A historical exploration of Indian diets and a possible link to insulin resistance syndrome

The data presented shows a gradual shift over the centuries from the Pastoral Age diet of large quantities of high-fibre carbohydrates, small amounts of digestible carbohydrates, moderate fats, moderate proteins, to an increasing and frequent intake of high-fibre carbohydrates associated with significant drop in protein and fat consumption between 1775 and 1947. From 1947 onwards there has been an increase in the frequency of intake and quantities of low-fibre and refined carbohydrates, and fats with protein intake improving only marginally.
