Researchers have discovered that casein glycomacropeptide (CGMP), a specific protein fragment found in milk, can restore the intestinal mucosal barrier. This barrier is often compromised by a `Western-style` diet, which is high in fats and sugars but low in fiber. Experiments on mice showed that supplementing with this milk component stimulated the growth of the protective layer, preventing microbes from penetrating the intestinal walls. The findings were published in the journal Food Research International (FRI).
The most pronounced effect was observed with a CGMP variant rich in sialic acid. It not only restored the mucous membrane but also promoted the proliferation of beneficial bacteria, such as bifidobacteria. Simultaneously, the body`s levels of short-chain fatty acids increased, which are crucial for strengthening the gut barrier and reducing inflammatory processes.
The study`s authors suggest that this milk component could be considered a promising prebiotic. In the future, it may help mitigate the harm caused by unbalanced diets and reduce the risk of chronic intestinal diseases. However, these conclusions are currently based solely on animal studies, and clinical trials are needed for human application.
Previously, scientists also found that yak milk can protect the brain from damage caused by chronic alcohol consumption.
