Low grade, controversial or vague ingredient we usually recommend avoiding

Phosphoric Acid in dog food

Phosphoric acid (E338) is a clear, colourless liquid that is added to foods primarily as an acidifier but is also used effectively as a flavouring, emulsifier and to prevent discolouration. It is best known as an additive in cola drinks.

Studies have linked phosphoric acid to reduced bone density in humans making it a fairly controversial ingredient for both people and dogs. Although more work is necessary to confirm the link, we would recommend playing it safe in the meantime and steering clear of foods with high levels of phosphoric acid.
