ClearToxicity of metal-based nanoparticles: Challenges in the nano era
This review covers the toxic effects of metal-based nanoparticles on human health, including how they cause oxidative stress, inflammation, DNA damage, and organ dysfunction. While focused on engineered nanoparticles rather than microplastics directly, the toxicity pathways described overlap significantly with those triggered by nanoplastic exposure. Understanding these shared mechanisms helps explain how nano-scale particles of any kind, including nanoplastics, may harm the body.

A systematic review on the effects of nanomaterials on gut microbiota
This systematic review of 68 studies found moderate evidence that zinc-based, copper-based, and silver nanomaterials cause gut microbiota dysbiosis, while titanium dioxide nanoparticles showed variable effects depending on crystal form and dose. The gut microbiome's response to nanomaterials depended heavily on particle composition, size, dose, and exposure duration. These findings are directly relevant to microplastic research, as ingested micro- and nanoplastics similarly interact with gut bacteria and may alter the microbiome composition that influences immune function and overall health.
Nanoparticles in food: formation during cooking, migration from packaging, and nanoplastics release—food safety implications
This review examines how nanoparticles form in food during cooking, migrate from packaging materials, and are released as nanoplastics during food preparation. Researchers found that high-temperature cooking generates fluorescent carbon nanoparticles, while nanosilver transfers from packaging into food at rates that increase with temperature and storage time. The study highlights the need for standardized methods and long-term exposure research to fully understand the health implications of nanoparticles in our food supply.

Is There Evidence of Health Risks From Exposure to Micro- and Nanoplastics in Foods?
This review examines the evidence for health risks from micro- and nanoplastic exposure through food, noting that plastic particles can carry physical, chemical, and biological hazards. The study suggests that ingested plastics could contribute to inflammation, oxidative stress, and immune responses, and may even influence food allergy development by altering gut permeability and intestinal microbiome balance.
A review on microplastics and nanoplastics in the environment: Their occurrence, exposure routes, toxic studies, and potential effects on human health
This review summarizes what is known about how microplastics and nanoplastics enter the human body through food, air, and skin contact, and what they do once inside. Studies on cells and animals show these tiny particles can cause oxidative stress, DNA damage, inflammation, and harm to the immune, digestive, reproductive, and nervous systems. The research makes clear that microplastics are not just an environmental problem but a direct concern for human health.

This study reviews the primary exposure pathways through which microplastics and nanoplastics enter the human body—via drinking water, food, air, and household sources—and examines their toxic mechanisms across the digestive, respiratory, cardiovascular, reproductive, and immune systems.
Potential health risks of nanomaterials in food: a methodology to identify signals and prioritise risks
This Dutch report assessed the potential health risks of nanomaterials in food, evaluating existing methods for detecting and evaluating the safety of engineered nanoparticles. As nanoplastics increasingly enter the food supply through packaging and environmental contamination, frameworks for their risk assessment become critical.

This review summarizes the current state of knowledge about micro- and nanoplastic contamination in food, covering sources, occurrence, and analytical detection methods. Researchers found that while various foods, especially seafood, contain measurable levels of microplastics, the health risks to humans remain difficult to assess due to inconsistent research methods. The study calls for standardized approaches to better evaluate dietary exposure and potential health impacts.
Toxic Effect of Food-Borne Microplastics on Human Health
This review compiles evidence that people ingest thousands of microplastic particles annually through everyday foods including drinking water, salt, fish, tea, and milk, and that these particles can cause cytotoxicity, inflammation, hormone disruption, and even neurotoxicity in experimental models. Microplastics can cross the gut lining and enter the circulatory system, potentially affecting organs throughout the body. The paper serves as a comprehensive summary of the known and suspected human health risks from food-borne microplastic exposure.

This review assesses the potential for micro- and nanoplastics to enter the human food chain, drawing on evidence from studies of food production and related biological systems. Researchers found that while larger microplastics are unlikely to be absorbed by the human body, nanoplastics may be small enough to cross biological barriers and accumulate in tissues. The study highlights that much remains unknown about real-world human exposure levels and calls for more research into the health implications of these tiny particles in food.
