Potato (Solanum tuberosum) is a global crop and by far the most important non-cereal crop in the world. Therefore, it is necessary to assure its safe consumption. This is especially relevant in the case of its cultivation in abandoned mining areas, where the population tends to return to agriculture. In the present work, the objective is to evaluate the contribution to the diet of nutrients and contaminants of potato grown in soils from the Almadén area (mining district) by studying the intestinal absorption (in vitro) of the tuber, taking into account the preparation methods for its consumption.
The results of contaminant and nutrient contents show that the potato peel retains significantly more elements (mainly in the case of toxic elements) than the flesh. Furthermore, potato (peel and flesh) is a good source of iron.
It is recommended to boil potatoes with the peel in order to minimize nutrient loss and, before consumption, peeling them to eliminate possible risks due to contaminants. In addition, to minimize the risk due of mercury and to improve the levels of calcium, magnesium, potassium and sodium, it is recommended to add salt during the boiling process. © 2017 Society of Chemical Industry.
马铃薯（Solanum tuberosum）是一种全球性作物，也是目前世界上最重要的非谷类作物。因此，确保其安全食用至关重要。在废弃矿区种植马铃薯的情况下尤其如此，因为当地居民往往会重新从事农业生产。在本研究中，目标是通过研究块茎的肠道吸收（体外）情况，并考虑其食用的制备方法，评估阿尔马登地区（矿区）土壤中种植的马铃薯对饮食中营养成分和污染物的贡献。
污染物和营养成分含量的结果表明，马铃薯皮比薯肉保留了更多的元素（主要是有毒元素）。此外，马铃薯（皮和肉）是铁的良好来源。
建议带皮煮马铃薯以尽量减少营养损失，食用前再去皮以消除因污染物带来的潜在风险。此外，为尽量减少汞带来的风险并提高钙、镁、钾和钠的含量，建议在煮的过程中加盐。© 2017 化学工业协会。
