On an acid-ash diet to acidify urine, which beverage must be restricted?

• A. Milk
• B. Apple juice
• C. Lemonade
• D. Water

Answer: (A)

The main idea is that an acid-ash diet aims to make urine more acidic by limiting foods that leave alkaline ash in the body. Milk is a dairy product that tends to leave alkaline residues after metabolism, which can raise urine pH and counteract acidity. By restricting milk, you help maintain a more acidic urine environment, which is why it’s the beverage to limit in this context. Water is neutral and doesn’t significantly shift urine acidity, and many fruit juices are not the primary contributors to alkaline ash in this dietary pattern, so they don’t carry the same restriction.
