Protective responses to food-borne microbes include the activation of the immune system, which produces antibodies and immune cells to combat pathogens. The gastrointestinal tract also employs physical barriers, such as mucus and stomach acid, to inhibit microbial growth. Additionally, the gut microbiota plays a crucial role in outcompeting harmful microbes and enhancing gut health. Lastly, vomiting and diarrhea serve as immediate reflexes to expel harmful substances from the body.
