Whole-body calcium retention
Whole-body calcium retention; read each linked claim for the measured context and model.
1 recorded relationships. Experimental role, claim status and evidence remain attached to each record.
How nutrients influence it
Every nutrient with a recorded effect on this component, credited to the nutrient that acted rather than the chapter that recorded it. Open a nutrient to see the findings and the conditions they were measured under.
Other things that act on it
Enzymes, hormones, genes, and other components with a recorded effect. These are not nutrients, so they do not count toward the arrows above. Each finding names the chapter that recorded it.
How nutrients reach it in more than one step
Chains of two or more recorded steps that end here, grouped by the nutrient they start from. Each step is a separate finding, so a chain is a route a mechanism could take, not proof that it does.

What it does
Every recorded relationship this component is part of, grouped by its role. Plain wording comes first; the technical statement follows.
What acts on it
At the same ascending phytate-P additions, seven-day calcium retention was 31%, 28%, 27%, 26%, 22%, 19%, 14% and 11%; reduction was significant from 100 mg phytate-P in this study.

- experimental_model
- Human dual-radioisotope meal study: 40 subjects, 105 meals
- exposure
- Wheat-roll meals contained 3.1 mg zinc and 266 mg calcium; added sodium phytate supplied 0–250 mg phytate phosphorus.
- limitations
- Phytate-P mass is phosphorus mass, not total phytate mass. Seven-day calcium retention and zinc absorption are distinct endpoints; meal-specific significance levels are not universal thresholds.

- Zinc research collection; topical membership is not evidence of a direct dietary effect. · Zinc
