The objective of this study is to identify the availability of Nutrient Profiling (NP) models worldwide and discuss their application. This scoping review is based on the Preferred Reporting Items for Systematic Review and Meta-Analyses Extension for the Scoping Review (PRISMA-ScR) and the Arksey and O’Malley framework. Articles related to NP among adults published from 2012 to 2022, written in English, were retrieved from the Web of Science, Science Direct, Scopus, and Pubmed databases. Mendeley software was used for database acquisition and MS Excel for the syntesis process. Only 17 articles out of 2,019 article titles identified met the inclusion criteria for the review. This review discovers that the applications of NP in nutrition policies include food labelling, Front-Of-Pack (FOP), and regulations on food marketing, health, and nutrition. Fibre is the nutrient that needs to be included in the NP application compared to saturated fats, fatty acids, sodium, and total sugar. This scoping review demonstrates the scientific basis of the NP model’s development in public health policy, leading to advocacy and the recommendation of healthy diets.

The issue of food waste has garnered much attention globally due to its adverse impacts on the economy, food security, natural resources, the environment, and human health. Despite this, the academic literature lacks systematic, historical, and synthesising investigations on healthcare food waste. This bibliometrics analysis study aims to summarise the growing trends of food waste publications and highlight common and potential research topics of food waste in healthcare settings. The Scopus database analysed 193 journal articles published between 1952 and 2022. We identified several common and potential research topics for future research in the area, including food waste and malnutrition, related intervention strategies, the impact of healthcare food service systems on food waste, and their economic and environmental impact. Healthcare food waste research in developing nations is still limited. Thus, it is recommended that policymakers support its development as one of the steps to encounter food waste.
