Review: Fructose, the Sweet Culprit behind Nonalcoholic Fatty Liver Disease and Type 2 Diabetes

The composition of the diet has altered over the past few decades, with a significant increase in the consumption of dietary sugars, particularly fructose, which has risen more than tenfold. This elevated consumption of fructose and sugars is considered to be one of the major risk aspects for the emergence of obesity and other metabolic disorders. In this review, we discuss the correlation between insulin resistance and NAFLD (nonalcoholic fatty liver disease) due to dietary fructose intake. Type 2 Diabetes Mellitus (T2DM) is spreading quickly over the world and has epidemic proportions. The risk of both hepatic and metabolic abnormalities is increased by their connection, founded on shared metabolic risk factors such as obesity, (IR) Insulin Resistance, and an unhealthy standard of living. This review highlights the prevalence of coexisting T2DM (Type 2 diabetes) and NAFLD (Non-Alcoholic Fatty Liver Disease) in the community. In summary, the key pathophysiological pathways and risk stratification algorithms for the onset of nonalcoholic fatty liver disease and type 2 diabetes have been covered.
