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.

Food, Sustainability, and Public Health: Linking SDGs for Global Nutrition and Responsible Consumption
This Collection, which differs from other existing food security and sustainability Collections, emphasizes the existing links between sustainable and healthy food production and consumption, exemplified by the Mediterranean Diet, in its cultural, societal, and preventive health dimensions; and Public Health, considered beyond human health to also include animal, plant, and environmental health, in a One Health and Planetary Health approaches.
Thus, with this Collection we intend to publish high quality research, concerning strategies that allow achieving the goals set out in SDGs 2, 3 and 12, which are linked among each other by the theme “Food”, and their relationship with others SDGs, namely 13 and 15. However, other approaches included in the other SDGs, but which somehow have associated food/nutrition issues and optimization of natural resources are welcomed, accepting manuscript proposals, in the form of original research papers, review articles and systematic reviews, including but not limited to the following topics:
• Access for all people, particularly the ones at risk, to a quantity of food that meets the nutritional needs of each group, or growth phase/physiological state;
• Implementation of resilient agricultural practices that increase productivity and production, that help maintain ecosystems, that strengthen the capacity to adapt to climate change, extreme weather conditions, droughts, floods and other disasters, and that progressively improve quality of earth and soil;
• Maintenance of the genetic diversity of seeds, cultivated plants, farmed and domesticated animals and their respective wild species, managed appropriately at the national, regional and international levels, and ensuring access and fair and equitable benefit sharing the use of genetic resources and associated traditional knowledge;
• Premature mortality, non-communicable diseases, mental health and regular and nutritious food;
