To evaluate the association between ultra-processed food consumption and adherence to the EAT- diet in a representative sample of the Brazilian population.
The study used data from the Brazilian National Dietary Survey 2017-2018 and employed linear regression models to evaluate the association between ultra-processed food consumption and adherence to the EAT- diet, as measured by the Nova food system and Planetary Health Diet Index (PHDI), respectively.
Nationally representative sample of the Brazilian population.
The study included 46 164 Brazilians ≥ 10 years old.
The average PHDI total score was 45·9 points (95 % CI 45·6, 46·1). The ultra-processed food consumption was, with dose-response, inversely associated with the adherence to the EAT- diet. The PHDI total score was 5·38 points lower (95 % CI -6·01, -4·75) in individuals in the highest quintile of consumption of ultra-processed foods, as compared to those in the first quintile. The PHDI score was also inversely associated with the share of processed culinary ingredients and processed foods and positively associated with the share of unprocessed or minimally processed foods.
Our study showed an inverse relationship between the consumption of ultra-processed foods and the adherence to a healthy and sustainable diet.
评估在巴西代表性人群样本中，超加工食品消费与 EAT-饮食依从性之间的关联。
本研究使用了 2017-2018 年巴西国家饮食调查的数据，并采用线性回归模型评估了超加工食品消费与 EAT-饮食（分别用新食品体系和行星健康饮食指数[PHDI]衡量）之间的关联。
巴西人口的全国代表性样本。
本研究纳入了 46164 名≥10 岁的巴西人。
PHDI 总分平均为 45.9 分（95 % CI 45.6，46.1）。超加工食品消费与 EAT-饮食的依从性呈负相关，且呈剂量反应关系。与第一五分位数相比，超加工食品消费最高五分位数的个体 PHDI 总分低 5.38 分（95 % CI -6.01，-4.75）。PHDI 评分与加工烹饪成分和加工食品的比例呈负相关，与未加工或最低限度加工食品的比例呈正相关。
本研究表明，超加工食品的消费与健康和可持续饮食的依从性呈负相关。
