The potential of biodiversity to increase and sustain nutrition security is increasingly recognized by the international research community. To date however, dietary assessment studies that have assessed how biodiversity actually contributes to human diets are virtually absent. This study measured the contribution of wild edible plants (WEP) to the dietary quality in the high biodiverse context of DR Congo. The habitual dietary intake was estimated from 2 multiple-pass 24 h dietary recalls for 363 urban and 129 rural women. All WEP were collected during previous ethnobotanical investigations and identified and deposited in the National Botanical Garden of Belgium (BR). Results showed that in a high biodiverse region with precarious food security, WEP are insufficiently consumed to increase nutrition security or dietary adequacy. The highest contribution came from Dacryodes edulis in the village sample contributing 4.8% of total energy intake. Considering the nutrient composition of the many WEP available in the region and known by the indigenous populations, the potential to increase nutrition security is vast. Additional research regarding the dietary contribution of agricultural biodiversity and the nutrient composition of WEP would allow to integrate them into appropriate dietary guidelines for the region and pave the way to domesticate the most interesting WEP.
生物多样性在提高和维持营养安全方面的潜力越来越受到国际研究界的认可。然而，迄今为止，实际上还没有评估生物多样性如何真正有助于人类饮食的饮食评估研究。本研究在刚果民主共和国生物多样性高的背景下，测量了野生食用植物 (WEP) 对饮食质量的贡献。通过对 363 名城市和 129 名农村妇女进行 2 次多次 24 小时饮食回忆，估计了习惯性饮食摄入量。所有 WEP 都是在之前的民族植物学调查中收集的，并在比利时国家植物园 (BR) 进行了鉴定和保存。结果表明，在一个生物多样性高、粮食安全不稳定的地区，WEP 的摄入量不足以提高营养安全或饮食充足度。在村庄样本中，来自 Dacryodes edulis 的 WEP 的贡献最高，占总能量摄入的 4.8%。考虑到该地区可获得的许多 WEP 的营养成分以及土着居民所熟知的成分，增加营养安全的潜力是巨大的。关于农业生物多样性的饮食贡献和 WEP 的营养成分的额外研究，将有助于将它们纳入该地区的适当饮食指南，并为驯化最有趣的 WEP 铺平道路。
