Phosphorus, which constitutes hydroxyapatite with calcium, is a important component of bone. It is considered that there is no need to worry about the lack of phosphorus in the ordinary dietary habits, because a various of foods contain phosphorus. Recently, an excess intake of phosphorus is considered a problem, because phosphorus is frequently used as a food additive. It has been reported that parathyroid hormone and bone resorption markers are increased in case of low calcium/phosphorus intake ratio. In the Dietary reference intakes for Japanese, 2010, shows 3,000 mg/day as a tolerable upper intake level of phosphorus. Some issues such as the intake ratio of calcium to phosphorus and an effect of organic phosphorus and inorganic phosphorus remain to be solved.
磷与钙构成羟基磷灰石,是骨骼的重要组成部分。人们认为,在普通饮食习惯下无需担心磷缺乏问题,因为各种食物都含有磷。最近,过量摄入磷被视为一个问题,因为磷经常被用作食品添加剂。据报道,钙/磷摄入比例低时,甲状旁腺激素和骨吸收标志物会增加。《2010年日本人膳食参考摄入量》显示,磷的可耐受最高摄入量为每日3000毫克。钙磷摄入比例以及有机磷和无机磷的影响等一些问题仍有待解决。
