Eating & Nutrition for Good Kidney Health

Maintaining kidney health involves paying close attention to your diet, so that you consume the right amounts of essential nutrients.

Here's a breakdown of key nutrients and their recommended daily intakes —

Protein - It is essential for building and repairing tissues, but too much can strain the kidneys. A healthy adult should consume protein around 0.8–1 gram per kilogram of body weight daily. Lean meats, fish, eggs, beans, and low-fat dairy are great sources of high-quality protein.
Sodium - Sodium affects blood pressure and too much can put stress on the kidneys. To maintain good kidney health, it’s advisable to limit intake to less than 2,300 mg per day (about a teaspoon of salt). Choosing fresh, whole foods over processed ones can help reduce sodium intake naturally. Staying hydrated also helps flush out excess sodium from the body.
Potassium - It plays a key role in fluid balance and muscle function, directly impacting kidney health. The recommended daily intake is around 2,600 mg for women and 3,400 mg for men. Foods like bananas, oranges, spinach and beans provide a natural source of potassium. Keeping levels balanced prevents kidney strain and supports overall heart health.
Magnesium - It helps in regulating blood pressure and supports muscle and nerve function. Adults need 310-420 mg per day, depending on age and gender. Nuts, seeds, whole grains and leafy greens are excellent sources.
Phosphorus– It is necessary for energy production and strong bones but must be balanced carefully. The recommended daily intake of magnesium is 700 mg per day for adults. Good sources include dairy, meat, fish, nuts and whole grains. Excess phosphorus, especially from processed foods, can harm kidney function over time.
