Step-by-step explanation:
Nutrition relates to cancer in two main ways: through the promotion or prevention of cancer growth.
1. Promotion of cancer growth: Certain food substances and cooking processes have been linked to an increased risk of developing cancer. For example, alcohol consumption is associated with an increased risk of various cancers including mouth, throat, liver, and breast cancer.
2. Prevention of cancer growth: Good nutrition can help reduce the risk of developing cancer. Consuming a diet rich in fruits, vegetables, whole grains, and lean protein can provide essential nutrients and antioxidants that help protect against cancer.
