The EAT-Lancet Commission proposed a dietary framework aimed at reducing the ecological footprint of diets worldwide, but research on adherence to this diet in Latin America is limited. This study aimed to describe the adherence of urban diets in 8 Latin American countries to the EAT-Lancet diet and its association with micronutrient intake inadequacy. This cross-sectional study analyzed baseline data from the Latin American Study of Nutrition and Health, involving 6835 participants from Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Peru, and Venezuela. Data collection included two 24-hour recalls, alongside socio-demographic variables. Usual dietary intake was estimated via the Multiple Source Method and micronutrient inadequacy was evaluated with the Nutrient Adequacy Ratio. The Planetary Health Diet Index (PHDI; ranged between 0 and 150) assessed adherence to the EAT-Lancet diet. Adherence was low (29.7%) across the region, with an average PHDI score of 44.6 ± 9.2 points. Costa Rica had the highest adherence (32.9%), while Argentina had the lowest (25.8%). Older participants, those with overweight/obesity, and with higher socioeconomic status, education, and physical activity had higher adherence. Higher adherence was associated with increased inadequacy risks for cobalamin, vitamin D, and calcium, but decreased risks for pyridoxine, folate, vitamin C, magnesium, and zinc. The study suggests that low adherence may stem from a disconnect between culturally ingrained dietary habits and the EAT-Lancet recommendations, which are primarily informed by nutritional epidemiology and environmental considerations. Recognizing and honoring diverse food cultures is crucial for promoting dietary practices that support human health and environmental sustainability.
“柳叶刀 - 饮食委员会”提出了一个饮食框架，旨在减少全球饮食的生态足迹，但拉丁美洲关于遵循这种饮食的研究有限。本研究旨在描述拉丁美洲8个国家城市饮食对“柳叶刀 - 饮食”的遵循情况及其与微量营养素摄入不足的关联。这项横断面研究分析了拉丁美洲营养与健康研究的基线数据，涉及来自阿根廷、巴西、智利、哥伦比亚、哥斯达黎加、厄瓜多尔、秘鲁和委内瑞拉的6835名参与者。数据收集包括两次24小时饮食回顾，以及社会人口统计学变量。通过多源法估计日常饮食摄入量，并使用营养素充足率评估微量营养素不足情况。行星健康饮食指数（PHDI；范围在0至150之间）评估对“柳叶刀 - 饮食”的遵循情况。该地区的遵循率较低（29.7%），平均PHDI得分为44.6±9.2分。哥斯达黎加的遵循率最高（32.9%），而阿根廷最低（25.8%）。年龄较大的参与者、超重/肥胖者以及社会经济地位较高、受教育程度较高和身体活动较多的人遵循率较高。较高的遵循率与钴胺素、维生素D和钙摄入不足风险增加相关，但与吡哆醇、叶酸、维生素C、镁和锌摄入不足风险降低相关。该研究表明，低遵循率可能源于根深蒂固的文化饮食习惯与主要基于营养流行病学和环境考量的“柳叶刀 - 饮食”建议之间的脱节。认识并尊重多样的饮食文化对于推广支持人类健康和环境可持续性的饮食习惯至关重要。
