Kefir: a powerful fermented milk drink for the prevention of non-communicable diseases

Kefir is a fermented milk beverage rich in probiotics. This product with ancient origins is becoming increasingly popular nowadays due to its beneficial effects on human health. The gut microbiota has recently been shown to play an important role in regulating many different biological aspects such as nutrients absorption, immune regulation, and neuronal transmission. It follows that by regulating the composition of the gut microbiota, individual health can be significantly influenced. This study aims to show how kefir, as part of a healthy diet and lifestyle, can help prevent non-communicable diseases. It has been shown that regular consumption of kefir can increase insulin sensitivity in individuals at high risk of developing type 2 diabetes mellitus. Kefir also helps reduce inflammation and regulates the accumulation of cholesterol in the arteries, preventing the risk of atherosclerosis. Recently, promising results have been found on the effect of kefir in limiting the growth and development of cancer cells.
