What percentage of cancer cases are influenced directly by diet?

The statement that approximately 70% of cancer cases are influenced directly by diet reflects the significant role that dietary factors play in the development of cancer. Research has shown that certain dietary patterns, including the consumption of fruits, vegetables, and whole grains, as well as the limitation of processed foods and red meats, can greatly impact cancer risk.

Multiple studies have indicated that food choices and dietary habits contribute to the risk of various types of cancer, particularly colorectal, breast, and prostate cancers. Nutrients from a well-balanced diet can support the body’s ability to repair DNA and maintain overall health, potentially reducing the risk of tumor development. Additionally, maintaining a healthy weight through diet is linked with lower cancer risk, as obesity is a known risk factor for several types of cancer.

Given this context, stating that 70% of cancer cases are influenced by diet aligns with the scientific consensus regarding the important connection between nutrition and cancer.
