In January 2019, the EAT-Lancet Commission defined a universal reference diet to promote human and environmental health. However, in doing so, the potential consequences for brain health were not considered. Whilst plant-based diets are generally associated with better cognitive and affective outcomes, those that severely limit animal products are not. Therefore, the potential ramifications of the EAT-Lancet diet on cognition, mood, and heart rate variability were considered ( = 328). Adherence to the Alternative Healthy Eating Index (AHEI) was associated with having a better mood, focused attention, working and episodic memory, and higher heart rate variability. However, when the EAT-Lancet diet was considered, the effects were either smaller or not significant. Cluster analysis identified a dietary style characterised by a strong adherence to the EAT-Lancet recommendation to limit meat intake, representing a sixth of the present sample. This group had a lower Mean Adequacy Ratio (MAR); did not meet the Recommended Nutrient Intake (RNI) for a range of nutrients including protein, selenium, zinc, iron, and folate; and reported a poorer mood. These data highlight the potential unintended consequences of the EAT-Lancet recommendations for nutritional adequacy and affective health in some individuals. There is a need to better optimise the EAT-Lancet diet to support brain health. As we move towards more sustainable diets, these findings emphasise the need to consider how such diets might affect the brain.
2019 年 1 月，EAT-柳叶刀委员会定义了一种通用参考饮食，以促进人类和环境健康。然而，在这样做的过程中，并没有考虑到对大脑健康的潜在影响。虽然植物性饮食通常与更好的认知和情感结果相关，但那些严重限制动物产品的饮食则不然。因此，考虑了 EAT-柳叶刀饮食对认知、情绪和心率变异性的潜在影响（n=328）。对替代健康饮食指数（AHEI）的依从性与更好的情绪、注意力集中、工作和情景记忆以及更高的心率变异性相关。然而，当考虑 EAT-柳叶刀饮食时，其影响要么较小，要么不显著。聚类分析确定了一种饮食方式，其特点是强烈遵循 EAT-柳叶刀的建议，限制肉类摄入，占当前样本的六分之一。这组人的平均充足率（MAR）较低；未达到推荐的营养素摄入量（RNI），包括蛋白质、硒、锌、铁和叶酸在内的多种营养素；情绪较差。这些数据突出了 EAT-柳叶刀建议对某些人营养充足和情感健康的潜在意外后果。需要更好地优化 EAT-柳叶刀饮食以支持大脑健康。随着我们朝着更可持续的饮食发展，这些发现强调了需要考虑这些饮食如何影响大脑的问题。
