  • South Indian fermented foods offer gut health benefits
  • Idli, dosa, and sambar are nutritious, protein-rich options
  • These foods are under-marketed despite their health advantages

Wellness trends may be hailing fermented foods now for their gut health benefits, but in South India, they have been an ancient practice, evident in the diet people enjoy. Rice, lentils, millets, coconut, and fermentation have been part of the tradition for generations, and these ingredients and culinary practices are known to support nutrition and protect the gut.

Fortis gastroenterologist Dr Shubham Vatsya took to his Instagram account and explained the power of simple South Indian foods that are usually not promoted as often. “South Indians are very poor marketing agents of their own foods, despite the fact that they have some of the healthiest fermented foods,” he said.

He highlighted how these foods are not talked about as much as gravies or platters that are heavily laden with butter or ghee. “We drool over butter-loaded gravies and tandoori platters, calling them “healthy,” while ignoring one of the smartest cuisines in the world, South Indian food,” he added.

Dr Vatsya hailed idli as one of the best fermented foods. For sambar, he suggested adding vegetables, as the combination makes it both protein- and fibre-rich. He called it a naturally well-balanced dietthat’s also clean and plant-forward.

For dosa lovers, he advised, “If you cook dosa in oil without over-frying it and replace potato with paneer, then you have a great vegetarian option: fermented dosa with protein.” He called all of these as excellent options for fermented foods. These are excellent for your gut health.

“Dosa, idli, sambar… naturally fermented, low-oil, high-fibre, probiotic-rich, and packed with protein, antioxidants, and gut-healing goodness. Yet, it’s under-marketed compared to its benefits. Maybe it’s time we give it the spotlight it deserves,” Dr Vatsya concluded.
