Because a client's renal stone was found to be composed of uric acid, a low-purine, alkaline-ash diet was ordered. Incorporation of which of the following food items into the home diet would indicate that the client understands the necessary diet modifications?
1. Milk, apples, tomatoes, and corn.
2. Eggs, spinach, dried peas, and gravy.
3. Salmon, chicken, caviar, and asparagus.
4. Grapes, corn, cereals, and liver.
Because a high-purine diet contributes to the formation of uric acid, a low-purine diet is advocated. An alkaline-ash diet is also advocated because uric acid crystals are more likely to develop in acid urine. Foods that may be eaten as desired in a low-purine diet include milk, all fruits, tomatoes, cereals, and corn. Foods allowed on an alkaline-ash diet include milk, fruits (except cranberries, plums, and prunes), and vegetables (especially legumes and green vegetables). Gravy, chicken, and liver are high in purine.
