Probiotics are live microorganisms that provide many health benefits when consumed in adequate amounts. They are often referred to as “good bacteria” and are commonly found in fermented foods like yogurt, kimchi, and sauerkraut.
The benefits of probiotics are well-known and extensive, and their effects on the immune system are no exception. Here are 10 ways that consuming probiotics can improve your body’s defenses.
1) Reduce the risk of infections
Consuming probiotics regularly can help reduce the risk of infections caused by bad bacteria, viruses, and fungi. They can also help reduce the duration and severity of infections like the common cold, influenza, and stomach flu.
2) Enhance the production of antibodies
Probiotics can stimulate the production of antibodies, which are proteins that recognize and fight harmful pathogens. These antibodies can help the body fight off infections before they become too severe, and they can also help prevent future infections from occurring.
3) Regulate the immune response
Probiotics can help regulate the immune response to prevent harmful inflammation that leads to conditions like Crohn’s disease, ulcerative colitis, and rheumatoid arthritis. They can also help reduce the chances of allergies and autoimmune diseases by improving the gut barrier function.
4) Increase the activity of natural killer cells
Natural killer (NK) cells are a type of white blood cell that helps the body fight off cancer and viral infections. Probiotics can enhance the activity of NK cells, thereby helping the body eliminate cancerous or infected cells more effectively.
5) Improve the gut microbiota
Probiotics can help improve the balance of the gut microbiota by enhancing the growth of good bacteria and preventing the overgrowth of bad bacteria. A healthy gut microbiota has been linked to weight loss, mental health, and of course, immune health.
6) Stimulate the mucosal immune system
Probiotics can boost the production of secretory IgA, a type of antibody that helps reinforce the gut mucosa. This reinforcement helps trap harmful bacteria and toxins, and prevent them from entering the bloodstream or other parts of the body.
7) Improve lung function
Probiotics can improve lung function by preventing harmful inflammation that can trigger asthma, emphysema, and other respiratory conditions. They can also help reduce the frequency and severity of respiratory infections.
8) Enhance vaccine response
Probiotics can enhance the immune response to vaccines, making them more effective. They can also help reduce adverse side effects like fever or pain that can occur after vaccination.
9) Prevent urinary tract infections
Probiotics can help prevent urinary tract infections by balancing the vaginal microbiota. They can also help reduce the recurrence of these infections among women who experience them frequently.
10) Boost wound healing
Probiotics can boost wound healing by improving the activity of immune cells and stimulating the production of growth factors that help repair damaged tissues. They can also help prevent infections in wounds, reducing the risk of complications.
All these benefits make probiotics an essential part of a healthy immune system. You can get probiotics from fermented foods and supplements. Be sure to consume a variety of probiotic strains, as each strain has unique benefits for your health.
