6 simple, everyday postbiotic switches you didn’t even know you needed

Postbiotics = beneficial by-products of fermentation ?✅ Some of these switches could be small habits which build up to give big wins, and here I explain why… 1. Brown bread ➡️ sourdough Ever wondered what gives ‘sour’dough that distinctive tangy taste? All the postbiotics of course, many of which are organic acids. There are so many delicious varieties out there these days too. Sundried tomato, anyone? ? 2. Coleslaw ➡️sauerkraut Much healthier, plus, tastier in my book, and packed with probiotics and their beneficial by-products, postbiotics ? 3. Stir-fry sauce ➡️ soy sauce Pre-packaged sauces are often loaded with sugar, so it’s a win-win to swap those out, for a naturally fermented alternative. 4. Stock cubes ➡️ miso paste Miso paste is my new obsession. Fermented goodness which will add maximum flavour to any meal. Must try! 5. Processed yoghurt dupes ➡️Kefir (Natural or authentic yoghurts are fine also !) Ever really read those yoghurt tubs? ‘Flavoured’ ‘low-fat’ and ‘Greek-style’ are all red flags for me. Go for the sour tasting, properly fermented options instead. 6. Squash ➡️ Molkosan The simplest swap, but possibly the most beneficial of all. Molkosan is a postbiotic powerhouse. Skip large intakes of artificially sweetened squashes, and feel the difference by supporting your gut daily instead.

6 Simple, Everyday Postbiotic Switches You Didn’t Even Know You Needed 

Postbiotics are the beneficial compounds produced during fermentation. While probiotics often steal the spotlight, postbiotics are the powerful by-products that can help support gut health and overall wellbeing.

The best part? Supporting your postbiotic intake doesn't have to mean a complete diet overhaul. Sometimes it's the small, everyday swaps that add up to make a real difference over time. Here are six simple switches worth trying:

1. Brown Bread ➡️ Sourdough 

Ever wondered what gives sourdough its distinctive tangy flavour? That's fermentation at work. During the fermentation process, beneficial compounds including organic acids are produced, contributing to both its taste and its postbiotic content.

Sourdough has become incredibly versatile too, with delicious varieties available everywhere. Sundried tomato sourdough, anyone? 

2. Coleslaw ➡️ Sauerkraut

In my opinion, this is one of the easiest upgrades you can make. Swap creamy, processed coleslaw for naturally fermented sauerkraut and you'll be getting a food that's rich in probiotics and their beneficial by-products, postbiotics.

It's crunchy, flavourful, and a fantastic addition to salads, sandwiches, or alongside your favourite meals. 

3. Stir-Fry Sauce ➡️ Soy Sauce 

Many pre-packaged stir-fry sauces can be surprisingly high in sugar and additives. A naturally fermented soy sauce offers a simpler alternative that still delivers plenty of flavour.

It's a small change that can help cut down on unnecessary ingredients while introducing more fermented foods into your routine.

4. Stock Cubes ➡️ Miso Paste 

Miso paste is my current kitchen obsession. Made through a traditional fermentation process, it's packed with rich umami flavour and can transform soups, sauces, dressings, and even roasted vegetables.

A spoonful goes a long way, making it an easy and delicious way to bring fermented goodness into everyday cooking.

5. Processed Yoghurt Dupes ➡️ Kefir (or Authentic Natural Yoghurt) 

Have you ever taken a closer look at some yoghurt labels? Terms like "Greek-style," "flavoured," or "low-fat" can often signal a more processed product with added ingredients.

Instead, choose properly fermented options such as natural yoghurt or kefir. Their characteristic tangy taste is a good clue that fermentation has done its job, providing beneficial bacteria along with valuable postbiotic compounds.

6. Squash ➡️ Molkosan 

This may be the simplest switch of all, but potentially one of the most impactful. Instead of regularly reaching for artificially sweetened squashes, consider adding Molkosan to your daily routine.

Derived from fermented whey, Molkosan is a postbiotic powerhouse that can help support a healthy gut environment. Small daily habits often create the biggest long-term benefits, and this is one that's easy to stick with.

The Bottom Line 

You don't need a perfect diet to support your gut health. Simple swaps like choosing sourdough over standard bread, sauerkraut over coleslaw, or kefir over heavily processed yoghurt alternatives can gradually increase your intake of beneficial fermented foods and postbiotics.

Small changes, repeated consistently, can have a surprisingly big impact over time. Which swap are you trying first?
