Fruit is a key component of a healthy diet. However, it is still not clear whether some classes of fruit may be more beneficial than others and whether all individuals whatever their age, gender, health status, genotype, or gut microbiota composition respond in the same way to fruit consumption. Such questions require further observational and intervention studies in which the intake of a specific fruit can be precisely assessed at the population and individual levels. Within the Food Biomarker Alliance Project (FoodBAll Project) under the Joint Programming Initiative "A Healthy Diet for a Healthy Life", an ambitious action was undertaken aiming at reviewing existent literature in a systematic way to identify validated and promising biomarkers of intake for all major food groups, including fruits. This paper belongs to a series of reviews following the same BFIRev protocol and is focusing on biomarkers of pome and stone fruit intake. Selected candidate biomarkers extracted from the literature search went through a validation process specifically developed for food intake biomarkers.

苹果，梨和核果的食物摄入生物标志物。

水果是健康饮食的关键组成部分。但是，尚不清楚某些种类的水果是否比其他种类的水果更有益，以及所有年龄，性别，健康状况，基因型或肠道菌群组成的个体是否对食用水果的反应相同。这些问题需要进一步的观察和干预研究，其中可以在人群和个体水平上精确评估特定水果的摄入量。在“健康饮食，健康生活”联合计划倡议下的食品生物标志物联盟项目（FoodBAll项目）中，采取了一项雄心勃勃的行动，旨在以系统的方式审查现有文献，以鉴定所有主要摄入量的有效和有前途的生物标志物食物组，包括水果。本文属于遵循相同BFIRev协议的一系列评论，并且重点研究了石榴和核果摄入量的生物标记。从文献检索中选择的候选生物标志物经过了专门为食物摄入生物标志物开发的验证过程。
