What should be avoided in the diet of elderly patients with nephrotic syndrome?
Disease description:
My father's health has not been very good in recent years, and he has been feeling unwell again recently. After going to the hospital for a checkup, he was diagnosed with nephrotic syndrome. I would like to ask what kinds of food are generally recommended to help recover from this condition more quickly?

Foods to avoid or limit for elderly patients with nephrotic syndrome:
1. High-sodium foods: Reducing sodium intake helps control edema and hypertension; avoid pickled foods, preserved foods, processed meats, fast food, and takeout meals.
2. High-protein foods: Excessive protein intake can increase the burden on the kidneys. Limit intake of red meat, poultry, fish, soy products, and dairy products, and follow medical advice regarding low-protein diets.
3. High-potassium foods: When the kidneys' ability to excrete potassium is reduced, avoid high-potassium foods such as bananas, potatoes, oranges, tomatoes, nuts, and seeds.
4. High-phosphorus foods: Limit phosphorus-rich foods such as dairy products, nuts, whole grains, chocolate, and carbonated beverages to prevent elevated blood phosphorus levels.
5. Irritating foods: Spicy, greasy, smoked foods, and those high in caffeine may increase kidney burden or affect digestion.
