Animal vs. plant protein reveals a surprising testosterone divide
The Brief
- A study of more than 2,500 men linked higher animal protein intake, particularly from dairy, to lower testosterone levels.
- The reported association for plant protein is cut off in the available source excerpt.
- The source describes an association, not a proven cause-and-effect relationship.
Why it matters
Diet is a modifiable factor, so an association between protein sources and testosterone could inform further research on male hormone health, though the available excerpt does not establish causation.
Who’s affected
- men interested in diet and hormone health
- nutrition and endocrinology researchers
A surprising new study suggests that where men get their protein may be linked to their testosterone levels. Researchers studying more than 2,500 men found that higher animal protein intake, particularly from dairy, was associated with lower testosterone, while plant protein was…
