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?
A. Milk, apples, tomatoes, and corn.
B. Eggs, spinach, dried peas, and gravy.
C. Salmon, chicken, caviar, and asparagus
D. Grapes, corn, cereals, and liver.
Correct Answer: A. Milk, apples, tomatoes, and corn.
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. Food 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.
Option B: The diet centers on the acid-ash hypothesis, which essentially says consuming a diet rich in fruits and vegetables and with moderate amounts of protein promotes an alkaline load and a healthier lifestyle. Gravy is high in purine.
Option C: The alkaline diet emphasizes consuming alkaline foods in an attempt to make the body’s pH more alkaline. That said, it is impossible to change the body’s pH through diet. Indeed, the body’s pH actually varies based on the region. Poultry is acidic and rich in purine.
Option D: The diet is organized around the pH of individual foods. Some versions are less strict, meaning they may allow grains for their health benefits despite their slightly acidic pH. The alkaline diet’s emphasis on fruit and vegetables over processed foods overlaps considerably with the paleo diet, which is meant to mimic the dietary habits of our hunter-and-gatherer ancestors.
