Which of the following is a common symptom of foodborne illness?

Nausea and vomiting are typical symptoms of foodborne illness because these reactions occur as the body's response to harmful pathogens or toxins that have been ingested. When contaminated food is consumed, the digestive system can react by trying to expel the harmful substances, leading to nausea and vomiting. This is known as a protective mechanism that aims to rid the body of the offending agents.

In contrast, symptoms like increased energy levels, clear skin, or a heightened sense of taste do not align with the physiological responses to foodborne illness. These options do not represent typical reactions that one would expect in cases where food contamination has occurred. Understanding these reactions is crucial for recognizing and managing foodborne illnesses effectively.
