Relevance of gut microbiome research in food safety assessment
AI summary Read the abstract
This review examines evidence that food additives and microplastics may disrupt the gut microbiome and, in turn, affect human health. The researchers discuss how these non-nutritive dietary compounds can alter gut bacterial communities through mechanisms that are often overlooked in food safety evaluations. They recommend integrating gut microbiome science into food risk assessment frameworks to better protect human health.
The gut microbiome is indispensable for the host physiological functioning. Yet, the impact of non-nutritious dietary compounds on the human gut microbiota and the role of the gut microbes in their metabolism and potential adverse biological effects have been overlooked. Identifying potential hazards and benefits would contribute to protecting and harnessing the gut microbiome's role in supporting human health. We discuss the evidence on the potential detrimental impact of certain food additives and microplastics on the gut microbiome and human health, with a focus on underlying mechanisms and causality. We provide recommendations for the incorporation of gut microbiome science in food risk assessment and identify the knowledge and tools needed to fill these gaps. The incorporation of gut microbiome endpoints to safety assessments, together with well-established toxicity and mutagenicity studies, might better inform the risk assessment of certain contaminants in food, and/or food additives.

Relevance of gut microbiome research in food safety assessment
AI summary Read the abstract
This review examined how the gut microbiome metabolizes non-nutritious dietary compounds, arguing that gut microbial processing of food contaminants and additives is an underappreciated dimension of food safety assessment.
The potential influence of food additives and contaminants on the gut microbiota: A comprehensive review
AI summary Read the abstract
This comprehensive review examines how food additives and contaminants, including pesticides, heavy metals, microplastics, and antibiotics, affect the gut microbiota. Researchers found that these substances can disrupt the balance of gut microbes, leading to inflammation, gastrointestinal injury, and altered production of beneficial short-chain fatty acids. The study emphasizes the need for further research into the mechanisms by which dietary contaminants affect gut health and overall wellbeing.
Microbial risks associated with microplastics in the food chain and possible control measures (literature review). Part 1. Dietary intake and influence on the gut microbiota
AI summary Read the abstract
This review summarizes evidence that microplastics commonly found in food and drinking water can disrupt the human gut microbiome when ingested. Studies show that microplastics alter the composition and function of intestinal bacteria, potentially affecting digestion, immunity, and overall health. Since a healthy gut microbiome is essential for human wellbeing, this pathway of harm deserves attention alongside other known risks of microplastic exposure.
The Gut Microbiome in Foodborne Microplastic Toxicity: Mechanistic Insights and Human Health Risk Assessment
AI summary Read the abstract
This review pulls together existing research on how microplastics we eat, tiny plastic particles found in food and water, may disrupt the trillions of bacteria living in our gut, weakening the gut's protective barrier and triggering inflammation and stress throughout the body. It also points out that plastics can act like tiny rafts, carrying other harmful chemicals into our system and making the damage worse. While scientists don't yet have the full picture, this matters because it suggests the microplastics in our daily diet could be quietly affecting digestive and overall health, making this an area worth watching closely.
Gut microbiome remodeling induced by microplastic exposure in humans
AI summary Read the abstract
This review synthesizes evidence on how microplastic exposure affects the human gut microbiome, drawing on cross-sectional studies of people exposed through plastic food containers and other sources. Evidence indicates that microplastic exposure is associated with shifts in gut bacteria composition, including increases in certain bacterial groups linked to inflammation. The authors explore potential connections between microplastic-induced changes in gut bacteria and the development of various health conditions.
