ICMR Study Links Carb-Heavy Indian Diets to Higher Diabetes Risk

Researchers report that swapping 5% of daily calories from carbohydrates for plant or dairy protein is associated with lower odds of diabetes and prediabetes.

Overview

  • The Nature Medicine paper analyzes nationally representative data from 121,077 adults across 36 states and union territories in the ICMR-INDIAB survey.
  • Indians obtain about 62% of calories from carbohydrates, largely from white rice, milled grains, and added sugar, while protein averages only 12% of energy.
  • Modelled substitution suggests replacing a small share of carbohydrate calories with plant or dairy proteins lowers metabolic risk, whereas swapping with red meat protein or fats does not show the same benefit.
  • Average total fat meets national guidelines, but saturated fat exceeds the <7% energy threshold in all but four states, and at least 21 states surpass the <5% energy recommendation for added sugar.
  • Authors urge policy changes on food subsidies and public messaging to promote pulses, legumes and dairy protein and to cut reliance on refined cereals and saturated fats.
