A critical nutritional gap is leaving roughly one in five pregnant and lactating women in Northeast India vulnerable to severe health complications, according to a new government study. Researchers have identified a widespread deficiency of Vitamin B1, too known as thiamine, in the Barak Valley region, describing the situation as a silent but preventable public health emergency.
The survey, conducted by the ICMR–National Institute of Nutrition (ICMR-NIN), represents one of the largest community-based assessments of thiamine levels ever carried out in India. By screening 1,083 women across 120 villages, the study found that 20.6 per cent of the participants were deficient in the essential vitamin, meaning their cellular functions were compromised due to a lack of necessary nutrients.
As a physician, I recognize thiamine as one of the most fundamental tools the human body uses to convert food into energy. When these levels drop, the impact is systemic: the heart can weaken and the nervous system may begin to fail. In the most severe cases, the deficiency leads to beriberi, a disease that was once common across Asia but was widely believed to have been eradicated in India.
The findings suggest that the recurrence of this deficiency is not merely a matter of food scarcity, but is deeply tied to dietary habits and food processing practices common in the region.
The ‘Rice Trap’: How Processing Fuels Deficiency
The study highlighted a stark correlation between the primary staple of the region—polished white rice—and the prevalence of deficiency. Over 96 per cent of the women surveyed consumed polished white rice as their main daily food source. Unlike brown or unpolished rice, the polishing process removes the husk and bran, where the majority of thiamine is stored.
Beyond the processing itself, the researchers identified two specific domestic habits that further depleted nutrient levels:
- Long-term Storage: Rice stored for extended periods loses a significant portion of its remaining thiamine. The study found that women eating stored rice were approximately three times more likely to be deficient than those consuming fresher supplies.
- Excessive Washing: A widespread regional habit of washing rice two or more times before cooking was also linked to higher deficiency rates. Given that thiamine is a water-soluble vitamin, each rinse physically washes the nutrient away before it ever reaches the pot.
Conversely, the research found a protective effect in traditional diets. Women who regularly consumed fermented fish or fish paste—staples of the local culture—showed lower rates of deficiency, suggesting that these traditional preservation methods may naturally safeguard against B1 loss.
Comparing Dietary Risk Factors in Barak Valley
| Dietary Habit | Effect on Vitamin B1 | Risk Level |
|---|---|---|
| Polished White Rice | Removes nutrient-rich bran | High |
| Long-term Rice Storage | Natural degradation of vitamin | Very High |
| Multiple Rice Rinses | Washes away water-soluble B1 | High |
| Fermented Fish/Paste | Provides natural protection | Protective |
The Fatal Link to Infant Mortality
The most urgent concern raised by the ICMR-NIN researchers is the direct impact on newborns. Thiamine deficiency in a breastfeeding mother leads to a corresponding deficiency in her breast milk. For a newborn who relies exclusively on this milk for survival, the lack of B1 can be life-threatening.
The study points to a devastating trend in the Barak Valley, where hospital records and outbreak investigations suggest that approximately one in five infant deaths in the region is attributed to suspected beriberi. Because an infant cannot regulate its own nutrient intake, it is entirely dependent on the mother’s nutritional status.
“A baby cannot protect itself from this. It depends completely on its mother’s nutrition. Every mother who goes into pregnancy or breastfeeding with enough thiamine is a baby protected from a death that should never happen,” the research stated.
A Call for Strategy Shifts
The study concludes that this crisis is entirely avoidable. Dr. Mahesh Kumar Mummadi, a medical scientist in the Clinical Epidemiology Division at ICMR-NIN and the lead investigator, emphasized that the medical community already possesses the tools to eliminate these deficiencies.
The primary hurdle is policy. Dr. Mummadi argued that thiamine should be explicitly integrated into India’s broader maternal nutrition strategy rather than being dismissed as a relic of the past. Addressing the gap would likely involve a combination of dietary education regarding rice preparation and targeted supplementation for high-risk populations in the Northeast.
For those seeking more information on maternal nutrition and vitamin requirements, the World Health Organization (WHO) provides global guidelines on prenatal care and essential micronutrients.

The next step for health officials will be determining how to integrate these findings into the national maternal health framework, with a focus on updating nutritional guidelines for the Northeast region to prevent further infant mortality.
