E450 — Diphosphates
E450 (Diphosphates), a emulsifier, is rated "avoid": worth avoiding. A processed-cheese and meat-product stabiliser that smooths texture and binds water. Heavy daily intake of added phosphates strains kidneys and accelerates vascular calcification.
What is Diphosphates?
An inorganic phosphate salt used in processed cheese, deli meats, frozen seafood, instant puddings, and baking powder. Smooths texture, binds water, and extends shelf life.
What does it do to the body?
Added phosphates absorb much more efficiently than the phosphate naturally present in food. Heavy daily intake of processed foods raises blood phosphate, which strains the kidneys and accelerates vascular calcification. Healthy adults handle moderate amounts; people with kidney disease should limit intake.
What regulators say
EFSA set a group acceptable daily intake of 40 mg phosphorus per kg of body weight per day in 2019 and warned that average European intake already approaches this limit. The FDA approves phosphates as GRAS.
Risk rating: Avoid
Known or suspected to cause harm: a substance EFSA or another regulator has flagged, or one restricted in some jurisdictions. Best kept out of a regular diet.
