Diet plays a crucial role in cancer prevention. Consuming a variety of fruits, vegetables, and whole grains provides essential nutrients and antioxidants that help protect against cancer. Limiting the intake of processed foods, red meat, and sugary beverages can further reduce risk. Some foods, like those high in fiber, have been shown to lower the risk of colorectal cancer. Maintaining a healthy diet also aids in weight management, which is important since obesity is linked to several types of cancer.
