Figure 4. A low-protein diet negatively impacted bone density.
C57BL/6 mice fed a low dietary protein diet had lower total and femoral bone mass (Panels A, C) and higher levels of a marker of bone breakdown, Pyd (Panel D). The bones from these mice were also weaker with lower ultimate force at break (Panel E) and ultimate stress at break (Panel F; measurements are expressed as the means ± SEM, n=10 mice/condition, a=p<0.05).
