Deciphering the impact of COVID‑19 pandemic on food security across different socioeconomic strata in Chile
Published in Agricultural & Food Science and Economics
Chile, classified as a developing country, is considered as one of the strongest states in Latin America, despite its relatively low levels of income redistribution. Over the period spanning from 1964 to 2017, household income dynamics in Chile reveal a trend of subdued growth in the lower quintiles in contrast to the more pronounced expansion of household income within the top 1%, as evidenced by fiscal income series. As inflation rose during the pandemic of COVID-19, a differential impact over food security was expected across different socioeconomic strata.
Key findings
- Raw food spending dominates low-income diets. On average, restaurant expenditures constituted a larger share of total food expenditure in the highest-income households (26.7%) compared to the lowest-income households (8.6%). In contrast, raw & processed foods made up 51.9% of highest-income households’ food expenditure, but 74.3% of the lowest-income households. This suggests that assessing food security should focus on raw & processed foods, particularly in lower-income households.
-Meat dominates budgets across all incomes. Monthly expenditures on raw and processed foods by income quintile from 2006 to 2021 showed stable purchasing patterns (Fig. 1), where Meats consistently commanded the largest share of households food budgets regardless of income quintile, ranging from 25.1% to 26.4%.
As household income increased, there was a noticeable reduction in the proportion of budget allocated to Cereals & grains (p-value = 0.0073), and, to a lesser extent, Fruits and vegetables (p-value = 0.0071). In contrast, higher-income households allocated a larger share to Dairy and eggs (p-value = 0.0089), Other foods (p-value = 0.0073), Processed fruits and vegetables (p-value = 0.0076), and Fish & seafood (p-value = 0.0105). These differences suggest
that higher-income households purchase a broader diversity of foods. Nevertheless, Meats, Cereals & grains, and Fruits & vegetables remain the primary components of food expenditures, regardless of household income.

-Post-pandemic, spending gap narrowed under strain. Generally, lower-income households spent less across all categories (p-value < 0.0001), but the spending gap between lower- and higher-income households narrowed post-pandemic. Pre-pandemic, quintile I spent 44% of what quintile V spent on raw & processed foods, rising to 50% post-pandemic. It was observed that was due to households experiencing a greater price increase, contributing to narrowing the expenditure gap, as lower-income households had to pay disproportionately more to access similar quantities of food post-pandemic.
-Reduced nutrient acquisition per household, but per capita kilocalories rose. Analysis of nutrients from household monthly acquisitions pre- and post-pandemic revealed a trend of reduced acquisition across all income levels after the pandemic. However, due to smaller household sizes, kilocalorie availability per person has increased, a narrowing of the gap between quintiles I and V was observed.
-Stable food preferences where income influences specific choices. Comparison of food subcategories (Fig. 2) showed consistent acquisition patterns both pre- and post-pandemic, with fresh vegetables, bread, fresh fruits, chicken and beef being the top items, in that order. Prices increases did not disrupt these trends. Interestingly, higher-income households allocate more to beef and processed meats, while lower-income households prioritize chicken. In the Fruit & Vegetables category, higher-income households showed a
preference for fresh fruits over fresh vegetables, whereas lower-income households opt for more fresh vegetables.

In conclusion
Overall, significant disparities in household food expenditure and economic access to food are evident across incomes quintiles in Chile. Lower-income households allocate a larger proportion of their budgets to staple foods like cereals, meats and fruits & vegetables, while higher-income households spend more on non-essential foods. Post-pandemic, lower-income households experienced greater price increases, narrowing the spending gap but without improving dietary diversity, despite government financial support. These findings highlight the importance of targeted policies that address both economic access to essential foods and the persistent nutritional challenges faced by vulnerable populations in Chile. Agricultural production and prices of cereals, meats and fresh fruits & vegetables likely play a critical role in influencing food security. Public policies that integrate agrarian, food and nutritional security have the potential to contribute to reducing poverty in its classical interpretation.

Exploring the Role of Functional Foods in Addressing Modern Nutritional Gaps and Health Challenges
The increasing prevalence of chronic diseases, dietary insufficiencies, and lifestyle-related health challenges has intensified the global focus on functional foods. These foods, fortified with bioactive compounds, hold the potential to bridge the gap between nutrition and therapeutic intervention, addressing both preventative and remedial health concerns. This collection, "Exploring the Role of Functional Foods in Addressing Modern Nutritional Gaps and Health Challenges," aims to curate cutting-edge research that explores the development, efficacy, and societal impact of functional foods. We invite submissions that delve into the biochemical mechanisms, clinical outcomes, and technological innovations related to functional food production and consumption.
This Collection stands out by bridging the gap between functional food research and real-world applications for global health challenges. Unlike existing studies that focus on either biochemical mechanisms or clinical outcomes in isolation, our approach integrates multiple perspectives, including food technology, public health, sustainability, and consumer behavior. Additionally, the direct alignment with SDGs (2, 3, and 12) makes this collection unique in its scope and impact. SDG 2 (Zero Hunger) – Functional foods as a means to address micronutrient deficiencies and improve global nutrition. SDG 3 (Good Health and Well-being) – The role of functional foods in preventing and managing chronic diseases. SDG 12 (Responsible Consumption and Production) – Sustainable sourcing, production innovations, and food waste reduction in functional food development.
By fostering interdisciplinary dialogue, this collection aspires to advance the understanding and application of functional foods in mitigating modern nutritional challenges. To ensure a well-rounded collection, we propose the following key subtopics:
• Bioactive Compounds and Nutritional Enhancement: polyphenols, peptides, probiotics, and prebiotics in functional foods;
• Dietary Interventions and Health Benefits: functional foods for metabolic disorders, cardiovascular health, gut microbiota modulation;
• Technological Innovations in Functional Food Production: novel food processing methods, encapsulation, and bioavailability improvement;

Probiotics and Human Health: Current Innovation, Safety and Challenges
In recent years, there has been growing understanding and evidences about human health and its relationship to food. Although the battle against a number of illnesses continues likewise lactose intolerance, diarrhea, inflammatory bowel disease, irritable bowel syndrome, overweight and diabetes, cancer, colorectal cancer and coronary artery disease. Therefore, scientific communities are aiming to employ a cutting-edge dietary-based strategy such as probiotics to create a better human health and well-being. Since, such innovative dietary approaches not only offer nutritional benefits but it provide various health-giving properties. Over the last few years, probiotics have gained a lot of popularity due to the growing scientific evidences demonstrating their potential therapeutic benefits. The Food and Agriculture Organization has described probiotics as "live micro-organisms that, when given in sufficient amounts, confer a health benefit on the host." Many fermented foods contain live microorganisms that are genetically related to probiotic strains. Foods that have undergone fermentation using probiotic strains have shown to improve nutritional value and functional properties by converting substrates into bioactive and bioavailable end-products. Furthermore, probiotic supplementation in diet have also demonstrated a promising strategy against a variety of enteric pathogens because of their unique ability to either alienate pathogens or compete with the pathogenic microbiota for adhesion sites, or to stimulate, modulate, and regulate the host's immune response by triggering the activation of particular genes both inside and outside the host intestinal tract. Probiotics supplementation can be done by adding them to meals and beverages, whether they are dairy- or non-dairy-based. Furthermore, Probiotics' sensitivity to gastrointestinal stressors and processing conditions pose the biggest obstacle to their use in the food sector. In addition, there are several safety issues encountered during its administration. While at the same time, it is necessary to update, reform, and tighten the policies and regulations for the food manufacturers dealing with such functional foods to protect consumers from false and misleading claims.
Hence, various scientific evidence suggest that probiotics benefits in preserving and improving human health without or minimal negative effects. In addition, it will help in improving the overall health of gut microbiota leading to reduction in various chronic illness. Therefore, the current issue will focus on isolation, identification and characterization of probiotics strains, development of various probiotics or plant based probiotics, application of probiotics strains in various metabolic disorders as well as uncovering the potential of probiotics as a targeted therapy. It is hoped that prominent scientists working in this area will be able to contribute to novel findings and results within this field. In this topical collection, we welcome the submission of original research or review article with a focus on the following subjects as mentioned below (but not limited to):
• Current innovation and product developments for production of probiotics.
