She points out that perishables, such as fruits, vegetables, and meats, have been impacted differently than grains and other staples for two main reasons. “The first is that social distancing policies have affected work regimes and it has become more difficult to grow food and the second [is] the logistical and air freight difficulties, especially in 2020, and this has been reflected in food prices, impacting diets in Latin America.”
