Phosphate Food Additives
Phosphate Food Additives are a form of phosphorus, a mineral that supports bone health. But phosphorus-containing additives, such as phosphoric acid and disodium phosphate, are found in a variety of processed foods-including soda, baked goods, dairy products, and fast food. Phosphorus from additives is more readily absorbed than when it occurs naturally in food.
What's the concern? High phosphorus intake is hazardous for people with kidney disease or those at risk for it. "If kidney function is impaired, getting too much phosphorus puts extra strain on the kidneys to try to excrete it," Hunnes says. But even those with healthy kidneys should be cautious about eating too many foods with phosphate additives. Too much phosphorus can bind to calcium, pulling it from bones and leaving them brittle. And researchers have found a link between high phosphate levels and increased cardiovascular risk. A 2013 study in the U.K. of more than 700,000 people found that those with normal kidney function but high phosphorus levels had a 36 percent increased risk of a cardiovascular event (such as a stroke or heart attack) over those with normal phosphorus levels.
Sodas and baked goods may have phosphorus-containing additives, which have been linked to kidney and heart problems.

After publication of this article on July 20, 2020, CR was contacted by Hayashibara, makers of trehalose, who noted that the conclusions drawn from the study we cited were focused on animals and pointed to research in the journals EBioMedicine and Open Forum Infectious Diseases that the company says supports trehalose's safety. CR reviewed these studies and does not believe they rule out a relationship between C.diff and trehalose.
