No comment on what foods have both calcium and vitamin D. Makes me think that this study was funded by companies the produce Calcium and Vitamin D supplements, either that or just a shoddy bit of reporting.
Went and skimmed through the published study, looking for the amount of vitamin D dosage. Study results were based on 10ug/day of D, along with calcium supplement. That’s only 400 IU of vitamin D.
Many experts in this area of research advise up to 5000 IU daily, to avoid deficiency. At this purported optimum vitamin D dosage, the body’s usage of calcium is optimized, too, so a calcium supplement should not be needed. I’d be wary of taking calcium along with high vitamin D supplements.
