Many phosphorus-rich foods are found in everyday diets, particularly among protein-rich options. Meat, poultry, and fish are excellent examples, with chicken and turkey providing approximately 194-196 mg of phosphorus per 3-ounce serving, covering nearly 16% of the Daily Value (DV). Dairy products also contribute notably; for instance, skim milk and Romano cheese offer 17%-21% of the DV per serving. Legumes like beans and lentils can deliver at least 250 mg per cup, serving up over 28% of the DV. Whole grains, particularly spelt and oats, present varying levels of phosphorus too, typically between 8%-23% per cooked cup.
Phosphorus in Dietary Supplements
For those who may struggle to meet their daily phosphorus needs through diet alone, phosphorus supplements provide a viable alternative. Typically available as standalone products or included in multivitamins, these supplements are often composed of phosphate salts, boasting absorption rates of around 70%. This makes them an effective option for individuals looking to increase their phosphorus intake efficiently. While most adults can achieve adequate levels through well-rounded diets, supplements remain a practical choice for specific needs.
Processed Foods and Additives
Many processed foods phosphorus can significantly impact overall phosphorus intake. Common items such as fast foods, deli meats, and canned beverages often contain phosphorus additives, which contribute around 155 mg of phosphorus per day and account for as much as 30% of phosphorus consumption in the U.S. diet.
