A centuries-old food system shaped by the harsh ecology and isolation of Himachal Pradesh’s Pangi Valley has been proposed as a distinct dietary pattern with a potential to protect against non-communicable diseases (NCDs), in a study published in the Journal of Family Medicine and Primary Care

The study, led by Dr Sunil Kumar Raina, seeks to give a scientific identity to the traditional diet of the Pangwal and Bhot communities of Pangi Valley, proposing the name “Pangi Valley Diet” (PVD) for a food pattern that researchers say, shares several structural characteristics with established protective diets, such as the Mediterranean diet

Dr Raina said the study was aimed at bringing scientific attention to a traditional food system that evolved through the communities’ close relationship with the local environment. He said documenting the diet was important — not only for understanding its potential health benefits — but also because the traditional food culture was undergoing rapid change with increasing market integration

Unlike modern diets designed around nutritional prescriptions, the PVD evolved through necessity. Pangi’s high-altitude terrain, prolonged winters, heavy snowfall, short growing season and historical geographical isolation forced its communities to rely heavily on locally available grains, wild plants, livestock and traditional food-preservation methods
The researchers argue that this ecological adaptation produced a naturally nutrient-dense diet characterised by whole grains, wild edible plants, fermented foods, high-altitude dairy and very little refined or ultra-processed food

The study draws on existing ethnographic, nutritional and ecological literature rather than primary dietary or clinical data. It documents 81 traditional cuisines of the two communities, classified into categories including flatbreads, beverages, meat-based dishes, soups and curries, vegetables, fruits, pancakes, steamed foods and sweets
One defining feature of the traditional food system is its dependence on locallyewed in the study, wild plants account for around 49 per cent of the ingredients used in traditional cuisines, cultivated plants 40 per cent, purchased ingredients seven per cent and dairy products four per cent
Traditional grains form an important component of the diet. Buckwheat and barley, along with locally adapted varieties such as phullan and bres, were historically important staples. The researchers link buckwheat’s fibre, resistant starch and rutin content, and barley’s beta-glucan content, with mechanisms associated with better glycaemic control and cardiovascular health
The paper gives particular attention to Pangi’s extensive use of wild edible plants. Locally collected greens, ferns, tubers and other plants add micronutrients and a wide range of phytochemicals to the diet. Sea buckthorn (Hippophae rhamnoides), native to the Himalayan region, is highlighted for its antioxidant and other bioactive compounds
Another distinctive feature is fermentation. Foods and beverages such as chhang, churpa and fermented dairy products formed part of the traditional food system. The researchers point to the potential importance of fermentation in improving mineral bioavailability and providing beneficial microorganisms, while noting the growing evidence linking gut microbial health with metabolic regulation
Yak and chauri dairy products also occupy a prominent place in the traditional diet. The study discusses the distinctive nutritional characteristics of yak milk, including its fatty-acid profile and bioactive components, while noting that the nutritional properties of chauri products require further direct scientific characterisation
Perhaps the strongest structural feature of the PVD, researchers argue, is what it traditionally lacked: refined carbohydrates and ultra-processed foods. The traditional food system developed with minimal dependence on commercially processed products. Market integration, however, has begun changing this pattern, with wheat flour, rice, soybean and other externally
The study draws a parallel with the evolution of the Mediterranean diet as a scientific dietary model. The Mediterranean diet became a globally recognised research instrument after researchers transformed a culturally embedded regional food pattern into a measurable dietary exposure. The authors argue that the same scientific pathway can be applied to traditional diets outside Europe
To facilitate such research, the paper proposes a preliminary Pangi Valley Diet Score. Foods such as traditional whole grains, wild edible plants, high-altitude fruits, fermented foods, yak or chauri dairy and legumes would receive positive scores, while refined grains, added sugar, sugar-sweetened beverages, ultra-processed foods, commercial vegetable oils and fast foods would receive negative scores
The researchers stress that the proposed score would need to be developed and validated using population-specific dietary data and tested against health outcomes before it could be used as a clinical or epidemiological tool
The study also highlights an urgent cultural dimension to the research. The traditional Pangi food system is undergoing rapid change as the valley becomes increasingly connected to markets and outside food supplies. The authors argue that documenting the diet now could help preserve both its scientific value and the food heritage of the communities that developed it
Dr Raina’s study does not present the PVD as a clinically proven therapeutic diet. Rather, it proposes it as a scientifically testable dietary pattern whose combination of whole grains, wild plants, fermented foods, traditional dairy and minimal processed food provides a biologically plausible basis for future research into its relationship with diabetes, cardiovascular disease and other NCDs
In doing so, the study places an indigenous Himalayan food tradition on the research map and raises the possibility that Pangi’s traditional kitchen could offer more than a record of the past—it could provide a valuable model for studying healthier dietary patterns in the future
