Dietary Polyamines and Diseases: Reducing Polyamine Intake Can Be Beneficial In Cancer Treatment

Abstract

Polyamines are most abundant polycationic natural amines and involved in several physiological processes. They can be supplied by the endogenous synthesis inside the cell or by the intake from exogenous sources. The polyamine content of cells is regulated by biosynthesis, degradation, uptake and excretion. The benefits of dietary polyamines can be changed; they may be harmful, neutral or beneficial. For example, increasing the amount of dietary polyamines is suggested during rapid growth, such as during the neonatal period, wound healing and after surgery. However, in cancer patients, reducing polyamine dietary intake has been shown to be beneficial on the quality of life. This review aimed to evaluate the effect of dietary polyamines in health and disease. Contribution/ Originality This study contributes in the existing literature by providing a detailed information on the importance of dietary polyamines in health and diseases. This study also highlights the beneficial impact of low polyamine diet on cancer treatment, and helps to increase awareness of daily polyamine intake regarding individual requirements.
