Relación entre consumo de alimentos procesados, ultraprocesados y riesgo de cáncer: una revisión sistemática

Abstract

Diet is a modifiable risk factor for the development of cancer. Consumption of processed and ultra-processed foods has been associated with an increased risk of chronic non-communicable diseases. The objective of this review is to systematically evaluate the published evidence on the relationship between the consumption of processed and ultra-processed foods with the development of different types of cancer. A systematic review of the Pubmed database was carried out for articles published in the last 10 years. Cohort, case-control or cross-sectional studies that evaluated cancer risk in adults, no cancer recurrence, and studies that evaluated diet through surveys or dietary patterns were included. Two authors independently reviewed titles and abstracts to select articles, and subsequently carried out a text review. Data was extracted and the methodological quality was analyzed of the included studies. The results contemplate the conclusions of 18 studies, four cohort studies, 13 case-control and one cross-sectional. Fourteen of the included studies showed a positive association between the intake of processed and ultra-processed foods and the development of cancer.
