What lifestyle change is NOT recommended for cancer prevention?

The option that is not recommended for cancer prevention is regular consumption of processed foods. Consuming a diet high in processed foods has been associated with various negative health outcomes, including an increased risk of developing several types of cancer. Processed foods often contain high levels of unhealthy fats, sugars, and additives that can contribute to obesity and metabolic disorders, both of which are recognized risk factors for cancer.

In contrast, quitting smoking, maintaining physical activity, and following a diet rich in fruits and vegetables are all positively associated with cancer prevention. Quitting smoking significantly reduces the risk of cancers, especially lung cancer, as smoking is one of the leading causes of cancer mortality. Regular physical activity helps maintain a healthy weight and can reduce the risk of certain types of cancer, such as breast and colon cancer. A diet rich in fruits and vegetables provides essential nutrients and antioxidants that may help protect against cancer by limiting oxidative stress and inflammation.

Therefore, the best approach to reduce cancer risk includes avoiding processed foods and promoting healthier lifestyle choices.
