Phosphorous deficiencies are extremely rare and virtually unheard of no matter what you eat so even if you lose some phosphorous due to some enzymes inhibiting the absorption of phosphorous you will still have plenty of phosphorous left.

If you are worried about not getting enough phosphorous from a normal diet perhaps you could take a phosphorous supplement every day.

Generally just eat enough protein. If you need more than that, you have a very strange disorder.
