studies are needed to validate these findings.
Chocolate is a beloved treat for many. Past inquiries, like our 2017 exploration, have examined potential dependency due to its mild stimulant effects on the brain's reward pathways.
Building on this, a study forthcoming in the Journal of Nutritional Biochemistry (January 2022) from Seoul University researchers investigated dark chocolate's impact on well-being. Their findings indicate that 30 grams of 85% dark chocolate daily supports better mood.
This research is the first to demonstrate how daily dark chocolate consumption affects physiological and psychological states. Analysis of participants' stool samples revealed greater intestinal microbiota diversity among those eating 85% dark chocolate.
The study noted elevated levels of Blautia obeum and reduced levels of Faecalibacterium prausnitzii in 85% dark chocolate consumers, pointing to its genuine prebiotic properties. This shift in gut bacteria diversity and abundance appears to enhance emotional well-being. Notably, these effects were absent in chocolates with less than 85% cocoa, including milk, white chocolate, or related confections.
While promising, the study's small cohort of 46 participants limits its conclusions. Additional research is essential to confirm these mood-boosting benefits.
