The Claim
A common misconception is that prebiotics solely benefit gut health and do not influence other aspects of health such as immune function or mental health.
Origin
This belief stems from the primary association of prebiotics with gut health in media and product labels.
What Science Says
Emerging research shows that prebiotics can have systemic effects beyond the gut. For instance, meta-analyses indicate they may modulate immune function and have potential impacts on mental health by influencing the gut-brain axis (Sarkar et al., 2018).
Verdict
Partially True
