Special Issue Information

Dear Colleagues,

Interest in sustainable and healthy diets has evolved significantly over the years following scientific research and public awareness towards emerging challenges related to human health and wellbeing combined with environmental sustainability on a planetary as well as a local level.

Sustainable diets, by definition, are closely linked to human health since they promote the consumption of nutritionally adequate, safe, and healthy foods while minimizing environmental impacts. They promote nutritional patterns rich in fruits, vegetables, whole grains, and healthy fats, with moderate or minimal amounts of meat, saturated oils, added sugars, and processed foods. Various well-known diets, such as the Mediterranean diet, the Nordic diet, Asian diets, vegetarian diets, vegan diets, and others, follow sustainable and healthy dietary patterns. Traditional diets, which originated from or are adapted to local sustainable agrifood systems, include healthy dietary choices, based on indigenous knowledge and cultural heritage. Contemporary healthy plant-based food consumption combined with zero-waste and zero-plastic initiatives reduces the environmental impact of food production systems. Do these different aspects of sustainable diets manage to have an impact on complex health issues? Are global guidelines on sustainable diets and/or the Sustainable Development Goals (SDGs) adequate to transform regional and local behaviors around the world? Could sustainable dietary habits change food production, affecting our adaptation to environmental challenges ahead?

This Special Issue aims to enhance understanding of the interconnection between human nutrition and environmental sustainability following the guidelines of sustainable diets as they should or could be implemented across global, regional, and local scales. Topics of interest include, but are not limited to, those described above. Thus, all types of quantitative and qualitative studies are welcomed.

Background/Objectives: Personalized nutrition programs enhanced with artificial intelligence (AI)-based tools hold promising potential for the development of healthy and sustainable diets and for disease prevention. This study aimed to explore the impact of an AI-based personalized nutrition program on the gut microbiome of healthy individuals. Methods: An intervention using an AI-based mobile application for personalized nutrition was applied for six weeks. Fecal and blood samples from 29 healthy participants (females 52%, mean age 35 years) were collected at baseline and at six weeks. Gut microbiome through 16s ribosomal RNA (rRNA) amplicon sequencing, anthropometric and biochemical data were analyzed at both timepoints. Dietary assessment was performed using food frequency questionnaires. Results: A significant increase in richness (Chao1, 220.4 ± 58.5 vs. 241.5 ± 60.2, p = 0.024) and diversity (Faith’s phylogenetic diversity, 15.5 ± 3.3 vs. 17.3 ± 2.8, p = 0.0001) was found from pre- to post-intervention. Following the intervention, the relative abundance of genera associated with the reduction in cholesterol and heart disease risk (e.g., Eubacterium coprostanoligenes group and Oscillobacter) was significantly increased, while the abundance of inflammation-associated genera (e.g., Eubacterium ruminantium group and Gastranaerophilales) was decreased. Alterations in the abundance of several butyrate-producing genera were also found (e.g., increase in Faecalibacterium, decrease in Bifidobacterium). Further, a decrease in carbohydrate (272.2 ± 97.7 vs. 222.9 ± 80.5, p = 0.003) and protein (113.6 ± 38.8 vs. 98.6 ± 32.4, p = 0.011) intake, as well as a reduction in waist circumference (78.4 ± 12.1 vs. 77.2 ± 11.2, p = 0.023), was also seen. Changes in the abundance of Oscillospiraceae_UCG_002 and Lachnospiraceae_UCG_004 were positively associated with changes in olive oil intake (Rho = 0.57, p = 0.001) and levels of triglycerides (Rho = 0.56, p = 0.001). Conclusions: This study highlights the potential for an AI-based personalized nutrition program to influence the gut microbiome. More research is now needed to establish the use of gut microbiome-informed strategies for personalized nutrition. Full article

Background/Objectives: Plant-based diets are associated with human and planetary health. However, the overall quality of these diets may depend on the proportion of ultra-processed foods (UPFs). This study investigates the association between UPF consumption and plant-based diet quality in Australian adults. Methods: Analysis was conducted on 9111 participants (aged ≥ 19 years) from the National Nutrition and Physical Activity Survey 2011–2012. Food items reported from a 24 h recall were classified using the NOVA system, and the contribution of UPFs to total energy intake was calculated. Plant-based diet quality was examined using the overall plant-based diet index (PDI), healthy PDI (hPDI), and unhealthy PDI (uPDI). Multiple linear regression models were used to examine the association between the UPF intake and PDI, hPDI, uPDI, and their score components. Results: The proportion of energy from UPFs was positively associated with the uPDI (β = 0.80; 95% CI 0.72, 0.89) and negatively associated with the PDI (β = −0.13; 95% CI: −0.22, −0.04) and the hPDI (β = −0.65; 95% CI: −0.73, −0.57). All score components of the PDI, hPDI and uPDI, except whole grains, legumes and fruit juices, significantly contributed to these associations. The sugars and syrups group contributed most to the positive association between UPFs and the uPDI (β = 6.47; 95% CI: 6.07, 6.87) and the negative association of UPFs and the hPDI (β = −6.47; 95% CI: −6.07, −6.87). Conclusions: Higher consumption of UPFs was associated with a lower plant-based diet quality. These findings have implications for the design of dietary interventions that encourage the consumption of minimally processed plant-based foods. Full article
