FERMENTED FOOD & PERSONALISED NUTRITION IN INDIA
Why in News?
- A recent study by the Institute of Advanced Study in Science and Technology (IASST), Guwahati, under the Department of Science & Technology (DST), has highlighted that bioactive peptides in traditional fermented foods have population-specific health effects.
- And it could be used to develop personalized nutrition strategies tailored to India’s genetically and culturally diverse population.
WHAT ARE BIO ACTIVE PEPTIDES?
- Short chains of amino acids (2–20 amino acids) produced during the fermentation process in foods.
- Found in fermented foods like yogurt, idli, kimchi, miso, natto, and fermented fish.
- They interact with human cells through:
- Electrostatic forces
- Hydrogen bonding
- Hydrophobic interactions
HEALTH BENEFITS OF BAPs
- Antimicrobial: Helps fight harmful bacteria
- Antihypertensive: Regulates blood pressure
- Antioxidant: Reduces oxidative stress
- Immunomodulatory: Balances immune responses
- Anti-inflammatory: Helps reduce chronic inflammation
- May support cardiac health, metabolic balance, and gut microbiome diversity
PERSONALISED NUTRITION FOR INDIA’S DIVERSITY
- Effects of BAPs vary across individuals due to:
- Genetic polymorphisms (e.g. ACE, IL-6 genes)
- Gut microbiota composition
- Cultural dietary patterns
- Pre-existing health conditions
This opens the door for precision nutrition — dietary interventions tailored to individual biology and ethnicity.
SCIENTIFIC & POLICY IMPLICATIONS
1. R&D and Innovation
- Emphasizes omics-based research (genomics, proteomics, metabolomics).
- Highlights the need to improve fermentation techniques, peptide stability, and interaction mapping with gut microbiota.
2. Public Health Integration
- Suggests incorporating fermented foods into national nutrition programs, especially in rural and tribal areas.
- Supports low-cost, culturally acceptable nutrition interventions.
3. Global Leadership Potential
- India’s traditional food diversity positions it as a potential leader in global personalized nutrition
