Another new study using the data on Women from the WHI.

Dietary protein intake in midlife in relation to healthy aging - results from the prospective Nurses' Health Study cohort

https://pubmed.ncbi.nlm.nih.gov/38309825/

Conclusions: Dietary protein intake, especially plant protein, in midlife, is associated with higher odds of healthy aging and with several domains of positive health status in a large cohort of female nurses.

Dietary protein intake is important, full stop. The difference between animal, dairy and plant protein was not significant. Considering this was the Harvard nurses study, where they were also analyzing diet, fats, CVD, HRT some participants may have leaned to plant protein. All the other caveats about using food frequency questionnaires, etc but more protein leads to healthier weights and lower risk of chronic diseases.
Good to have a study on aging women and protein rather than only young male bodybuilders.
