The transition of food consumption towards sustainable patterns based on environmental, economic and nutritional aspects

É máis urxente que nunca acadar un sistema alimentario sostible que sexa respectuoso co medio ambiente, que ofreza seguridade e calidade alimentaria a toda a poboación mundial e, ao mesmo tempo, sexa social e economicamente aceptable. Para iso, os cambios nos patróns alimentarios actuais son unha das ferramentas máis poderosas e eficaces. A adhesión ás dietas tradicionais, baseadas principalmente no consumo de produtos de orixe vexetal e o consumo limitado de produtos de orixe animal e ultra-procesados, considérase como a pedra angular para acadar este obxectivo. Así, esta tese ten como principal finalidade analizar diferentes patróns de consumo de alimentos desde o punto de vista ambiental, nutricional e socioeconómico, e propoñer as medidas axeitadas para lograr patróns dietéticos más sostibles. Ademais, o proceso de produción de alimentos tamén se analiza en profundidade mediante a análise do ciclo de vida de produtos agro-alimentarios relevantes

Carbon footprint and nutritional quality of different human dietary choices

Apart from industrial activities, our eating habits also have a significant environmental cost associated with crop cultivation, manufacturing processes, packaging, refrigeration, transport cooking and waste management. In a context of growing social awareness of the role of different dietary choices in the environment, the review of different alternatives on the road to a healthy and sustainable diet should integrate relevant information on the nutritional quality of different eating habits. Since dietary choices have an effect on environmental sustainability and human health, a literature review on different dietary choices has been conducted to determine the differences in carbon footprint and nutritional quality identifying the main hotspots trying to give advice towards the identification of sustainable diets. After applying a set of criteria for reference selection, 21 peer-reviewed studies have been analysed in detail, allowing the comparison of 66 dietary scenarios. We identified that the so-called Mediterranean and Atlantic diets present high nutritional scores and low carbon footprints. On the contrary, the dietary choices identified in northern and Western Europe, as well as in the United States, have the highest carbon footprints, highlighting the contribution of dairy products as a basic source of high-quality nutrients and protein. Broadly speaking, dietary choices rich in vegetables (e.g., vegan, vegetarian as well as Indian and Peruvian) have a better environmental profile than those rich in meat (mainly ruminant meat). In line with these findings, the shift in meat consumption habits from beef and veal to chicken, pork and poultry, the introduction of alternative foods to animal protein (e.g. quinoa) and the consumption of olive oil as a major source of vegetable oil may be compatible with a healthier and more environmentally friendly diet. However, the complete elimination of meat and dairy products from the daily diet may not be feasible in case the supply of some micronutrients (e.g., calcium and vitamin D) is not guaranteed. Limitations were identified in the consulted studies related to the consideration of the different system boundaries, as well as underlying uncertainties related to data sources. Therefore, efforts should be made to develop consistent and agreed-upon methods for estimating both the carbon footprint and nutritional quality scoresThis research has been supported by a project granted by Xunta de Galicia (project ref.

Linking environmental sustainability and nutritional quality of the Atlantic diet recommendations and real consumption habits in Galicia (NW Spain)

Today's society is increasingly aware of food consumption patterns. Under the perspective that real consumption trends are often not in line with healthy recommendations, this research focuses on the study of the environmental and nutritional sustainability of two types of food consumption habits present in the northern Atlantic area of Spain (Galicia). The main objective is, therefore to detect the existing deviations between the current Galician diet (GD) and the traditional and increasingly relevant Recommended Atlantic Diet (RAD), allowing verifying whether current consumption patterns ensure an optimal and sustainable nutritional profile. In this sense, the carbon footprint from a Life Cycle Assessment perspective has been estimated as environmental indicator of both dietary patterns and, the nutritional quality has been determined by the Nutrient Rich Diet 9.3 index and the Health gain score. The carbon footprint of both dietary models is moderately high compared to recommended diets such as the Mediterranean one. Comparing the two scenarios, the associated greenhouse gas emissions are about 15% higher for GD than for RAD, mainly due to the higher intake of beef and dairy products. On the other hand, nutritional quality is comparatively higher for RAD than for GD, associated with higher consumption of vegetables and fruits. An additional objective of this work has been to consider a sensitivity analysis to determine the effect of replacing beef with alternative sources. Having in mind this study, it can be concluded that the real consumption pattern in Galicia is far from the recommended one, with worse environmental and nutritional quality. The promotion of social awareness policies to guide consumers in the choice a healthier and more environmentally sustainable dietary pattern should be advisable for regional decision-makers as well as for those who wish to promote adherence to the Atlantic diet in other regions and countriesThis research has been supported by a project granted by Xunta de Galicia (project ref.

Towards an environmentally sustainable and healthy Atlantic dietary pattern: Life cycle carbon footprint and nutritional quality

Production and consumption of food has a significant effect on climate change. The effect of different consumption habits on the environment should not be under estimated, as there are different studies that mention the environmental impact associated with different foods, especially those of animal origin. The analysis of the Atlantic diet (AD), as the most common dietary pattern in Northwestern Spain, serves as an example of a diet with a high consumption of local, fresh and seasonal products, home cooking and low-processed foods. The evaluation was carried out by quantifying the carbon footprint following the Life Cycle Analysis methodology and identifying its nutritional quality according to the value of the Nutrient-rich Dietary index (NRD9.3.). According to the main results, the consumption of livestock products and shellfish is responsible for most GHG emissions (70% of the total). The basic ingredients of the AD, such as vegetables and legumes, make a relatively minor contribution (with an impact of 30% of the total) to the total carbon footprint of 3.01 kg CO2eq·person−1·day−1. As regards nutritional quality, AD has a high nutritional score (474), mainly due to the low intake of sodium, added sugars and saturated fats (nutrients to be limited in healthy diets). In general, both the carbon footprint and the nutritional index score are consistent with those of other studies on the Mediterranean diet, which has been recognised as beneficial. Therefore, it can be concluded that the AD may be recommended from a nutritional and environmental point of view, mainly due to the high intake of fish and vegetables. The communication of this valuable environmental and nutritional information to consumers should be taken into account when considering strategic actions for the adoption of healthy and sustainable dietary patternsThis research has been supported by a project granted by Xunta de Galicia (project ref.

Efficiency assessment of diets in the Spanish regions: A multi-criteria cross-cutting approach

Food systems are one of the main drivers of the global greenhouse gases emissions from anthropogenic sources, which could be aggravated by the projected increase in world population. Hence, the adoption of sustainable diets that guarantee good and accessible nutrition and a low environmental impact is an increasingly important need. This goal is, by nature, a multi-dimensional and multi-criteria challenge that should take into account nutritional, environmental and socio-economic aspects. In this sense, this work proposes a novel methodological framework that involves the use of Data Envelopment Analysis for the efficiency assessment of dietary patterns integrating nutritional (Nutrient Rich Diet 9.3 index), environmental (carbon footprint) and socio-economic criteria (number of deaths due to tumours of the digestive system, obesity-related health expenditure, and number of persons with food shortages). The applicability of this methodology is proven through the case study of the dietary patterns of the 17 Spanish autonomous regions. The analysis reveals the existence of seven autonomous regions with sustainable dietary patterns. Furthermore, most regions have multi-criteria efficiency scores above 0.60, which suggests the presence of relatively good dietary habits in Spain. Overall, it is concluded that the proposed methodology is a viable and valuable tool for benchmarking dietary patterns under multiple cross-cutting criteriaThis research has been supported by a project granted by Xunta de Galicia (project ref.

Environmental assessment of menus for toddlers serviced at nursery canteen following the Atlantic diet recommendations

Menus served at public services can be considered as a good opportunity for consumers to demand a service that ensures healthy and environmentally friendly food. It is especially in the sector of nurseries and schools, where these demands make the most sense since they call for the protection of particularly vulnerable population: children. The purpose of this study is to analyze the biweekly menus served at a public Spanish nursery canteen considering the link with the two most recognized environmental indicators: the consumptive water footprint (WF) and the carbon footprint (CF). The WF and CF of the menus vary considerably between menus (619–1359 L·menu−1 and 0.75–2.95 kg CO2eq·menu−1). The assessment has identified non-dairy sources of protein and dairy-based products as the key food categories in all menus. Menus with more meat (mostly beef) and dairy products (mainly cheese) were associated with higher impacts. That is, the average impact of menus with beef is about 2 times greater than the one of all other menus. The distribution and cooking stages presented negligible contributions in terms of greenhouse gases emissions, mainly due to the consumption of local/regional products and low-energy intensive cooking techniques. The most important strategy for reducing environmental impacts is based on reducing the frequency of consumption of beef, so that poultry and lean pork are consumed alternately. This reduction should not compromise the necessary protein intake for toddlers. Attention should also be paid to afternoon snacks that are rich in cold meat and dairy products. Considering these issues, significant reductions in WF and CF indicators could be achieved, up to 550 L·menu−1 and 0.70 kg CO2eq·menu−1. Since eating habits introduced at an early stage are more likely to develop into adult behaviour, children canteen services are an excellent opportunity to promote healthy eating habits in children and their familiesThis research has been partially supported by a project granted by Xunta de Galicia (project ref.

Multi-product strategy to enhance the environmental profile of the canning industry towards circular economy

The sustainable and continued production of enough food to feed the entire world's population is one of the main concerns in the food industry. Spain, and in particular Galicia, which is an eminently fishing region characterised by the consumption of large quantities of fish, both fresh and processed, must face the challenge of shifting its seafood productive fabric towards a circular economy. To achieve this objective, the first task is to demonstrate that circular economy principles allow to reduce the environmental impacts associated with seafood production. In this sense, this study proposes the environmental evaluation of the skipjack tuna (Katsuwonus pelamis) value chain within a canning industry located in Galicia through the LCA methodology from an attributional perspective, including the valorisation processes for biowaste (edible and inedible by-products). Results indicate that the main crucial subsystems of the value chain are tuna fishing and the canning process, as it was expected considering other similar studies on seafood products. Moreover, this specific case study demonstrates that the multi-product strategy applied to the canning sector is environmentally viable. Thus, although the environmental impacts of the entire system are increased by including further valorisation operations, the environmental loads assigned to the main product (canned tuna) decrease compared to the one-product system by assigning environmental burdens to other value-added products (tuna pâté, fishmeal, and fish oil)This research was supported by the EAPA_576/2018 NEPTUNUS project, supported by Interreg Atlantic Area.
