Soluble corn fiber (SCF) has been shown to enhance calcium utilization and bone properties in rats and in adolescent boys and girls.
The growing knowledge of non-digestible oligosaccharide (NDO)-related health benefits has led to the identification of other fermentable carbohydrates which may improve bone balance and bone health parameters. One such carbohydrate is the corn derivative, soluble corn fiber (SCF). Already known for its association with improved intestinal health and influence on colonic microflora content, we have been studying the effects of SCF on calcium absorption and bone health. First we found that soluble corn fiber (SCF) greatly enhanced calcium utilization and bone properties in a growing rat model. Results from this study demonstrated that SCF was capable of increasing bone mineral content, density and bone strength parameters in 4-week old, male rats. Our study in adolescent boys and girls showed a 12% increase in calcium absorption after consuming 12 g SCF for 21 days compared to a control period in a crossover design using a controlled feeding metabolic balance approach. Given these profound changes on calcium absorption and in bone, a logical next step is to study a dose-response effect of SCF on calcium absorption, bone turnover, and gut microflora in free-living adolescents.

| Calcium Absorption | The subject will be asked to consume one snack item in the morning and one snack in the evening for four consecutive weeks. After consuming the SCF product for four weeks the teen will come to Purdue University campus for 3 nights and days (e.g. Thursday noon - Sunday noon). They will reside in university residence hall or hotel near campus. Calcium Absorption testing will be done utilizing 43Ca and 44Ca. | 4 Weeks |
| Measure | Description | Time Frame |
|---|---|---|
| GI microbial changes | Fecal microbial analyses will be performed on a baseline sample collected before each 4 week consumption period to establish basal microbial profiles. Additional analyses will be performed on fecal samples collected during the 3 day clinical visit to compare microbial changes in response to SCF treatments. | 4 weeks |
