Foods to avoid for better kidney health

Managing kidney disease requires careful attention to diet. Certain foods can worsen kidney function or cause complications. Here are 10 foods to avoid for better kidney health and overall well-being.

Avocados

Avocados are rich in heart-healthy fats, fibre, and antioxidants. However, due to their high potassium content of about 690 mg per avocado, they should be limited or avoided in a kidney disease diet.

Dairy products

Full-fat dairy products like cheese, butter, and cream can strain the kidneys and raise cholesterol levels, which may worsen kidney function and increase cardiovascular risks.

Processed meats

These meats are high in sodium, phosphorus additives, and unhealthy fats, which can elevate blood pressure, harm kidney function, and increase the risk of cardiovascular issues in kidney disease.

Tomatoes

Tomatoes are high in potassium and may not suit a renal diet. One cup of tomato sauce (245 g) contains 728 mg of potassium, making it less ideal for kidney disease management.

Oranges

Oranges and orange juice, though high in vitamin C, are also high in potassium. A large orange contains 333 mg, and one cup of juice has 458 mg, making them unsuitable for kidney disease.

Red meat

Red meat contains high levels of protein and phosphorus, which can overwhelm the kidneys, especially in larger amounts, potentially leading to further kidney damage and complications in those with kidney disease.

Canned foods

Many canned vegetables and beans contain high sodium to preserve freshness, which can raise blood pressure, cause fluid retention, and put additional stress on the kidneys over time.

Refined sugars

Foods rich in refined sugars, like sodas and sweets, contribute to weight gain, high blood sugar, and kidney strain, potentially worsening kidney disease and increasing the risk of other complications.

Alcohol

Excessive alcohol consumption can negatively affect kidney function, raise blood pressure, dehydrate the body, and contribute to complications that accelerate the progression of kidney disease.
