Additionally, the more fat you eat, the more bile that is produced. Bile is a fluid produced in the liver and excreted into the gut. There is some evidence that excess bile may cause cancerous changes in cells lining the colon. Like fruits and vegetables, grains and dry beans are good sources of fiber, vitamins, minerals, and other plant compounds that may offer protection against some cancers. There is no perfect food that can prevent cancer or supply all nutrients in amounts needed to stay healthy.
Foods contain combinations of nutrients and other healthful substances.
Therefore, eating a variety of fruits and vegetables, grains, and dry beans and limiting fat intake is recommended. Diet is only one factor in the cancer prevention picture. Eating only healthy foods is NOT a guarantee against getting cancer. This is not a yes or no question. It depends on the nutrient or substance in the vegetable.
