OBJECTIVE: This prospective study aimed to investigate the association of the dietary plant-to-animal protein intake ratio with the incidence of slow gait speed among older adults. METHODS: Data from 997 adults [50.7% male, mean age 65.5 (SD 6.9) y] with a baseline gait speed ≥0.8 m/s were derived from the Longitudinal Aging Study Amsterdam. The dietary plant-to-animal protein intake ratio was calculated from a 238-item food frequency questionnaire completed from 2014 to 2015. Gait speed was measured at baseline and at three 3-y follow-up waves using a 6-meter walk test. Cox proportional hazards models estimated the association between protein ratio quintiles and incident slow gait speed (<0.8 m/s), while adjusting for demographic and lifestyle factors and testing for interaction by sex, overall diet quality, protein intake, and baseline gait speed. RESULTS: The median dietary plant-to-animal protein intake ratio was 0.67 [interquartile range (IQR): 0.52 to 0.86]. During follow-up, slow gait speed (<0.8 m/s) developed in 415 participants (41.6%). No significant association was found between the protein ratio and incident slow gait speed. The adjusted hazard ratio of the highest (ratio > 0.91) compared with the lowest (ratio ≤ 0.49) quintile was 0.98 (95% confidence interval: 0.68, 1.42; trend across quintiles P = 0.89). No significant interactions were observed with sex, overall diet quality, or total protein intake. A higher plant-to-animal protein ratio was suggested to be associated with a lower risk of incident slow gait speed in those with relatively faster baseline gait speed, although associations were not statistically significant. CONCLUSIONS: Among Dutch older adults, the dietary plant-to-animal protein intake ratio was not associated with the risk of developing slow gait speed, suggesting that a more sustainable diet including higher plant protein intake may not compromise physical functioning in older adults.","is_dataset_classified":null,"base_score":0.6931471805599453,"endowment":0.6931471805599453,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"41380850","pmcid":"PMC12975347","openalex_id":"https://openalex.org/W4417164337","authors":[],"funders":[{"funder_name":"Nederlandse Organisatie voor Wetenschappelijk Onderzoek","grant_id":"480-10-014","title":"New cohorts of young old in the 21st century"},{"funder_name":"European Commission Seventh Framework Programme for Research and Technological Development Health","grant_id":"613598","title":null},{"funder_name":"European Commission","grant_id":"","title":null},{"funder_name":"Netherlands Ministry of Health Welfare and Sport","grant_id":"","title":null},{"funder_name":"Netherlands Organisation for Health Research and Development","grant_id":"","title":null}],"total_grants":5,"fwci":1.0701,"citation_percentile":0.82885143,"influential_citations":0,"citation_trend":[{"year":2026,"count":1}],"oa_status":"hybrid","license":"cc-by","oa_locations":[{"url":"https://doi.org/10.1016/j.tjnut.2025.101266","host_type":"journal"},{"url":"https://doi.org/10.1016/j.tjnut.2025.101266","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0022316625007722?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0022316625007722?httpAccept=text/plain","host_type":"publisher"},{"url":"https://pubmed.ncbi.nlm.nih.gov/41380850","host_type":"repository"},{"url":"https://research.vu.nl/en/publications/71c137b2-59de-49b8-a14a-4757c102a0ad","host_type":"repository"},{"url":"https://pubmed.ncbi.nlm.nih.gov/41380850/","host_type":"repository"},{"url":"https://hdl.handle.net/1871.1/71c137b2-59de-49b8-a14a-4757c102a0ad","host_type":"repository"},{"url":"https://europepmc.org/articles/PMC12975347","host_type":"Europe_PMC"},{"url":"https://europepmc.org/articles/PMC12975347?pdf=render","host_type":"Europe_PMC"},{"url":"https://pmc.ncbi.nlm.nih.gov/articles/PMC12975347/","host_type":""}],"fields_of_study":["Nutritional Studies and Diet","Physical Activity and Health","Nutrition and Health in Aging","0402 animal and dairy science","04 agricultural and veterinary sciences"],"mesh_terms":["Walking Speed","Animal Proteins, Dietary","Aged","Diet","Dietary Proteins","Female","Gait","Humans","Longitudinal Studies","Male","Middle Aged","Netherlands","Prospective Studies","Plant Proteins, Dietary","Incidence"],"keywords":["Incidence (geometry)","Preferred walking speed","Gait","Dietary protein","Association (psychology)","Food intake","Old Age","Physical performance","Sustainable Diet","Plant-based Protein","Planetary Diet","Nutritional Epidemiology"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-06T09:52:55.427032Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
