Fermented foods are trending, but they're not new. 🥬
Foods like yoghurt, kefir, kimchi, sauerkraut and miso have been eaten for centuries. Originally used for food preservation, they're now gaining attention for their potential gut health benefits.
Here's what the science says:
• Many fermented foods contain live microbes and bioactive compounds produced during fermentation, both of which may support gut microbiome diversity and help reduce inflammation. But not all fermented foods are equal: pasteurised, shelf-stable or heavily cooked products may no longer contain live cultures.
• Benefits likely come from more than just live bacteria. Fermentation also produces bioactive peptides, short-chain fatty acids and other metabolites that may contribute to gut and immune health.
Easy ways to add them to your day:
• Kefir in smoothies, overnight oats or chia pudding
• Yoghurt with fruit, nuts and seeds
• Sauerkraut or kimchi (unpasteurised) with eggs, grain bowls or sandwiches
• Miso stirred into soups or dressings at the end, off the boil, to preserve live cultures
Look for products labelled "unpasteurised," "raw" or "contains live cultures" if you're after the live microbe benefit.
There's no official guideline on how much to eat, but including fermented foods regularly alongside a diverse, fibre-rich diet is a sensible approach to supporting your gut. ✨
