[Articles] Affordability and nutritional challenges for the future of EAT diets: an economic modelling analysis

Although dietary shifts towards the 2025 EAT–Lancet Commission diet could offset some of the increases in prices seen in a business-as-usual world, we observed unintended effects on nutrient availability ratios, especially in lower-income countries. The decreasing price index for the cheapest two commodities reflects market adjustments to changes in demand and supply under scenario assumptions aligned with 2025 EAT–Lancet Commission goals for jointly improved human and environmental health. The observed nutrient deficiencies suggest the 2025 EAT–Lancet Commission diet limits on animal-sourced foods might be too strict for lower-income countries, which could exacerbate nutrient deficiencies in contexts where access to animal sourced foods is already low (eg, vitamin A), especially if there is no access to supplementation for meeting these nutritional requirements or other sources of dietary nutrients.
