Many food products contain engineered nanoparticles (ENPs) due to both unintentional and intentional additions. There has been increasing concerns about the potential health risks associated with foodborne ENPs. However, the detailed understanding of health effects of foodborne ENPs is not available despite a limited number of published toxicity studies on these ENPs. This talk provides an overview on our recent studies on the health effects of organic and inorganic foodborne ENPs, i.e. nanoemulsions and titanium dioxide nanoparticles, respectively. Specifically, the impacts of these ENPs on systemic toxicity, bioavailability and metabolism of food components, homeostasis of gut microbiome will be discussed.
