New Insights into Fermented Foods
A recent study by the Institute of Advanced Study in Science and Technology (IASST), Guwahati, an autonomous institute under the Department of Science & Technology (DST), has revealed that fermented foods can play a vital role in personalising nutrition for India’s diverse population.
Why Fermented Foods Matter
Researchers found that fermented foods such as yogurt, idli, miso, natto, kimchi, and fermented fish are rich in bioactive peptides (BAPs) — short protein fragments of 2–20 amino acids. These BAPs interact with biomolecules through electrostatic forces and hydrogen bonding to exert powerful health benefits.
Health Benefits Identified
- Regulation of blood pressure and blood sugar
- Strengthened immunity
- Reduced inflammation
- Antimicrobial, antioxidant, and immune-modulatory effects
Precision Nutrition for India
The study highlights that the effectiveness of BAPs varies across populations due to factors like genetic polymorphisms, gut microbiota, dietary habits, and health conditions. For example, gene variants in ACE or IL-6 can influence individual responses.
Global Relevance & Public Health Integration
Published in the journal Food Chemistry (2025), the research emphasizes the importance of precision nutrition and recommends incorporating fermented foods into public health programs. It also calls for omics-based research and innovations in rural food systems to position India as a global leader in personalised nutrition.
India’s Path Ahead
By integrating traditional knowledge with cutting-edge biotechnology, India can use fermented foods not only to improve public health but also to create a sustainable model for Atmanirbhar Bharat in nutrition science.
