Cullen Nutrition Simplified - Probiotics Need Prebiotics: Here’s Why It Matters


We hear a lot about probiotics for gut health, but here’s the thing: they can’t work their magic without the right food. That’s where prebiotics come in!

Prebiotics are a type of fibre that feed the good bacteria (probiotics) in your gut, helping them grow and thrive. Without them, probiotics may not stick around long enough to do much good.

Here’s how it works:

-Prebiotics are found in foods like garlic, onions, bananas, and whole grains. Think of them as the fuel probiotics need to survive.

-Probiotics are in fermented foods like yogurt, kefir, and sauerkraut. These good bacteria support digestion, immunity, and overall gut health.

When you get both prebiotics and probiotics in your diet, they work together to keep your gut in balance. Think of it as a team effort—prebiotics set the stage so probiotics can do their thing.

So, if you’re taking probiotics or eating probiotic-rich foods, don’t forget to add some prebiotic-rich ones too. It’s a simple step that can make a big difference for your gut!
