KRT18 and type 2 diabetes mellitus: A prospective study by Markova et al. involving 37 subjects with NAFLD and type 2 diabetes, who were placed on an isocaloric diet rich in either animal or plant protein, demonstrated that, irrespective of the protein source, this diet resulted in a reduction in liver fat volume—furthermore, a reduction in the concentration of keratin-18 (an indicator of necroinflammation in the liver) was noted exclusively in the cohort of patients adhering to a plant protein-rich diet [50].
