Enjoy these phosphorus rich foods for stronger bones, muscles and heart health Phosphorus is an essential mineral with an impressive range of functions, so eating a range of phosphorus rich foods is incredibly important for overall health. “It’s found in your body and has an important role in the formation of strong bones and teeth,” says registered dietitian Dr Melissa Prest, a National Spokesperson for the Academy of Nutrition and Dietetics (opens in new tab). Phosphorus rich foods include dairy, poultry, legumes, nuts, seeds and red meat. You can also take it in supplement form. But why bother? Phosphorus is a key element of cell membranes and it helps to activate enzymes, keeping blood pH within a normal range. This is one of the most important physiological functions of homeostasis (the body’s steady state). We need healthy blood pH levels to maintain our respiratory and circulatory systems, as they work together to ensure nutrients and oxygen-rich blood reach our cells. The kidneys, bones and intestines work hard to regulate phosphorus levels in the body. If too little or too much is absorbed, several things happen to preserve stores and maintain equilibrium: the kidneys excrete less phosphorus in urine, the digestive tract gets more efficient at absorbing it and the bones release their stores of phosphorus into the blood. The opposite process happens in these organs if the body has enough phosphorus stores. How much phosphorus do you need? Many foods naturally contain phosphorus, known as ‘organic phosphorus’. The main sources are dairy, red meat, poultry, seafood, legumes and nuts. ‘Inorganic phosphorus’, on the other hand, is a processed form added to foods to preserve color, moisture and texture. It’s mainly in fast food, deli meat, sodas and other processed foods. “The recommended amount for adults to consume in a day is 700 milligrams. We consume phosphorus naturally occurring in food, and foods that have phosphorus added to them,” says Dr Prest. “Phosphorus additives enhance flavors, allow for shelf-stability and can make foods creamier and easier to melt,” says Dr Prest. “But we don’t absorb 100% of the phosphorus naturally found in foods; we typically absorb anywhere from 30 to 60%, with plant sources being the least absorbed and animal sources being the best. “However, we absorb 90 to 100% of phosphorus when it is in additive form. Consuming too much phosphorus may be a concern for people with certain health conditions such as chronic kidney disease, so it is best to meet our phosphorus needs by eating phosphorus rich foods.” The best phosphorus rich foods Want to know some of the best phosphorus rich foods? Dr Prest reveals 11 sources of this essential mineral, and how you can incorporate it into your diet. Cottage cheese This has 358 mg of phosphorus (49% of recommended daily intake) in a 1 cup serving. Cottage cheese is great as a snack or protein option for the main meal.
