What is the role of probiotics in nutrition?

Probiotics play a crucial role in nutrition primarily by being beneficial bacteria that support gut health and digestion. They are live microorganisms, often referred to as "good" bacteria, that contribute positively to the balance of the gut microbiota. This balance is essential for maintaining digestive health, as it aids in the breakdown and absorption of nutrients, helps prevent gastrointestinal issues such as constipation, diarrhea, and bloating, and may even influence metabolism.

In addition to supporting digestion, probiotics can also enhance the gut barrier function, which is important for preventing harmful bacteria and toxins from entering the bloodstream. A healthy gut microbiome, bolstered by probiotics, can also support the body's immune function, helping to protect against infections and inflammatory diseases. Overall, their role in fostering a balanced gut environment underlines their significance in a healthy diet.
