This post applies to both chronic and acute use of alcohol. Alcohol, specifically ethanol, can contribute to insulin resistance through several mechanisms, even though it does not directly result in insulin secretion. Here are the key mechanisms: 1. Oxidative Stress: alcohol consumption induces oxidative stress. These stresses can impair the function of pancreatic β-cells, which are responsible for insulin production and secretion. This impairment can lead to β-cell dysfunction and apoptosis, co
