Quick Summary

In this prospective cohort study in older adults, higher intakes of protein from either plants or animals were associated with increased odds of an improvement in nutritional status, but the association was stronger for plant-based proteins.

What was studied?

Whether intakes of animal-based protein and plant-based proteins are associated with changes in nutritional status.

Analyses were also conducted to determine whether replacing animal-based proteins with plant-based proteins is associated with changes in nutritional status, or if the intake of specific sources of animal-based and plant-based proteins is associated with changes in nutritional status.
