Potatoes can be an important part of a balanced diet because they are an excellent source of many nutrients, including nutrients that are commonly underconsumed (dietary fiber and potassium). Despite the existence of many positive nutrients in potatoes, the popular press has recently aligned potatoes, and particularly fried potatoes, with an unhealthy diet. This article examines the nutritional content of potatoes and how these nutrients are affected by cooking and other food-processing operations. In addition, it examines how the nutritional content of potatoes is altered by cooking methods and how fried potatoes can have wide variations in fat content depending on the cooking method. Finally, the potential of new food-processing technologies to improve the nutritional content of cooked potatoes is evaluated.
土豆可以成为均衡饮食的重要组成部分,因为它们是许多营养物质的极好来源,包括通常摄入不足的营养物质(膳食纤维和钾)。尽管土豆中存在许多有益的营养成分,但最近大众媒体将土豆(尤其是炸薯条)与不健康的饮食联系在一起。本文研究了土豆的营养成分,以及这些营养成分在烹饪和其他食品加工操作过程中的变化。此外,还研究了土豆的营养成分如何因烹饪方法而改变,以及炸薯条的脂肪含量因烹饪方法而异的原因。最后,评估了新技术在改善熟土豆的营养成分方面的潜力。
