Dataset for 'Region-specific nutritious, environmentally friendly, and affordable diets in India'
Description
This dataset provides the data for the manuscript titled 'Region-specific nutritious, environmentally friendly, and affordable diets in India'. Following Tables S1-S6 are provided: Table S1. Ratio of current daily per capita nutrient intake and its recommended daily allowance (RDA) for each state. A ratio higher than one indicates that nutrient intake is sufficient and below one indicates nutrient deficiency. For optimized diet, all ratios are equal to or above one and hence not shown. Table S2. Environmental footprints of daily per capita curent (obs) and optimized (opt) diets of each state (both urban and rural areas). Footprints exceeding daily per capita planetary boundaries are marked in red. Table S3. Required changes in the intake of food items to achieve sustainable diet in each state. Difference between optimum and current intake amounts (in grams per capita per day) are shown for each of the 111 food items. PDS is public distribution system under which an item (rice, wheat, sugar) is sold by government at subsidized rates to poor. Required intake changes in 19 broad food groups are also shown. Table S4. Values of dietary sustainability metrics per state for current (obs) and optimized (opt) diets. The metrics are mean nutrient deficiency (MND, Eq. 2), mean environmental ratio (MER, Eq. 3), % expenditure on food (PEF, Eq. 4) and % departure from current diets (Eq. 5). See equations 2-5 in Experimental procedure section in the main text for details and Figure 1 for visual representation. Table S5. To aid the readers in making inferences from results presented in Figure 3 and Figure S5, we have now added Supplementary Table S5 showing in which quadrant does each of the food item lie for each nutrient-environment domain combination through a color code. For example, the first quadrant food items (which are low on price and environmental footprint) are coded green. The second quadrant food items (low in price but high in environmental footprint) are coded in yellow. The fourth quadrant food items (high in price but low in environmental footprint) are coded in orange. Finally, the third quadrant food items (high in price and high in environmental footprint) are coded in red. This way the reader can easily identify how sustainable is each food item for a particular nutrient-environmental domain combination. Table S6. Yield gaps (in %) of 25 Indian crops gathered from different sources. Filling these gaps would ensure the current cropland extent in India (~1.6 million km2) is enough to feed all citizens with the sustainable diet identified in this study.
