Understanding food insecurity issues is in part contingent on understanding food consumption and its costs. We develop estimates of protein, lipid, and carbohydrate macronutrient consumption from household food consumption in western Kenya. We then calculate the shadow price per gram of macronutrient consumption as a share-weighted expense-consumption ratio. Using household bovine, goat, and sheep livestock health observations linked to each household, we analyze the association between livestock illness and macronutrient prices. We find that on average carbohydrates have a 75% budget share, with protein at 14% and lipids at 11%. Average macronutrient shadow prices are 0.0936 Ksh/g for carbohydrates, 0.4373 Ksh/g for protein, and 0.5938 Ksh/g for lipids. Average village-level livestock illness occurrences have significant effects on macronutrient shadow prices. Increasing average bovine illness at the village level by one additional case results in a marginal increase of the shadow prices of protein, lipids, and carbohydrates by 0.11, 0.12, and 0.03 (Ksh/g), respectively. Associated marginal impacts of sheep illness occurrence on protein, lipid, and carbohydrate shadow prices (Ksh/g) are 0.1405, 0.182, and 0.0455, respectively. This exploratory analysis provides empirical evidence that livestock illness is associated with increased macronutrient shadow prices, and hence the costs of available energy consumption. These results help guide policy instruments focused on market forces of nutrient consumption and its relationship with livestock health in undernourished areas with smallholder farming systems.

了解粮食不安全问题在一定程度上取决于对粮食消费及其成本的了解。我们对肯尼亚西部家庭食品消费中的蛋白质、脂质和碳水化合物常量营养素消耗量进行了估算。然后，我们将每克常量营养素消耗的影子价格计算为份额加权费用消耗比率。利用与每个家庭相关的家庭牛、山羊和绵羊牲畜健康观察，我们分析了牲畜疾病与常量营养素价格之间的关联。我们发现碳水化合物平均占预算份额的 75%，蛋白质占 14%，脂质占 11%。碳水化合物的平均大量营养素影子价格为 0.0936 Ksh/g，蛋白质的平均影子价格为 0.4373 Ksh/g，脂质的平均影子价格为 0.5938 Ksh/g。村级牲畜平均疾病发生率对宏量营养素影子价格有显着影响。村庄一级的平均牛疾病增加一例，会导致蛋白质、脂质和碳水化合物的影子价格分别边际增加 0.11、0.12 和 0.03 (Ksh/g)。绵羊疾病发生对蛋白质、脂质和碳水化合物影子价格 (Ksh/g) 的相关边际影响分别为 0.1405、0.182 和 0.0455。这项探索性分析提供了经验证据，表明牲畜疾病与宏量营养素影子价格的增加有关，从而与可用能源消耗的成本有关。这些结果有助于指导政策工具重点关注营养消耗的市场力量及其与小农耕作系统营养不足地区牲畜健康的关系。
