To underline the importance of protein quality in plant-based diets, we estimated the protein quality of different exclusively plant-protein-based day menus that are based on the "planetary health diet" developed by the EAT-Lancet Commission. PDCAAS and DIAAS were used to estimate the protein quality (PQ) and fulfilling of the amino acid recommendation for adults in vegan daily menus based on the planetary health diet: 2 days with only low-quality (LQ) protein sources and 2 days with low + high-quality (HQ) protein sources. The protein quality of Day 1LQ (DIAAS 76, PDCAAS 88) was increased by the addition of high-quality protein sources (HQPS): Day 1HQ (DIAAS 94, PDCAAS 98). Day 2LQ had a low PQ (DIAAS 71, PDCAAS 74), but when HQPS were used (Day 2HQ), the PQ increased (DIAAS 83, PDCAAS 88). Scenarios (day 1HQ, day 1LQ, and day 2 HQ) were classified as of good PQ. However, day 1LQ had a low protein quality. Consuming HQPS in a vegan diet can help to fulfil the recommendation of essential amino acids. This work served to understand and apply methods to estimate protein quality that can be applied to optimize protein mixtures to fulfil amino acid requirements in the future.
为了强调植物性饮食中蛋白质质量的重要性，我们评估了基于 EAT-柳叶刀委员会开发的“行星健康饮食”的不同纯植物蛋白为主的日菜单的蛋白质质量。我们使用 PDCAAS 和 DIAAS 来评估基于行星健康饮食的素食日常菜单中成年人的蛋白质质量（PQ）和氨基酸推荐的满足情况：2 天只使用低质量（LQ）蛋白质源，2 天使用低+高质量（HQ）蛋白质源。第 1 天 LQ（DIAAS 76，PDCAAS 88）的蛋白质质量通过添加高质量蛋白质源（HQPS）得到提高：第 1 天 HQ（DIAAS 94，PDCAAS 98）。第 2 天 LQ 的 PQ 较低（DIAAS 71，PDCAAS 74），但当使用 HQPS 时（第 2 天 HQ），PQ 增加（DIAAS 83，PDCAAS 88）。方案（第 1 天 HQ、第 1 天 LQ 和第 2 天 HQ）被归类为具有良好 PQ。然而，第 1 天 LQ 的蛋白质质量较低。在素食饮食中摄入 HQPS 可以帮助满足必需氨基酸的推荐量。这项工作旨在了解和应用估计蛋白质质量的方法，以便将来优化蛋白质混合物以满足氨基酸需求。
