6 Surprising Ways Probiotics Boost Your Immune System
Probiotics are live bacteria and yeasts that are good for your health, especially for your digestive system. They are often called “good bacteria” because they help keep your gut healthy. But did you know that probiotics can also boost your immune system? Here are six surprising ways probiotics can improve your body’s defense system.
1. Probiotics can prevent respiratory infections
Studies have shown that probiotics can help prevent respiratory tract infections, such as the common cold, flu, and pneumonia. Researchers believe this is because they stimulate the production of antibodies and enhance the activity of immune cells in the respiratory tract. In fact, a review of 10 clinical trials found that taking probiotic supplements reduced the incidence of upper respiratory infections by 42%.
2. Probiotics can reduce inflammation
Inflammation is a natural response of the body to infection or injury, but chronic inflammation can lead to diseases such as arthritis and diabetes. Probiotics have been shown to reduce inflammation by reducing the production of pro-inflammatory cytokines and increasing the production of anti-inflammatory cytokines. In one study, women who took a probiotic supplement for 12 weeks had lower levels of inflammation than those who took a placebo.
3. Probiotics can improve vaccine effectiveness
Vaccines work by stimulating the immune system to produce antibodies against a specific disease. Probiotics can enhance the effectiveness of vaccines by increasing the production of these antibodies. In one study, children who took a probiotic supplement had a higher immune response to the flu vaccine than those who took a placebo.
4. Probiotics can prevent and treat vaginal infections
Probiotics can help maintain the balance of bacteria in the vagina and prevent infections such as bacterial vaginosis and yeast infections. They do this by producing lactic acid, which creates an acidic environment that is hostile to harmful bacteria. In one study, women who took a probiotic supplement had lower rates of bacterial vaginosis and yeast infections than those who did not.
5. Probiotics can improve gut barrier function
The gut barrier refers to the lining of the digestive tract, which prevents harmful substances from entering the bloodstream. Probiotics can improve gut barrier function by strengthening the tight junctions between the cells of the gut lining. This can reduce the risk of leaky gut syndrome, which has been linked to autoimmune diseases such as rheumatoid arthritis and multiple sclerosis.
6. Probiotics can reduce allergies and asthma
Allergies and asthma are caused by an overactive immune response to harmless substances such as pollen and dust. Probiotics can reduce allergies and asthma by modulating the immune response and reducing inflammation. In one study, children who took a probiotic supplement for six months had a significant reduction in eczema, a common allergic skin condition.
Overall, probiotics are a safe and effective way to boost your immune system and improve your overall health. They are available in supplement form and can also be found in fermented foods such as yogurt, kefir, and kimchi. If you are considering taking probiotics, talk to your healthcare provider to determine which strain and dosage is right for you.
