Special Issue Information

Dear Colleagues,

Nutrition is a key factor in achieving prolonged healthy aging, maintaining good functionality, and delaying frailty. On the other hand, older people are a high-risk population for developing malnutrition since several risk factors for it, such as polypharmacy, comorbidity, dementia, and others, are very prevalent in these individuals. In the last two decades, a substantial amount of evidence has shown that healthy lifestyle habits (mainly a balanced diet and staying physically active) improve the aging process of human beings. Therefore, deepening our knowledge of the relationship between nutrition and aging will help us propose personalized non-pharmacological treatments that could delay this process. The chronic and persistent pro-inflammatory state is a common element of many diseases associated with aging, and some dietary patterns such as the Mediterranean diet also have an anti-inflammatory function. Likewise, the microbiota–gut–brain interaction also seems to be a key element for explaining the relationship between health, disease, and aging. For all these reasons, we invite you to participate in this Special Issue of Nutrients to learn how to improve the quality of life, functionality, and survival of older people by optimizing their dietary patterns and nutritional status.

Eating out of home (EOH), with its diverse food options, can benefit those with difficulty preparing their meals, especially older adults. Oral health status may be a determinant of EOH, as food accessibility is influenced by oral health, but this association remains unclear. This cross-sectional study used merged data from two national statistical surveys conducted in 2019. Participants were individuals aged ≥ 65 years who responded to both surveys. The frequency of EOH (<once/week or ≥once/week) was the dependent variable. The number of teeth was used as the independent variable (≥20, 10–19, 1–9, and 0). Prevalence ratios (PRs) and 95% confidence intervals (CIs) were calculated using multivariate Poisson regression analysis to identify the association between EOH and the number of teeth, adjusting for possible confounders. We analyzed 2164 participants (mean age = 74.0, women 52.4%). Of these, 456 (21.1%) participants were EOH ≥ once/week; 1142 (52.8%) participants had ≥20 teeth. Compared to those with ≥20 teeth, those with <20 teeth had a lower prevalence of EOH ≥ once/week (10–19: PR = 0.89, 95% CI = 0.72–1.09, 1–9: PR = 0.67, 95% CI = 0.51–0.89, and 0: PR = 0.53, 95% CI = 0.36–0.77, respectively). We observed an association between fewer teeth and a lower frequency of EOH. Full article
