The dietary habits of people directly impact their health conditions. Especially in elder populations (in 2017, 6.7% of the world's population was over 65 years of age), these habits could lead to important-nutrient losses that could seriously affect their cognitive and functional state. Recently, a great research effort has been devoted to using different technologies and proposing different techniques for monitoring food-intake. Nevertheless, these techniques are usually generic but make use of the most innovative technologies and methodologies to obtain the best possible monitoring results. However, a large percentage of elderly people live in depopulated rural areas (in Spain, 28.1% of the elderly population lives in this type of area) with a fragile cultural and socioeconomic context. The use of these techniques in these environments is crucial to improving this group's quality of life (and even reducing their healthcare expenses). At the same time, it is especially challenging since they have very specific and strict requirements regarding the use and application of technology. In this Systematic Literature Review (SLR), we analyze the most important proposed technologies and techniques in order to identify whether they can be applied in this context and if they can be used to improve the quality of life of this fragile collective. In this SLR, we have analyzed 326 papers. From those, 29 proposals have been completely analyzed, taking into account the characteristics and requirements of this population.
人们的饮食习惯直接影响他们的健康状况。特别是在老年人群体中（2017 年，全球 6.7%的人口年龄在 65 岁以上），这些习惯可能导致重要营养物质的流失，严重影响他们的认知和功能状态。最近，人们投入了大量的研究努力，使用不同的技术并提出了不同的技术来监测食物摄入。然而，这些技术通常是通用的，但利用了最创新的技术和方法来获得最佳的监测结果。然而，很大一部分老年人生活在人口减少的农村地区（在西班牙，28.1%的老年人口居住在这种类型的地区），文化和社会经济背景脆弱。在这些环境中使用这些技术对于提高这一群体的生活质量（甚至降低他们的医疗保健费用）至关重要。同时，这也极具挑战性，因为他们对技术的使用和应用有非常具体和严格的要求。在本次系统文献回顾（SLR）中，我们分析了最重要的提议技术和技术，以确定它们是否可以应用于这种情况，以及它们是否可以用于改善这一脆弱群体的生活质量。在本次 SLR 中，我们分析了 326 篇论文。其中，考虑到这一人群的特点和需求，我们对 29 项提议进行了全面分析。
