A key place for probiotics in mental health
Commenting on the study, Uma Naidoo, MD, said: “As I shared throughout my first book, This is Your Brain on Food, there is a real place for the use of probiotics in mental health, including the importance of the gut-brain connection.”
Dr. Naidoo is the director of nutritional and metabolic psychiatry at Massachusetts General Hospital and of nutritional psychiatry at the MGH Academy, both in Boston.
She noted that, when a person stops using a probiotic after trying it out, the positive changes in the gut are reversed, so “remaining consistent in taking the probiotic is important if you have found it helpful for your mood.”
Dr. Naidoo added that “each person’s gut microbiome is so unique that it is likely not every human being will have the same reaction to a probiotic.”
“Eating foods with live probiotics may also benefit gut health and, therefore, mood,” she said. The same goes with eating fermented foods with live active cultures.”
The study was funded by a Medical Research Council Industrial CASE PhD Studentship with ADM Protexin (supplier of the probiotics) as the industry partner and additional support from Freya Green. Dr. Nikolova has received grants from the Medical Research Council and ADM Protexin during the conduct of the study as well as personal fees from Janssen outside the submitted work.
