Food contributions and uncertainty
Values are available for 13 of 13 recorded foods. 1 contribution(s) use an incomplete recipe or comparator. Product identity and portion assumptions still limit accuracy.
The saved portion/recipe scenarios span 2,138–2,177 mg. This is a sensitivity range, not a confidence interval; uncertain food composition and unreported foods can fall outside it.

Role and applicable references
Calcium supports the mineral structure of bones and teeth and participates in muscle, nerve and other cellular functions. For men aged 19–30, the RDA is 1,000 mg/day and the UL is 2,500 mg/day from all sources. An intake above the RDA does not imply additional bone benefit; the UL is a usual-intake safety reference rather than a target. NIH calcium fact sheet
What the latest estimate shows
The saved food estimate is about 2,153 mg. The confirmed whole 907 g yogurt tub supplies about 1,814 mg, using an online listing that still needs confirmation against the actual package. The next largest contributions are much smaller: orange about 60 mg, sardines about 52 mg, chicken about 45 mg and raspberries about 43 mg.
This is a useful example of why food identity matters. These sardines are skinless and boneless. Their user-reported label gives 4% of the calcium Daily Value, converted in the catalog to 52 mg. A generic bone-containing sardine entry would greatly exaggerate calcium from this particular can. The current calculation preserves the matching label instead.
The attention flag is Review, chiefly to verify the yogurt label before treating this relatively high estimate as a stable daily pattern. It does not suggest calcium deficiency. No calcium supplement was reported, and adding one is not justified by this day. Reducing yogurt for appetite or convenience could remain compatible with adequate calcium, but the new portion should be calculated rather than assumed.
Water added to yogurt to make ayran changes the drink's volume, not its total calcium. Drinking the same tub over the day therefore remains the same nutrient quantity. If only part of the tub is consumed, only that part belongs in the log.
Bone and training research: useful, but context matters
In female military recruits, combined calcium/vitamin D reduced stress fractures. The bone-loading investigation develops the intervention, absolute outcomes and limits. Original trial.
Counterevidence to indiscriminate supplementation comes from the Women's Health Initiative: 36,282 postmenopausal women received 1,000 mg calcium plus 400 IU vitamin D or placebo for about seven years. Hip bone density improved slightly, but hip fractures were not significantly reduced in the main analysis, and kidney stones increased. Different populations and baseline intakes explain why these findings should not be collapsed into one universal supplement rule. Jackson et al., 2006
For this pattern, the immediate task is accurate portions and a sustainable source of calcium. Calcium adequacy is one part of bone health; a food table cannot measure bone strength, energy availability or an injury's cause.
