It could be in your food, but it’s under a name you probably don’t recognize. Is disodium phosphate dangerous?
What is it?
Disodium phosphate is a food additive. It’s “generally recognized as safe” (GRAS) by the U.S. Food and Drug Administration (FDA).
Phosphates like disodium phosphate are derived from the element phosphorus. They’re used to enhance food characteristics like nutritional value and cooking performance. Disodium phosphate is used in packaged foods, including macaroni and pastas. It’s also used in some cheeses as an emulsifier. You can also find it in meat products, canned sauces, Jell-O, evaporated milk, and some chocolate.
Originally derived from animal bones and urine, phosphorus is now extracted from phosphate rock. It’s purified and put through chemical reactions.
Is it safe?
When it comes to food additives, it’s completely normal to wonder about safety. The FDA’s stance isn’t completely reassuring for some people.
The Environmental Working Group (EWG) says there is a “fair” amount of data available on this phosphate. The EWG says that the additive can be considered safe. It’s not considered to be an environmental toxin or potentially harmful to humans. Disodium phosphate is not bioaccumulative (where it accumulates within your body over time). It’s also classified as a “low human health priority” under Canadian law.
In 2012, a study was published declaring phosphates in general to be hazardous. The researchers suggested that all foods containing phosphates should be labeled as dangerous to public health. According to their research, accumulating phosphates in the body can cause organ calcification in people with renal failure, and even in people without kidney problems.
But the International Food Additives Council states that inorganic phosphates have a long history of safe use in food and that additional studies have proven their safety. That being said, foods containing disodium phosphate are often packaged and heavily processed, so they’re not the healthiest choices to begin with.
How to avoid it
If you’re leery of disodium phosphate despite assurances of its safety, you can simply keep it out of your diet. However, identifying it may be difficult.
In most cases, all you need to do is check the ingredients list on food packaging to tell if an item contains disodium phosphate or not. However, phosphates are also used in the meat industry to prevent spoilage, and meat packages don’t typically mention this.
Avoiding packaged and processed foods is one way around disodium phosphate. This will benefit your overall health as well. Purchasing locally produced meats is another way to avoid disodium phosphate.
