Research Abstract

Obesity-and diabetes-related metabolic abnormalities, including insulin resistance, alterations in the IGF-1/IGF-1 receptor axis, state of chronic inflammation, and occurrence of adipokine imbalance, increase the risk of colorectal cancer and hepatocellular carcinoma. Therefore, improvement of these metabolic abnormalities by either pharmaceutical or nutritional intervention, such as supplementation with branched-chain amino acids, may be an effective strategy to prevent the development of colorectal cancer and hepatocellular carcinoma in obese individuals.
