国际研究界日益认识到生物多样性在提高和维持营养安全方面的潜力。然而，迄今为止，评估生物多样性实际上如何对人类饮食做出贡献的饮食评估研究几乎没有。这项研究测量了野生食用植物（WEP）的贡献，饮食质量的高生物多样性背景下的刚果。通过对363名城市妇女和129名农村妇女进行2次24小时多次膳食回忆，估计了习惯性膳食摄入量。所有的WEP收集在以前的民族植物学调查和鉴定，并存放在比利时国家植物园（BR）。结果表明，在一个生物多样性高、粮食安全不稳定的地区，水和植物提取物的消费量不足以提高营养安全或膳食充足性。在整个调查村样本中，美味小树蛙的能量摄入贡献率最高，占总能量摄入的4.8%。考虑到该区域现有的和土著居民所知的许多水和电产品的营养成分，提高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的营养成分的进一步研究将允许将其纳入该区域的适当饮食指南，并为驯化最有趣的WEP铺平道路。
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.
