There is increasing evidence suggesting that metabolic dysregulation associated with excessive dietary sugar intake may play a central role in colorectal carcinogenesis. Childhood obesity, impaired glucose metabolism and high consumption of sugar-sweetened beverages (SSBs) are prevalent among New Zealand youth, suggesting early metabolic dysfunction may precede and contribute to EOCRC risk. Given this, routinely measured metabolic biomarkers, including glucose and glycated haemoglobin (HbA1c), may offer early risk stratification within primary care settings.
