For every 100g of asparagus there is 50.54 mg of phosphorus which is a fairly significant amount. Phosphorus plays a number of important roles in the body, such as making sure that the bones stay strong and that cells grow at a healthy rate. It also plays a vital role in the development of our teeth over time. Almost all foods contain phosphorus so it is impossible to eliminate it from your diet altogether, though some foods like asparagus have more of it than others.
A healthy amount of phosphors in the body helps it to properly and efficiently utilize fats and carbohydrates which we ingest on a daily basis. If you are looking into increase the amount of phosphorus in your diet it will be important to know which foods you should eat, including those in the protein group like milk and meat. While it is true that a vast majority of fruits and vegetables do not contain a lot of phosphorus, asparagus is one of the few exceptions.
