An acid ash is formed when the metabolism of certain foods results in the production of acidic residues in the body. Foods that are high in protein, phosphorus, and sulfur tend to generate an acid ash. Corn and cranberries fall into this category because they contain compounds that, when metabolized, create an acidic environment.

Corn is a cereal grain that contributes carbohydrates but also has a mixed composition that leans toward creating acid residues. Cranberries are known for their acidity and are often associated with promoting an acidic urinary pH. Together, they create an acid ash effect upon metabolism.

The other food categories listed do not primarily lead to acid ash formation. Milk, for example, contains a balance of nutrients that can create a more neutral pH rather than acidic, while many vegetables and fruits generally produce alkaline residues despite containing some acidic components. Thus, the combination of corn and cranberries is specifically noted for its potential to produce an acid ash in the body.
