Fiber in food (remnants): High fiber intake is associated with decreased risk of cancer, particularly colon cancer. Fiber acts by hastening bile acid excretion and diluting the concentration of carcinogens in the colon.
Selenium: Selenium, which is a mineral, is associated with decreased risk of multiple types of cancer.
Vitamins A, C, and E: These vitamins act as antioxidants, which neutralize free radicals that can cause cancer.
Omega 3 fatty acids: Omega 3 fatty acids present in fish oil are associated with decreased risk of cancer.
A diet rich in fruits and vegetables: A diet rich in fruits and vegetables is associated with reduced risk of various types of cancer. These foods contain antioxidants and other compounds that have protective effects against cancer.
