Which foods are commonly restricted on a renal diet?

• A. Red meat and shellfish
• B. Potatoes and citrus fruit
• C. Cookies and cake
• D. Lean meat and chicken

Answer: (B)

Renal diets focus on balancing minerals that the kidneys handle poorly, especially potassium. When kidney function is reduced, potassium can build up in the blood and lead to dangerous heart rhythms, so foods high in potassium are commonly restricted. Potatoes and citrus fruits are well-known high-potassium foods, making them a classic part of the restricted list. Other foods may be limited for different reasons (phosphorus or protein content, sugars, fats), but they aren’t as universally restricted as potassium-rich items. Red meat and shellfish can be limited for phosphorus and protein concerns, cookies and cake for sugar and fat, and lean meat and chicken are generally acceptable in controlled portions for protein. Thus, potatoes and citrus fruits best illustrate the common renal-diet restriction.
