Probiotics

In the context of human nutrition, probiotics are:

• Live microorganisms:
  • Specifically, these are bacteria and yeasts that, when consumed in adequate amounts, offer health benefits.  
• Beneficial to the gut:
  • They primarily work by influencing the balance of microorganisms in the gut microbiome.  
  • A healthy gut microbiome is crucial for various aspects of health, including digestion, immune function, and even mental health.  
• Found in foods and supplements:
  • Probiotics occur naturally in fermented foods like yogurt, kefir, sauerkraut, and kimchi.  
  • They are also available as dietary supplements in various forms, such as capsules, tablets, and powders.  
• Their role in health:
  • Probiotics can help maintain a healthy balance of gut bacteria, which can:
    • Improve digestion.  
    • Strengthen the immune system.  
    • Help prevent or treat certain digestive disorders.  

In essence, probiotics contribute to a healthy gut by adding beneficial microorganisms to the existing gut flora.

Are probiotics and prebiotics the same?

No, probiotics and prebiotics are not the same, though they work together to support a healthy gut. Here’s a simple way to understand the difference:  

• Probiotics:
  • These are live beneficial bacteria.  
  • They add to the population of good microorganisms in your gut.  
  • Think of them as the “good bacteria” themselves.
• Prebiotics:
  • These are non-digestible food ingredients, typically fiber.  
  • They act as food for the beneficial bacteria in your gut, helping them to grow and thrive.  
  • Think of them as “food for the good bacteria.”

In essence:

• Probiotics introduce good bacteria.  
• Prebiotics feed the existing good bacteria.  

Therefore, while both contribute to a healthy gut microbiome, they play different roles.
