Introduction

Ever wondered why your grandmother insisted on curd rice during summers or gave you a spoon of pickle with every meal? Turns out, she wasn’t just being traditional—she was feeding your gut! 
In Indian households, fermented and fibre-rich foods have long played a quiet but powerful role in supporting health. While modern wellness trends embrace probiotics through pills and kombucha, our kitchens have always been home to naturally gut-friendly ingredients passed down through generations. 

This blog is a tribute to those humble Indian dishes that your body (and your gut bugs) absolutely love. These are the unsung heroes on our plates, lovingly prepared and loaded with health-promoting microbes and prebiotic fibres. So, the next time you reach for that glass of buttermilk or plate of idli, know that you’re not just enjoying comfort food—you’re nourishing your second brain: the gut. 

Curd (Dahi) 

Let’s start with the OG. Curd is that cool, creamy bowl of comfort that’s not just soothing but full of life—literally! It’s packed with friendly bacteria like Lactobacillus delbrueckii subsp. bulgaricus, Streptococcus thermophilus, and sometimes even Lactobacillus acidophilus, which support digestion and help keep the gut balanced. 

Scientific Backing: According to Kumar et al. (2012), curd helps lactic acid bacteria flourish, creating a gut environment that keeps harmful microbes in check. Regular consumption of dahi can help maintain microbial balance in the intestines and promote better nutrient absorption. 

Buttermilk (Chaas) 

That post-lunch chaas your mom made? It’s more than a refreshing drink—it’s a probiotic powerhouse. Especially when seasoned with jeera and ginger, it helps digestion, cools the body, and nourishes your gut. Common microbes native to chaas include Lactobacillus casei, Lactobacillus lactis, Lactococcus lactis, and Leuconostoc mesenteroides

Scientific Backing: Fermented dairy like buttermilk improves microbial diversity and can calm gut inflammation (Chaudhary et al., 2018). It can also be especially soothing in hot climates and support hydration along with digestive health. 

Pickles (Traditional Fermented Achaar) 

Not the store-bought ones swimming in vinegar, but the homemade, sun-kissed kind your naani made. These are loaded with beneficial microbes like Leuconostoc mesenteroides, Lactobacillus plantarum, and Lactobacillus brevis that do wonders for your gut health. These pickles, made through natural fermentation, are not only tangy and delicious but also a microbial feast.

Scientific Backing: Das et al. (2016) showed that traditionally fermented pickles can diversify your gut microbiome and offer antioxidant benefits. Their regular consumption has also been associated with improved digestion and immune modulation. 

Idli and Dosa (Fermented Rice & Lentil Batter) 

Soft, fluffy idlis and crisp dosas aren’t just breakfast goals—they’re microbiome magic. The fermented batter is full of good bacteria that enhance nutrient absorption and aid digestion. Common microbes in the most popular breakfasts are Lactobacillus fermentum, Leuconostoc mesenteroides, Streptococcus faecalis, and Pediococcus cerevisiae

Scientific Backing: Rawat et al. (2018) found that these foods encourage production of short-chain fatty acids (SCFAs), which are key to gut and colon health. SCFAs like butyrate also help lower inflammation and support the intestinal barrier. 

Kanji (Fermented Carrot or Beet Drink) 

That tangy, magenta-hued winter drink? It’s kanji, and it’s quietly working behind the scenes to improve your gut diversity. Made by fermenting carrots or beets with mustard seeds, kanji is a seasonal favourite with potent probiotic benefits. Common microbes found in kanji are Lactobacillus fermentum, Lactobacillus brevis, Lactobacillus paraplantarum, and native yeasts like Saccharomyces cerevisiae

Scientific Backing: Ray et al. (2016) highlighted kanji’s ability to restore microbial balance post-antibiotic use and deliver antioxidant power. It’s a traditional detoxifier that doubles up as a gut-health enhancer. 

Lentils and Pulses (Dal, Rajma, Chana) 

Your dal-chawal isn’t just comfort food—it’s gut food. Pulses are rich in fiber and resistant starches that act as prebiotics, feeding your gut bacteria and helping produce SCFAs. During fermentation, legumes promote the growth of Bifidobacteria, Lactobacilli, and production of SCFAs like butyrate and propionate. These humble ingredients play a foundational role in most Indian diets and are quietly nourishing your gut lining, improving bowel regularity, and supporting a balanced microbiota. 

Scientific Backing: According to Ray & Swain (2016), fermentation of legumes boosts amino acid availability and supports colon health by increasing SCFA production. Their regular inclusion in meals offers a steady source of fuel for beneficial gut microbes. 

Conclusion 

Our grandparents didn’t need fancy labels to eat healthy—they trusted their thalis. And turns out, they were spot on. From creamy curd to crunchy pickles, our traditional foods are deeply nourishing, especially for the gut. 

Next time you have idli for breakfast or sip on buttermilk, remember—you’re doing something amazing for your microbiome. By embracing these humble dishes, you’re not just enjoying taste and tradition, but actively promoting better digestion, stronger immunity, and overall wellbeing. 

Note: The microbial strains listed in this blog are based on scientific studies that analyzed traditional Indian fermented foods. Since these foods are often made using natural, spontaneous fermentation methods, the dominant microbes may vary slightly depending on region, climate, ingredients, and preparation style. But across the board, they deliver beneficial effects for gut health.
