A study published in PLOS ONE examines the impact of the COVID-19 pandemic on food quality and diversity in American households. Due to lockdowns and closures of restaurants, there was a shift to purchasing food from supermarkets, disrupting supply chains. Before the pandemic, American diets were already unhealthy, with high consumption of processed foods. The study found temporary increases in food diversity and diet quality during the pandemic, with households showing good maintenance of these factors even six months after school closures. However, there were limitations to the study, such as potential bias from stockpiling and food price inflation.
