pPeople suffering from advanced kidney disease are taught to avoid foods that are naturally high in phosphorus, which is difficult for compromised kidneys to get filter. But researchers now warn that a fair amount of processed and fast food actually contains phosphorus additives, which can be just as harmful./p pHigh blood levels of phosphorus can lead to heart disease, bone disease, and even death for patients with advanced kidney disease. But it has become an increasingly common practice to include phosphate salts to processed foods./p pThese additives are used to enhance flavor and shelf life, and it is very hard for consumers to know whether or not these additives are present in products.
