Risk reduction involves making modifications to one's behavior and lifestyle choices to decrease the likelihood of adverse health outcomes. For instance, adjusting diet, increasing exercise, or quitting smoking are all lifestyle changes aimed at reducing the risk of noninfectious diseases such as cardiovascular diseases, type 2 diabetes, and certain types of cancer.
