Special Issue Information

Dear Colleagues,

As the population ages, the importance of geriatric nutrition becomes increasingly critical. Understanding what constitutes optimal nutrition for older people is more than a dietary challenge; it is fundamental to ensure a dignified and healthy later life. This Special Issue is dedicated to exploring the pivotal role of nutrition in the health and well-being of older people. We aim to provide a comprehensive platform for the latest research, insights and discussions that address unique dietary and nutritional needs and challenges in older adults.

This Special Issue seeks to illuminate the complex relationship between diet, nutrients, bioactive food components, complex dietary pattern and food policy, and age-related physiological changes, disease prevention and management, and improvements in the quality of life. We encourage submissions that cover a wide range of topics, including, but not limited to, (1) nutritional requirements for aging adults; (2) the impact of nutritional and dietary factors on chronic disease prevention and management in older people; and (3) innovative dietary strategies to mitigate the risk of geriatric syndromes.

We invite original research papers and ordinary or systematic reviews that contribute to our understanding of geriatric nutrition.

Objectives: The aim of the study was to examine the relationship between the Mediterranean diet (MD) and vascular stiffness and metabolic syndrome (MetS), as well as its components in individuals over the age of 65, overall and by sex. Methods: The subjects of the study were people over 65 years of age, with a full record of all variables analyzed from the EVA, MARK, and EVIDENT studies. Data from 1280 subjects with a mean age of 69.52 ± 3.58 years (57.5% men) were analyzed. The MD was recorded with the validated 14 item MEDAS questionnaire. MetS was defined following the guidelines of the joint scientific statement from the Programa Nacional de Educación sobre el Colesterol III. Vascular stiffness was evaluated with the VaSera VS-1500® device by measuring the cardio-ankle vascular index (CAVI) and the brachial-ankle pulse wave velocity (baPWV). Results: The mean MEDAS score was 6.00 ± 1.90, (5.92 ± 1.92 in males, 6.11 ± 1.88 in females; p = 0.036). CAVI: 9.30 ± 1.11 (9.49 ± 1.05 males, 9.03 ± 1.13 females; p = <0.001). baPWV: 15.82 ± 2.56 (15.75 ± 2.46 males, 15.92 ± 2.68 females; p = <0.001). MetS was found in 51% (49% males, 54% females; p = 0.036). Subjects with MetS had lower MD adherence and higher vascular stiffness values than subjects without MetS. Overall, we found a negative association with MD score and the number of MetS components (β = −0.168), with glycemia (β = −0.007), triglycerides (β = −0.003), waist circumference (β = −0.018), CAVI (β = −0.196) and baPWV (β = −0.065), and a positive association with HDL cholesterol (β = 0.013). Regarding sex, associations followed the same direction but without reaching statistical significance with blood glucose and triglycerides in females and with HDL cholesterol and waist circumference in males. Conclusions: The results indicate that greater adherence to the Mediterranean diet decreases vascular stiffness and the percentage of subjects with MetS, although results differed in the association with MetS components by sex.

Research on dietary fatty acids (FAs) and lung health has reported skeptical findings. This study aims to examine the causal relationship between circulating FAs and Chronic Obstructive Pulmonary Disease (COPD) onset and exacerbation, using a two-sample Mendelian Randomization (MR) analysis. Strong and independent genetic variants of FAs were obtained from the UK Biobank of European ancestry. The exposure traits included saturated FA (SFA), poly- and mono-unsaturated FA (PUFA and MUFA), omega-3 and omega-6 PUFA, docosahexaenoic acid (DHA), and linoleic acid (LA), all expressed as total FA (TFA) percentages. Summary statistics for COPD outcomes were obtained from the FinnGen consortium including COPD, COPD hospitalization, COPD/asthma-related infections, COPD-related respiratory insufficiency, and COPD/asthma/interstitial lung disease (ILD)-related pneumonia. The inverse-variance weighted (IVW) was the primary MR approach. MR-Egger regression and MR-PRESSO were utilized to evaluate heterogeneity and pleiotropy. MR-PRESSO tests suggested no obvious horizontal pleiotropy. MR results by the IVW approach indicated that the genetically high SFA/TFA levels were associated with an increased risk of COPD/asthma/ILD-related pneumonia (OR: 1.275, 95%CI: 1.103–1.474, p for FDR = 0.002). No significant relationship was observed between other types of FAs and COPD outcomes. Our MR analysis suggests that there is weak evidence that the genetically predicted high SFA/TFA was associated with an increased risk of pneumonia. Full article
