Adherence to the healthy and sustainable dietary recommendations for the Spanish population and all-cause mortality.

Introduction And Objectives: The healthy and sustainable dietary recommendations for the Spanish population have recently been launched. We aimed to develop a food-based dietary index to measure adherence to these guidelines and assess its association with all-cause mortality.

Methods: Data were drawn from 11 904 individuals, representative of the Spanish population aged 18 and older, recruited between 2008 and 2010, and followed-up until 2022.

Plant-Based Diets and Risk of Multimorbidity: The Health and Retirement Study.

Background: Plant-based diets have gained attention due to their beneficial effects against major chronic diseases, although their association with multimorbidity is mostly unknown.

Objectives: We examined the association between the healthful (hPDI) and unhealthful plant-based diet indices (uPDI) with multimorbidity among middle-aged and older adults from the United States.

Methods: Data on 4262 adults aged >50 y was obtained from the 2012-2020 Health and Retirement Study (HRS) and 2013 Health Care and Nutrition Study (HCNS).

Diet Quality and Multimorbidity in Older Adults: A Prospective Cohort Study.

Background: The role of diet quality in the accumulation of multiple chronic conditions is mostly unknown. This study examined diet quality in association with the number of chronic conditions and the rate of multimorbidity development among community-dwelling older adults.

Methods: We used data from 2 784 adults aged ≥65 years from the Seniors-ENRICA 2 cohort.

Cross-sectional Association Between Plasma Biomarkers and Multimorbidity Patterns in Older Adults.

Multimorbidity is the simultaneous presence of 2 or more chronic conditions. Metabolomics could identify biomarkers potentially related to multimorbidity. We aimed to identify groups of biomarkers and their association with different multimorbidity patterns.

Leucine Intake and Risk of Impaired Physical Function and Frailty in Older Adults.

Background: Leucine is suggested to play a central role in age-related physical decline, but the effect of dietary leucine intake on physical functioning is uncertain. We examined the prospective association between dietary leucine intake and impaired lower-extremity function (ILEF) and frailty in older adults.

Methods: We used data from 2 956 adults aged ≥60 and older from the Seniors-ENRICA cohort.

Association of Zinc Intake With Risk of Impaired Physical Function and Frailty Among Older Adults.

Background: Zinc could be a target nutrient in the prevention of physical impairment and frailty in older adults due to its anti-inflammatory/antioxidant properties. However, prospective studies evaluating this inquiry are scarce. Thus, we aimed to assess the association between zinc intake and impaired lower-extremity function (ILEF) and frailty among community-dwelling older adults.

Plasma Amino Acids and Risk of Impaired Lower-Extremity Function and Role of Dietary Intake: A Nested Case-Control Study in Older Adults.

Introduction: Amino acids are key elements in the regulation of the aging process which entails a progressive loss of muscle mass. The health effects of plasma amino acids can be influenced by dietary intake. This study assessed the prospective association between amino acid species and impaired lower-extremity function (ILEF) in older adults, exploring the role of diet on this association.
