Diet plays a crucial role in toxicology as it can influence the body's exposure to and metabolism of toxins. Eating a balanced diet rich in fruits, vegetables, and whole grains provides essential nutrients and antioxidants that help protect the body against oxidative stress caused by toxins. Additionally, some foods can enhance the body's natural detoxification processes. For example, cruciferous vegetables like broccoli and Brussels sprouts contain compounds that activate liver enzymes involved in detoxifying harmful substances.
