Driven by perceived health and environmental benefits, initiatives to remove red meat from recommended eating patterns are increasingly being implemented in United States institutions, including schools and hospitals. While these efforts aim to address important issues, they may inadvertently lead to unintended consequences, particularly regarding essential nutrient intake for certain populations. This perspective considers the nutritional value of red meat, examines its potential health benefits, and highlights nutritional risks when intake is reduced or eliminated. Red meat is a nutrient-dense food that provides highly bioavailable protein and several essential micronutrients often lacking in the diet, including iron, zinc, and vitamin B. These nutrients can be limited or absent in many plant-source foods as well as in some animal-source foods. Red meat's micronutrient profile is especially valuable for young children and women of reproductive age, including pregnant women. In addition, the protein density of red meat is beneficial for individuals managing obesity and older adults at risk of sarcopenia. Many epidemiological studies suggest potential associations between excessive red meat consumption and increased risk of certain chronic diseases, but this evidence does not conclusively implicate red meat in the development or progression of chronic disease. The nutritional and health implications of reducing red meat consumption must be balanced against the low certainty of evidence used to discourage red meat intake when making dietary recommendations.
在美国的一些机构,包括学校和医院,受人们所认为的健康和环境益处的驱使,将红肉从推荐饮食模式中去除的举措正在越来越多地实施。虽然这些努力旨在解决重要问题,但它们可能会无意中导致意想不到的后果,特别是在某些人群的必需营养素摄入方面。本文观点考虑了红肉的营养价值,研究了其潜在的健康益处,并强调了减少或消除红肉摄入时的营养风险。红肉是一种营养密集型食物,能提供生物利用率高的蛋白质以及几种饮食中常常缺乏的必需微量营养素,包括铁、锌和维生素B。这些营养素在许多植物源食物以及一些动物源食物中可能有限或缺乏。红肉的微量营养素构成对幼儿和育龄妇女(包括孕妇)尤其有价值。此外,红肉的蛋白质密度对控制肥胖的人和有肌肉减少症风险的老年人有益。许多流行病学研究表明,过量食用红肉与某些慢性病风险增加之间可能存在关联,但这一证据并未确凿地表明红肉与慢性病的发生或发展有关。在提出饮食建议时,减少红肉消费对营养和健康的影响必须与用于劝阻红肉摄入的证据的低确定性相权衡。
