Kidneys play an important role in keeping our body healthy. They filter out waste products from the blood and help regulate blood pressure, electrolyte balance, and red blood cell production. Hence, it becomes crucial to keep them healthy.

One way to do that is by following a healthy diet. In this article, we will discuss some dietary tips for healthier kidneys.

1. Reduce Sodium Intake

High sodium intake can increase blood pressure and damage the kidneys. It is, therefore, essential to limit the amount of sodium in your diet. The American Heart Association recommends consuming not more than 2,300 milligrams (mg) of sodium per day.

This is equivalent to one teaspoon of salt per day. You can reduce sodium intake by:.

• Avoiding processed and packaged foods as they contain high amounts of sodium.
• Choosing fresh fruits and vegetables over canned ones. If you opt for canned fruits and vegetables, choose low-sodium or no-salt-added varieties.
• Flavoring your food with herbs and spices, instead of salt.

2. Limit Phosphorus Intake

Phosphorus is a mineral found in many foods like dairy products, fish, poultry, and whole grains. If you have kidney disease, your kidneys may not be able to remove excess phosphorus from the body.

Hence, it is crucial to limit phosphorus intake to prevent kidney damage. The recommended daily intake of phosphorus for healthy adults is about 700 mg to 1000 mg per day. You can limit phosphorus intake by:.

• Avoiding high-phosphate foods like dairy products, processed foods, and cola drinks.
• Choosing low-phosphate foods like fresh fruits and vegetables.
• Taking your phosphate binders as prescribed by your doctor as they can help reduce the amount of phosphorus absorbed by the body.

3. Monitor Protein Intake

Protein is an essential nutrient for our body. However, consuming too much protein can strain the kidneys and worsen kidney disease. If you have kidney disease, your doctor may recommend limiting protein intake.

The recommended daily intake of protein for people with kidney disease is about 0.8 grams per kilogram of body weight. You can monitor protein intake by:.

• Choosing plant-based sources of protein like legumes, tofu, and nuts instead of meat.
• Opting for low-protein foods like fruits and vegetables.
• Consulting a dietitian to create a meal plan that meets your nutritional needs and helps you manage kidney disease.

4. Drink Plenty of Water

Drinking enough water is essential for kidney health as it helps flush out toxins from the body. If you don’t drink enough water, the toxins can accumulate and lead to kidney damage.

The recommended daily intake of water for healthy adults is about 8-10 glasses per day. You can also calculate your water intake by dividing your body weight in half and drinking that many ounces of water per day. You can drink:.

Alcohol can damage your kidneys and worsen existing kidney disease. Hence, it is essential to avoid or limit alcohol consumption.

Excessive alcohol consumption can also increase blood pressure and lead to dehydration, which can further worsen kidney function.

9. Quit Smoking

Smoking is not only harmful to our lungs but also to our kidneys. It can damage the blood vessels in the kidneys and worsen kidney disease. Hence, it is essential to quit smoking to keep your kidneys healthy.

10. Consult a Dietitian

Consulting a dietitian can help you create a meal plan that meets your nutritional needs and helps you manage kidney disease. A dietitian can also help you monitor your sodium, phosphorus, protein, and fluid intake and suggest changes accordingly.

Conclusion

Eating a healthy, balanced diet is essential for any individual’s overall health and well-being. For individuals with kidney disease, following a kidney-friendly diet is crucial for maintaining kidney function and preventing further damage.

All individuals should work with their healthcare providers and dietitian to develop a dietary plan that is tailored to their specific needs.
