Fermented foods are not only delicious but also packed with probiotics that promote gut health. These friendly bacteria support digestion, boost your immune system, and improve overall well-being. Best of all, you can easily make many probiotic-rich foods at home with a few basic tools. In this guide, we’ll explore the top 10 probiotic foods you can ferment in your kitchen and how to get started.
Fermented foods have been consumed for thousands of years across different cultures, as noted in this comprehensive overview from the NCBI.
What Are Probiotics and Why Are They Important?
Probiotics are live microorganisms, primarily bacteria, that offer health benefits when consumed in the right amounts. Fermented foods provide a natural source of these beneficial bacteria, which can balance the gut microbiome, improve digestion, and even enhance mental health. Probiotics are live microorganisms that provide health benefits, particularly for digestive and immune health, as shown in research from Harvard Health.
