Scientists find link between sugar metabolism and alcohol addiction

Scientists discovered that alcohol triggers a metabolic pathway that produces fructose, which may reinforce alcohol consumption and accelerate liver damage.

Why it matters

  • Identifies a potential new therapeutic target for treating alcohol-associated liver disease (ALD) and alcohol use disorder (AUD).
  • Shows that alcohol affects the body's sugar metabolism, enhancing drinking behavior and worsening liver injury.

By the numbers

  • Study conducted on mice showed those lacking KHK drank less alcohol and had reduced liver damage.
  • Findings suggest targeting fructose metabolism could benefit patients with liver disease linked to diet or alcohol use.

The big picture

  • Discovery highlights an unexpected intersection between sugar and alcohol metabolism.
  • Opens possibilities for developing treatments targeting a common pathway underlying both metabolic and alcohol-related liver diseases.

What they're saying

  • Connection between alcoholism and sugar seeking is not surprising given evolutionary context.
  • Finding might explain why GLP-1 inhibitors are effective at reducing alcohol cravings.

Caveats

  • Study conducted on mice; effects in humans might differ.
  • Findings promising but need further research to develop effective treatments.

What’s next

  • Further research needed to see if findings translate to humans.
  • Developing therapies targeting fructose metabolism could help treat alcohol addiction and liver disease.
