Avocados are a nutritional powerhouse, rich in healthy fats, fibre, vitamins, and minerals. Their monounsaturated fats promote heart health and can lower bad cholesterol levels. They’re also a good source of potassium, which promotes healthy blood pressure levels. Anyone looking to improve their overall health, especially those seeking heart and weight management benefits, should include avocados in their diet. While avocados may aid in several health problems, people with kidney problems should avoid avocados. Read on to know if eating avocado for kidneys is good or not!

Should you eat avocado for kidneys?

Avocados are incredibly nutritious but they can pose risks for those with kidney disease or related problems. This is primarily due to their high potassium content. “Healthy kidneys regulate potassium levels in the body, but when kidney function is compromised, potassium can accumulate in the blood, leading to a condition called hyperkalemia,” says dietitian Komal Malik. The National Kidney Foundation reports that hyperkalemia frequency is as high as 40-50 percent in people with chronic kidney disease. In fact, it has been found that having too much potassium in your blood can indeed pose a significant risk to health.

For people with kidney disease, consuming foods high in potassium, like avocados, can further elevate potassium levels in the blood, potentially causing heart rhythm abnormalities, muscle weakness, or even cardiac arrest in severe cases. According to the American Kidney Fund, hyperkalemia can even cause a heart attack or death! Unfortunately, many people with hyperkalemia may not experience symptoms until significant heart health issues develop.

5 other foods to avoid if you are at risk of kidney diseases

1. Bananas

High in potassium, bananas can elevate potassium levels in the blood, potentially worsening the symptoms of kidney disease.

2. Oranges

Another source of high potassium, oranges and their juice should be limited or avoided by those with kidney issues.

3. Processed meats

Bacon, sausage, deli meats, and other processed meats are high in sodium and phosphorus, which can strain the kidneys and worsen kidney function.

4. Canned soups and packaged meals

These often contain high levels of sodium, which can contribute to high blood pressure and fluid retention, putting additional stress on the kidneys.

5. Dairy products

Milk, cheese, and yoghurt are high in phosphorus and potassium, so individuals with kidney disease should consume them in moderation or choose low-phosphorus and low-potassium alternatives.

4. Blueberries
