Based on the available information, it appears that while abstaining from alcohol can allow the liver to recover from damage to some extent, there is no clear evidence that diet alone can reverse the impact of alcohol on the liver.

According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), the liver can sometimes repair itself through a process called regeneration, where new cells grow to replace damaged or destroyed ones [2]. However, this process has its limits, and severe or long-term alcohol abuse can lead to irreversible scarring and damage, known as cirrhosis.

While there is some evidence that certain nutrients and dietary factors may support liver health and potentially aid in recovery, there is no scientific consensus that diet alone can reverse the effects of alcohol-induced liver damage [3][1].

Therefore, while maintaining a healthy diet can certainly benefit overall health and support liver function, it is not a substitute for abstaining from alcohol as the primary means of addressing alcohol-related liver damage.
