Your kidneys play an essential role in your overall health. They are responsible for filtering waste and excess fluids from the blood before they are excreted as urine.
Additionally, they help regulate blood pressure, balance electrolytes, and produce hormones that promote healthy bones and red blood cell production. Proper nutrition is crucial for maintaining kidney health and preventing or managing kidney disease.
Limit Sodium Intake
Sodium, or salt, can contribute to high blood pressure, which is a leading cause of kidney disease. To protect your kidneys, limit your sodium intake to no more than 2,300 milligrams per day.
This can be difficult since many processed foods, such as canned soups and frozen meals, are high in sodium. Instead, opt for fresh fruits and vegetables and use herbs and spices to flavor your meals instead of salt.
Aim for a Healthy Weight
Carrying excess weight can put a strain on your kidneys and increase your risk for kidney disease. Aim for a healthy weight by eating a balanced diet and exercising regularly.
If you need to lose weight, a registered dietitian can help develop a personalized plan that is safe and effective.
Get Enough Vitamins and Minerals
Getting enough vitamins and minerals is important for kidney health. Vitamins B6, B12, and folate are necessary for red blood cell production and may help lower levels of homocysteine, an amino acid that can damage blood vessels.
Vitamin D is essential for healthy bones and promotes calcium absorption. Getting enough calcium and phosphorus is also important for bone health. Your healthcare provider may recommend supplements if you are unable to get enough of these vitamins and minerals from your diet alone.
Limit Protein Intake
While protein is an essential nutrient, consuming too much can be harmful to the kidneys. When protein is broken down and metabolized, it produces waste products that your kidneys must filter out.
Eating too much protein can put a strain on your kidneys and increase your risk for kidney disease. However, it is important to note that not all sources of protein are the same. Animal-based proteins, such as meat and dairy, are usually higher in protein than plant-based sources, such as beans and legumes.

Manage Blood Sugar
High blood sugar can damage blood vessels in the kidneys and increase your risk for kidney disease. If you have diabetes, it is important to manage your blood sugar levels to prevent complications.
This may include monitoring your blood sugar regularly, taking medications as prescribed, and following a healthy diet and exercise plan. If you are struggling to manage your blood sugar, speak with your healthcare provider or a registered dietitian.
Drink Plenty of Water
Staying hydrated is important for kidney health. Drinking enough water can help flush out waste products and excess fluids from your body. Aim to drink at least 8 cups of water per day, or more if you are physically active or live in a hot climate.
If you have kidney disease or are on dialysis, speak with your healthcare provider about how much water is safe for you to drink.
Avoid Tobacco and Alcohol
Smoking and drinking too much alcohol can damage your kidneys and increase your risk for kidney disease. If you smoke or drink, quit or cut back as much as possible.
If you need help quitting smoking or reducing your alcohol intake, speak with your healthcare provider or a counselor.
Conclusion
Proper nutrition is essential for maintaining kidney health.
By following a balanced diet that includes plenty of fruits and vegetables, limiting sodium and protein intake, managing blood sugar, staying hydrated, and avoiding tobacco and alcohol, you can support your kidney health and reduce your risk for kidney disease. If you have concerns about your kidney health or are at risk for kidney disease, speak with your healthcare provider or a registered dietitian.
