Colorectal cancer patients’ outcome in correlation with dietary and nutritional status: a systematic review

Abstract

Colorectal cancer (CRC) is one of the most common cancers worldwide and it involves various biomolecular and cellular levels. CRC has possibly happened due to aging, urbanization, and diet. Different foods have varying effects on the gastrointestinal cells, that's why additional research is necessary to create effective medical interventions. This review aimed to evaluate the correlation between dietary and nutritional status on the outcome of CRC patients. Study results showed that a healthy diet such as fruit and vegetables is the best diet for improving colorectal cancer outcomes. Moreover, nutritional status affected CRC patients' outcomes, where high BMI increases the risk of having CRC. However, low BMI was associated with CRC progression and poor quality of life.
