Ortolá R, et al. - Via 2,042 individuals aged ≥60 years who recruited in the Seniors-ENRICA cohort in 2008-2010 (wave 0) and followed-up in 2012 (wave 1) and 2015 (wave 2), the researchers analyzed the correlation between modifications in diet quality and unhealthy aging. Those with a >1-point elevation exhibited lower deficit accumulation from wave 0 to wave 2 and from wave 1 to wave 2, in comparison with individuals with a >1-point decrease in Mediterranean Diet Adherence Screener or Mediterranean Diet Score. Moreover, people with a >5-point elevation in Alternate Healthy Eating Index-2010 presented lower deficit accumulation from wave 0 to wave and from wave 0 to wave 2 in contrast to those with a >5-point decrease. These outcomes were mostly because of a strong connection between enhanced diet quality and less functional deterioration. Hence, it was concluded that adopting a more suitable diet was related to less deficit accumulation, particularly functional deterioration, in elderly people. Further, enhancing dietary habits could linger unhealthy aging. These results have clinical relevance since it was discovered that the deficit accumulation index reduced an average of 0.74 annually.
