Nutrient intake was estimated from 3-d food records at baseline and from two 3-d food records at 6 mo. Normal calcium intake was 1.0 g/d; high calcium intake was 1.8 g/d. Includes 48 mg phosphorus, 10 μg vitamin D, 100 mg magnesium, or 10 μg vitamin K from multivitamin-minerals; does not include salt from shaker. No significant differences were observed between the groups at baseline.
Comparison of percentage changes between the 3 groups (nonparametric one-factor ANOVA).
(all such values).
Significantly different from baseline value, P < 0.05.
Significantly different from WM, P < 0.05.
Includes supplemental calcium at baseline and during study period of 0.4 g/d (normal calcium) and 1.2 g/d (high calcium). Mean (±SD) calcium intakes before supplementation (prestabilization): WL high calcium: 951 ± 334 mg/d; WL normal calcium; 1155 ± 500 mg/d; and WM normal calcium; 1024 ± 381 mg/d.
