“…The NRF9.3 model, developed by Drewnowski [ 26 ], was used to assess the nutritional quality of the product, as it seems to be the most appropriate indicator within a WEF nexus approach [ 28 ]. The NRF index is a formal scoring system that ranks foods on the basis of their nutrient content, helping consumers to identify nutritious foods and design healthier diets [ 41 ].…”

“…Within this framework, nutrient profile (NP) models have become the basis for regulating nutrition and health claims in the European Union [ 26 ]. These indicators enable characterizing food options according to their nutritional quality and have several applications including supporting consumers to make healthy food choices, as well as establishing regulations on the basis of nutrition claims [ 27 ], presenting a very useful tool for assessing nutritional aspects considering a nexus approach [ 28 ].…”

The water–energy–food (WEF) nexus has become a key concept to promote the cross-sectoral coordination toward sustainable development. In particular, understanding the interdependences of these pillars, as well as addressing a life cycle perspective, is essential when evaluating food production systems. This study explores the environmental impacts and nutritional quality of potato chips, addressing life cycle thinking and a WEF nexus approach. For this purpose, the combined application of life cycle assessment (LCA) and the Nutrient-Rich Food 9.3 (NRF9.3) index was considered to identify the main environmental hotspots and advanced opportunities. The results indicated a major contribution of the cultivation stage on water use, whereas the processing accounted for most of the impacts in energy-related indicators and eutrophication potentials. Improvement opportunities reside in the joint application of drip irrigation, allowing to achieve important water savings, as well as the use of natural gas or pellets instead of diesel, which constitute cleaner energy sources. On the other hand, a poor nutritional density of potato chips became evident from the quantification of the NRF9.3, which can be significantly improved if potatoes undergo a roasted process instead of frying.

“…The reason behind this is due to this indicator allows benchmarking a sample of dairy systems that produce the same product (i.e., raw milk). Moreover, the food security concept, one of the core elements of the WEF nexus concept, is addressed through this indicator (Fernández-Ríos et al, 2021).…”

“…In order to develop the review protocol, the Preferred Reporting Items for Systematic review and meta-analysis protocols (PRIMA-P) guideline was used as a reference [12]. For searching the publications in the field of study, this review has used Scopus as the database for the development of the review, based in the reviewing methodology presented in other publications in the literature, such as Fernández-Ríos et al [13]. In order to do a complete follow-up of all the publications registered around the analyzed topic, a first round of searching, using the keywords "energy assessment food" was carried out on 14 October 2021, as shown in Figure 1.…”

The intensity in energy consumption due to food production systems represents a major issue in a context of natural resources depletion and an increasing worldwide population. In this framework, at least a third of global food production is being lost or wasted. Moreover, about 38% of the energy embedded in total food production is being lost. Consequently, the assessment of energy consumption in food systems, and in food loss and waste valorization systems, is an increasing trend in recent years. In this line, this work presents a systematic review, selecting 74 articles from a search of 16,930 papers regarding the key words “energy assessment food”. The aim was to determine the current and historical trends in this field of research. Results pointed to a worldwide acceleration in trends since 2014, standing out in China and other Asian countries. Concerning the topics of the publications, energy consumption in the food sector is a research field which has existed since 1979. Moreover, the study of energy valorization systems using food loss and waste is an increasing trend since 2010. Additionally, publications focused on the water–energy–food nexus appeared firstly in 2014 and have grown exponentially. Moreover, life cycle assessment highlights as the most widespread methodology used.
