Along the Alps, the Alpine diet is considered to be one of the most common nutritional models. Next to traditional animal-based products, spontaneous plants of the territory are collected and eaten.
The aim of this study is to evaluate the nutritional features of selected autochthonous plants of the territory and the typical recipe of green gnocchi.
The analyses of proximate composition, carotenoid, total phenol, and mineral contents in raw and cooked plant samples and the chemical composition and in vitro starch digestibility in green and control gnocchi were performed.
Except for all the wild plants contained high levels of carotenoids (15-20 mg/100 g FW), mainly as xanthophylls. showed the highest levels of total phenols (554 mg GAE/100 g FW), and can be considered to be a good dietary source of iron, calcium, and magnesium (4.9, 410, and 72 mg/100 g FW). Cooking significantly decreased the potassium and magnesium contents in all wild species, and total phenols and carotenoids in , and ( < 0.05). The slowly digestible fraction of starch (%SDS/available starch), which is inversely correlated to insulin demand, was significantly increased in green gnocchi compared to matched control gnocchi ( < 0.05).
Traditional consumption of spontaneous plants in the Alpine regions might increase the dietary intakes of several bioactive substances and contribute to cover the nutritional needs of micronutrients.
阿尔卑斯山脉地区的饮食被认为是最常见的营养模式之一。除了传统的动物源性产品外，还会采集和食用当地的野生植物。
本研究旨在评估当地选定的乡土植物和典型的绿色团子的营养特征。
对原料和烹饪后的植物样品的常规成分、类胡萝卜素、总酚、矿物质含量以及绿色和对照团子的化学组成和体外淀粉消化率进行了分析。
除了所有野生植物都含有高含量的类胡萝卜素（15-20mg/100gFW），主要为叶黄素外，还发现 中总酚含量最高（554mgGAE/100gFW），可作为铁、钙和镁的良好膳食来源（4.9、410 和 72mg/100gFW）。烹饪显著降低了所有野生植物中的钾和镁含量，以及 和 中的总酚和类胡萝卜素（<0.05）。与匹配的对照团子相比，绿色团子中淀粉的缓慢消化部分（% SDS/可利用淀粉）显著增加，而淀粉的缓慢消化部分与胰岛素需求呈负相关（<0.05）。
阿尔卑斯地区传统食用野生植物可能会增加几种生物活性物质的膳食摄入量，并有助于满足微量元素的营养需求。
