Reducing ultra-processed foods and increasing diet quality in affordable and culturally acceptable diets: a study case from Brazil using linear programming
Design culturally acceptable and healthy diets with reduced energetic share of ultra-processed foods (UPF%) at no cost increment and to evaluate the impact of the change in the UPF% on diet quality.
The mean populaiton UPF% was 23.8% - the lowest was 10%. The optimised diet cost was up to 20% cheaper than observed cost, depending on model and income level. The optimised diets had reduced UPF% and increased amounts of fruits, vegetabels, beans, tubers, dairy products, nuts, fibre, K, Mg, and vitamins A and C.
