Final answer:
The American Kidney Fund advises moderation with high-protein diets due to the risk of added strain on the kidneys. Low-protein, low-nitrogen, and low-sodium diets, along with adequate hydration, are recommended, especially for those with potential kidney issues.
Step-by-step explanation:
The American Kidney Fund recommends caution when it comes to high-protein diets, particularly for individuals with existing kidney problems. Consuming too much protein can put strain on the kidneys, leading to potential issues such as kidney stones and gout. Conversely, proteins are essential for bodily functions, and high-protein foods should still make up about a quarter of each meal, consisting options like fish, chicken, dairy products, legumes, or nuts.
However, adherence to a diet that reduces excretory load on the kidneys is advisable for prevention. This includes a diet low in protein, nitrogen, and sodium. Moreover, maintaining sufficient hydration, approximately enough to produce 2 to 2.5 liters of urine per day, and restricting oxalate-rich foods which could influence kidney stone formation, are recommended as preventive measures.
