Probiotics are live microorganisms that offer several benefits when ingested. They aid in digestion, weight loss, and, most importantly, the immune system. The human immune system is a series of biological structures and processes that protect the body from disease. There are several factors that contribute to a weakened immune system, such as eating unhealthy foods and living a sedentary lifestyle. However, one effective solution is taking probiotics. In this blog post, we’ll discuss how probiotics help boost the immune system.
What are Probiotics?
Probiotics are live microorganisms that are beneficial to the body. These organisms exist naturally in the body, and they’re also found in certain foods and supplements. Probiotics are made up of two main types of microorganisms: bacteria and yeast. Certain strains of these microorganisms are particularly advantageous to human health. Some of the most common strains used in supplements include Lactobacillus, Bifidobacterium, and Streptococcus Thermophilus.
How do Probiotics Boost the Immune System?
The immune system is incredibly complex, made up of many specialized cells and organs that work together to protect the body. One of the primary ways that probiotics improve the immune system is by supporting gut health. The gut is home to trillions of microorganisms called gut microbiota. These gut bacteria help break down food and absorb nutrients, and they also play a crucial role in overall health. When the gut microbiota is imbalanced, it can result in inflammation, allergies, and autoimmune diseases. Probiotics help maintain a healthy balance of gut microbiota by introducing beneficial microorganisms into the gut.
Introducing beneficial microorganisms into the gut can have several effects on the immune system. One such effect is an increase in the number of white blood cells and antibodies. These cells help fight off pathogens, such as viruses and bacteria, and keep the immune system functioning properly. Additionally, probiotics help reduce inflammation in the body. Chronic inflammation is linked to several diseases, including diabetes, heart disease, and cancer.
Another way that probiotics help boost the immune system is by promoting the production of antimicrobial peptides (AMPs). These peptides are naturally occurring substances that kill harmful bacteria and viruses. AMPs are found throughout the body, and they play an important role in the innate immune system, which is the body’s first line of defense against pathogens. Several studies have found that people who regularly consume probiotics have higher levels of AMPs.
The Benefits of Taking Probiotics for Immunity
While probiotics are beneficial for overall health, they’re particularly advantageous for the immune system. Research has shown that probiotics can help fight off illness and infection, especially respiratory infections. In a study of 240 adults, those who took a probiotic supplement had fewer colds and flu-like symptoms than those who did not. Another study found that probiotics can help reduce the risk of upper respiratory tract infections in marathon runners.
Probiotics may also be beneficial for individuals with autoimmune diseases. These diseases occur when the immune system mistakenly attacks healthy cells in the body. Probiotics help balance the gut microbiota and reduce inflammation, which may help reduce the severity of autoimmune symptoms.
Food Sources of Probiotics
While probiotic supplements are widely available, it’s also possible to get probiotics from food. Some of the best sources include fermented foods, such as yogurt, kefir, sauerkraut, and kimchi. These foods contain live cultures of beneficial bacteria that are similar to the strains found in supplements. In addition to containing probiotics, fermented foods also have several other health benefits, such as aiding digestion and promoting weight loss.
Conclusion
Probiotics are a simple and effective way to boost the immune system. By maintaining a healthy balance of gut microbiota, probiotics can increase the number of white blood cells and antibodies, reduce inflammation, and promote the production of antimicrobial peptides. They can also help fight off illness and infection and improve symptoms of autoimmune diseases. While probiotic supplements are widely available, it’s also possible to get probiotics from food. Consuming fermented foods is an excellent way to introduce beneficial microorganisms into the gut and improve overall health.
