Bone mineral density and bone mineral content. Bone mineral density (BMD) and bone mineral content (BMC) of the total femur, femoral neck, and distal femur for right femurs of rats in the six treatment groups after 21 weeks. N = 84 rats. Each bar in the figure is the mean with standard error for 14 femurs. Mean BMD and BMC are consistently higher for rats fed the diets containing resistant starch (solid bars) than for their counterparts (adjacent striped bars) fed the normal diets. Values not marked with the same upper-case letters (A, B, or C) differ significantly (p < 0.05) by comparison of least-square means. Inferential statistical analyses of these data by 2-way ANOVA are provided in Table 3.
