What’s the latest in prebiotic research? May Edition
This monthly feature provides an overview of some of the latest studies on prebiotics. We’ll share key findings and insights from the studies. Have a study you’d like us to cover? Email GPA Communications Director Traci Kantowski firstname.lastname@example.org.
Dietary interventions for autism spectrum disorder: An updated systematic review of human studies
This systematic review provides an updated analysis of the efficacy of antioxidants, probiotics, prebiotics, camel milk and vitamin D in human studies that investigated therapeutic benefits of these dietary interventions in autism.
Key takeaways: In the studies included in this review, prebiotics decreased levels of inflammatory cytokines, improved behavioral and GI symptoms and improved gut microbiota in subjects with autism spectrum disorder. Only three studies were included that looked at prebiotics, more research is needed.

Impact of probiotics and prebiotics in the modulation of the major events of the aging process: A systematic review of randomized controlled trials
This systematic review evaluated the impact of probiotics, prebiotics, and synbiotics on the major events that affect individuals aged 65 or older.
Key takeaways: Nine randomized controlled trials were included in this review. Most of the studies demonstrated an improvement in issues related to aging (glucose homeostasis, cognitive function, frailty phenotype, gut microbiota profile, immune parameters). The authors suggest that “modifications of older persons’ gut microbiota by means of probiotics and prebiotics consumption may be a valid strategy to improve health and attenuate some physiological deterioration that occurs during the aging process”.

The Potential of Prebiotic and Probiotic Supplementation During Obese Pregnancy to Improve Maternal and Offspring’s Metabolic Health and Reduce Obesity Risk-A Narrative Review
This intriguing narrative review discusses the potential of pre- and probiotic interventions in modulating maternal obesity associated dysbiosis to limit the child’s obesity risk.
Few studies exist in humans especially related to prebiotics. However, 4 animal studies revealed prebiotic supplementation decreased the offspring’s obesity risk, while probiotic supplementation in humans failed to show positive impacts in the offspring. While this evidence is interesting and promising, how the animal data transfers to humans is not clear, trials in humans are needed.
