食用多种食物的建议是国际公认的健康饮食建议。饮食多样化的重要性基于多项研究，这些研究表明多样化的饮食可以带来积极的健康结果。然而，健康食品多样性的定义和衡量在文献中经常受到批评。营养研究通常使用计数指数来量化食物多样性。由于这些措施有相当大的缺点，一些营养学家呼吁对食物多样性进行精确的定义和测量。这项研究旨在开发一种新的健康食品多样性指标。该指数基于主要应用于经济和生态研究的分布测量。它考虑了健康食品多样性的三个重要方面：消费食品的数量、分布和健康价值。我们利用能量调整后与饮食质量指标的相关性验证了新指数。与选定的传统多样性指数的比较表明，新指标更恰当地反映了健康食品的多样性。
The recommendation to eat diverse types of foodstuffs is an internationally accepted recommendation for a healthy diet. The importance of dietary variety is based on several studies that have shown that diverse diets are accompanied by positive health outcomes. However, the definition and measurement of healthy food diversity are often criticized in the literature. Nutritional studies generally use count indices to quantify food diversity. As these measures have considerable disadvantages, several nutritionists have called for a precise definition and measurement of food diversity. This study aimed to develop a new healthy food diversity indicator. This index is based on a distribution measure mainly applied in economic and ecological studies. It considers 3 aspects important for healthy food diversity: number, distribution, and health value of consumed foods. We have validated the new index using energy-adjusted correlations with diet quality indicators. A comparison with selected traditional diversity indices revealed that the new indicator more appropriately reflected healthy food diversity.
