Dataset for 'Region-specific nutritious, environmentally friendly, and affordable diets in India'

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.本数据集为论文《印度区域特色营养友好、环境可持续且经济可负担的膳食方案》提供数据支撑。随附补充表S1至表S6，具体信息如下： 表S1 各邦当前人均每日营养素摄入量与推荐每日摄入量（RDA）的比值。比值大于1代表营养素摄入充足，小于1则提示存在营养素缺乏。优化膳食的所有比值均大于或等于1，故未在此表中列出。 表S2 各邦（含城镇与农村地区）当前（实测）与优化后膳食的人均每日环境足迹。超出人均每日行星边界的环境足迹将以红色标注。 表S3 各邦为实现可持续膳食所需调整的食物摄入量。针对111种食物，分别列出最优摄入量与当前摄入量的差值（单位：克·人⁻¹·天⁻¹）。公共分配系统（PDS）指政府以补贴价格向贫困群体售卖大米、小麦、食糖等物资的公共分发体系。此外，本表格还列明了19个广义食物类别的所需摄入量调整幅度。 表S4 各邦当前（实测）与优化后膳食的膳食可持续性指标值。这些指标包括：平均营养素缺乏量（MND，公式2）、平均环境比值（MER，公式3）、食品支出占比（PEF，公式4）以及与当前膳食的偏离百分比（公式5）。相关细节详见正文实验方法部分的公式2至公式5，可视化呈现参见图1。 表S5 为便于读者解读图3与补充图S5中的结果，本补充表S5通过颜色编码标注了每种食物在各营养-环境维度组合下所属的象限。例如，第一象限食物（价格与环境足迹均较低）以绿色编码；第二象限食物（价格较低但环境足迹较高）以黄色编码；第四象限食物（价格较高但环境足迹较低）以橙色编码；第三象限食物（价格与环境足迹均较高）以红色编码。通过此方式，读者可快速判断某一特定营养-环境维度组合下每种食物的可持续性水平。 表S6 从不同来源收集的25种印度作物的产量缺口（百分比）。填补这些产量缺口可确保印度当前的耕地面积（约160万平方千米）足以供养所有国民，并满足本研究确定的可持续膳食需求。
