Ortola R, Struijk EA, García-Esquinas E, et al. - Experts evaluated the correlation between changes in animal and vegetable protein intake and unhealthy aging in older adults. In this study, the enrolled a total of 1,951 individuals aged ≥ 60 years between 2008 and 2010 (wave 0) and followed-up in 2012 (wave 1), 2015 (wave 2), and 2017 (wave 3). They assessed dietary protein intake with a validated diet history at waves 0 and 1, and unhealthy aging was measured with a 52-item health deficit accumulation index at each wave. There were no associations for animal protein. They observed less deficit accumulation over 8.2 years when substituting 1% of energy from vegetable protein for an equal amount of carbohydrate or fat, animal protein, dairy protein, or meat protein. They found that increasing dietary intake of vegetable protein may delay unhealthy aging when replacing carbohydrates, fats, or animal protein, especially from meat and dairy.
