The Role of Probiotics & Prebiotics in Everyday Nutrition → Practical insights on feeding your microbiome for better health.
What are probiotics?
Probiotics are live microorganisms—mainly bacteria and some yeasts—that, when consumed in adequate amounts, deliver health benefits by helping maintain a healthy balance in your gut. The most common probiotic species found in foods and supplements are from the Lactobacillus and Bifidobacterium families. These “good bugs” often come in fermented foods like yogurt, kefir, kimchi, and certain cheeses, and also in capsule or powder form.
What are prebiotics?
Prebiotics are a type of fiber and other food components that humans can’t digest, but your gut bacteria can. Simply put, they’re the “food” for probiotics and other beneficial gut microbes. Common prebiotics include ingredients found in garlic, onions, bananas, leeks, asparagus, and wholegrains. When you eat prebiotics, they travel through your digestive system to your colon, where they help your healthy bacteria grow and flourish.
What is a synbiotic?
A synbiotic blends both probiotics and prebiotics in the same product—think ofit as a teamwork formula. By providing beneficial bacteria alongside thefood they need, synbiotics aim to maximize the survival and activity ofprobiotics in your gut.
Why is it important to take probiotics/How do probioticsimpact your health?/What health outcomes are affected by probiotics and how?
Probiotics influence your health in a variety of ways:
It’s worth noting that health effects are strain- and condition-specific—that means not all probiotics have the same effect, and their impact can vary depending on your own health.
What is the concept of personalised probiotics and why does it matter?
The idea of personalised probiotics comes from the realization that everyone’s gut microbiome is unique. Factors like your diet, environment, genetics, and existing gut bacteria mean that what works for one person may not benefit another. Personalised probiotic formulas, created using gut microbiome tests or tailored to local diets, could help ensure you get the strains most suitable for your needs—boosting efficacy and reducing the chance of taking an ineffective product.
