Introduction
Probiotics are living microorganisms that provide numerous health benefits when consumed in adequate amounts. These good bacteria reside in our intestines and help in maintaining a balance between harmful and beneficial bacteria in our gut. Probiotics can be obtained through natural food sources like fermented foods or supplements. Along with promoting gut health, probiotics have also been found to play a vital role in boosting the immune system.
What are probiotics and how do they work?
Probiotics are live bacteria and yeasts that reside in our gut microbiome. They aid in digestion by breaking down food molecules, producing vital nutrients such as vitamins B and K, and regulating the pH balance of our gut environment. When the balance between harmful and beneficial bacteria in our gut is disturbed, leading to dysbiosis, we may experience several health issues ranging from digestive problems to compromised immunity.
Probiotics primarily work by supporting the integrity of our gut lining. The gut lining acts as a barrier, preventing harmful substances from entering our bloodstream. When the lining is compromised, potentially harmful substances leak into our bloodstream, causing inflammation and triggering immune responses. Probiotics help in increasing the production of mucus in our gut lining, strengthening the barrier against harmful substances, thereby preventing inflammation and strengthening the immune system.
The link between probiotics and immunity
The gut microbiome plays a crucial role in regulating our immune system. Gut bacteria have a direct impact on the development and functioning of immune cells, including T cells, B cells, dendritic cells, and natural killer cells. These immune cells play a vital role in defending our body against harmful pathogens like viruses and bacteria.
Several studies have suggested that consuming probiotics can help in boosting immunity. Probiotics have been found to enhance the production of antibodies, leading to increased resistance to infections. They also increase the phagocytic activity of immune cells, which help in clearing invading pathogens. Additionally, probiotics play a role in regulating the immune response, preventing overreaction against harmless substances and reducing the risk of autoimmune diseases.
Probiotics and respiratory infections
The respiratory system is constantly exposed to harmful pathogens, making it more susceptible to infections. Probiotics have been found to reduce the risk of respiratory infections, especially in children. Studies have shown that consuming probiotics during pregnancy and infancy can reduce the incidence of respiratory infections and decrease their severity.
A recent study found that consuming probiotics for at least three months can reduce the duration and severity of respiratory infections in adults. Probiotics work by enhancing the immune response in the respiratory tract, preventing the attachment of harmful pathogens to our lungs and reducing inflammation.
Probiotics and allergies
Allergies occur when our immune system overreacts to harmless substances, leading to inflammation and other symptoms like skin rashes, runny nose, and breathing difficulties. Probiotics have been found to regulate the immune response, preventing overreaction against harmless substances, thereby reducing the risk of allergies.
Several studies have demonstrated the effectiveness of probiotics in managing allergies. A study involving infants with eczema found that consuming probiotics could reduce the severity of eczema symptoms. Another study found that consuming probiotics during pregnancy and infancy could reduce the risk of developing allergies in children.
Conclusion
Probiotics play a crucial role in promoting gut health and boosting immunity. They work by supporting the integrity of our gut lining, enhancing the immune response, and preventing overreaction against harmless substances. Incorporating probiotics into our diet or taking supplements can improve our overall health and reduce the risk of infections, respiratory illnesses, and allergies.
