Switzerland, May 14: Researchers at ETH Zurich have developed a groundbreaking protein-based gel that can significantly mitigate the harmful effects of alcohol by breaking it down into harmless acetic acid within the gastrointestinal tract.
This innovative solution could revolutionize how we manage alcohol consumption and its associated health risks.
The gel, detailed in a recent study published in Nature Nanotechnology, is particularly effective in preventing alcohol from entering the bloodstream and causing intoxication or longer-term damage. Professor Raffaele Mezzenga from the Laboratory of Food & Soft Materials at ETH Zurich explained the mechanism: “The gel shifts the breakdown of alcohol from the liver to the digestive tract. In contrast to when alcohol is metabolised in the liver, no harmful acetaldehyde is produced as an intermediate product.”
The research team utilized simple whey proteins combined with iron atoms and gold nanoparticles to create this gel.
The gel acts through a cascade of enzymatic reactions initiated by these components to convert alcohol into acetic acid before it can be absorbed into the blood.
This process not only prevents intoxication but also reduces the burden on the liver and other organs.
In experiments with mice, the gel reduced blood alcohol levels by up to 56 per cent within five hours of alcohol consumption.
It also showed potential for long-term protective effects, such as reduced liver damage and improved overall health indicators in the subjects.
While the gel is still pending patent approval and requires further clinical trials before it can be authorized for human use, the researchers are optimistic about its potential.
Jiaqi Su, the first author of the study, noted, “We immersed the fibrils in an iron bath, so to speak, so that they can react effectively with the alcohol and convert it into acetic acid.”
This innovation could be a significant step forward in managing the health risks associated with alcohol consumption, offering a practical solution for those who consume alcohol but wish to mitigate its effects.
