Phosphate is present in many foods popular in the American diet including meat, fish, dairy products, processed foods, and beverages. Phosphate is added to many foods because it acts as an emulsifying agent, prevents clumping, improves texture and taste, and extends shelf-life. The average intake of phosphorus in US adults ranges between 1,000 and 1,500 milligrams per day, well above the RDA of 700 milligrams per day. The UL set for phosphorous is 4,000 milligrams per day for adults and 3,000 milligrams per day for people over age seventy.\r\n\r\n<strong>Table 10.3<\/strong> <em>Dietary Reference Intakes for Phosphorus<\/em>\r\n<div>\r\n<table>\r\n<tbody>\r\n<tr>\r\n<td>Age Group<\/td>\r\n<td>RDA (mg\/day)<\/td>\r\n<td>UL (mg\/day)<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Infants (0\u20136 months)<\/td>\r\n<td>100*<\/td>\r\n<td>\u2013<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Infants (6\u201312 months)<\/td>\r\n<td>275*<\/td>\r\n<td>\u2013<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Children (1\u20133 years)<\/td>\r\n<td>460<\/td>\r\n<td>3,000<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Children (4\u20138 years)<\/td>\r\n<td>500<\/td>\r\n<td>3,000<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Children (9\u201313 years)<\/td>\r\n<td>1,250<\/td>\r\n<td>4,000<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Adolescents (14\u201318 years)<\/td>\r\n<td>1,250<\/td>\r\n<td>4,000<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Adults (19\u201370 years)<\/td>\r\n<td>700<\/td>\r\n<td>4,000<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>Adults (&gt; 70 years)<\/td>\r\n<td>700<\/td>\r\n<td>3,000<\/td>\r\n<\/tr>\r\n<tr>\r\n<td>* denotes Adequate Intake<\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\n<\/div>\r\n<em>Micronutrient Information Center: Phosphorus.
