IMPORTANT ANOUNCEMENT ABOUT PHOSPHORUS! Although the law does not require phosphorus amounts to be listed on food labels, many manufacturers do list a per centage of the recommended daily value. In the past the daily phosphorus intake recommendation has been 1000 mg for adults, especially senior adults and 700 for CKD patients. In 2021 the RDA will change to 1250 mg recommended daily. On food labels indicating a per centage, find the percent in mg of the new recommended value of 1250 even if you have CKD as that will give a more accurate phosphorus amount.
