Associação entre o consumo alimentar com o declínio cognitivo e as demências: um protocolo de revisão sistemática. Contribuciones a las ciencias sociales, v. 17, p. e5395, 2024.

Acesso em: 29 nov. 2024.https://repositorio.ufrn.br/handle/123456789/62533Studies demonstrate the association between diet and brain health. High consumption of ultra-processed foods (UPF) is one of the potential factors contributing to increased risk for cognitive decline and dementia. The aim of this work is to establish a systematic review protocol to examine whether there is an association between the type of food processing and cognitive decline and dementia in adults and the elderly.The present protocol for the systematic review was developed in accordance with the recommendations of the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) checklist of 2015. A systematic literature search will be conducted in the Web of Science, Scopus, PubMed/MEDLINE, EMBASE, and Latin American and Caribbean Health Sciences Literature (LILACS) databases. Included in this review will be observational studies (cohort, case-control, and cross-sectional), employing a quantitative approach, which present in their results therelationship between food processing types and cognitive decline and dementia, without limitation of causes. Additionally, studies published in full in scientific journals will be included.The preliminary literature review provides us with a panorama that partially addresses our guiding question, revealing an association between dietary intake, the nature, extent, and type of food processing, and cognitive decline, as well as dementia of all causes, notably Alzheimer's Disease and Vascular Dementia.Attribution-NonCommercial 3.0 Brazilhttp://creativecommons.org/licenses/by-nc/3.0/br/Alimentos ultraprocessadosClassificação novaDeclínio cognitivoDemênciaDoenças crônicas não transmissíveisProcessamento de alimentosarticlehttps://doi.org/10.55905/revconv.17n.3-060
