Substitution of Cerelose (glucose monohydrate) for complex carbohydrate (whole wheat flour) does not alter plasma calcium levels in vitamin D-deficient rats, contrary to a previous report. It is suspected that whole wheat flour may contain traces of vitamin D that result in a slower rate of depletion than found with Cerelose diets. Vitamin D-deficient rats showing low plasma 1,25-dihydroxyvitamin D3 levels and no detectable 25-hydroxyvitamin D3 levels in their blood show a hypocalcemia (5.6 mg/dl) and normal phosphatemia whether fed whole wheat or Cerelose diets.
与之前的一份报告相反，用无水葡萄糖替代复合碳水化合物（全麦面粉）并不会改变维生素D缺乏大鼠的血浆钙水平。据推测，全麦面粉可能含有微量的维生素D，这导致其耗竭速度比食用无水葡萄糖饮食时要慢。血浆1,25 - 二羟维生素D3水平低且血液中检测不到25 - 羟维生素D3水平的维生素D缺乏大鼠，无论喂食全麦面粉还是无水葡萄糖饮食，均表现为低钙血症（5.6毫克/分升）和正常血磷水平。
