Ortolá R et al. – Researchers analyzed data from 2,042 people aged ≥ 60 years enrolled in the Seniors-ENRICA cohort in 2008-2010 (wave 0) and followed-up in 2012 (wave 1) and 2015 (wave 2) were analyzed to investigate the relationship between alterations in diet quality and unhealthy aging. They found that, among the elderly, adopting a better diet was related to less deficit accumulation, especially functional decline. Moreover, enhancing dietary habits may prevent unhealthy aging. These results have clinical significance because it was observed that the deficit accumulation index reduces an average of 0.74 yearly.
