Although it has always been stated that foods high in sodium are harmful to the kidneys, there are other foods that are also damaging them and you probably consume them daily. The problem is that they increase their workload and promote deterioration.

Nephrology specialists warn about two groups that are usually part of the daily diet of millions of people: foods rich in potassium and products with high levels of added sugars.

The two foods that damage your kidneys without realizing it

1. Potatoes and other foods rich in potassium

The potato is one of the most consumed foods in the world. Its popularity is due to the fact that it provides energy, fiber, vitamin C and other important nutrients. However, it also contains considerable amounts of potassium.

In people with healthy kidneys, this mineral is usually eliminated without difficulty through urine. The problem appears when there is chronic kidney disease (CKD), since the filtration capacity decreases and potassium can accumulate in the blood.

This condition, known as hyperkalemia, can cause muscle weakness, changes in heart rhythm and even serious complications if it is not properly controlled, notes the Medline Plus medical portal.

For that reason, experts often recommend that CKD patients carefully monitor the amount of potassium they consume.

In addition to potatoes, other foods rich in this mineral are avocado, banana, kiwi, melon, papaya, spinach, pumpkin, tomato, broccoli, beans, some lean meats and fish such as sardines and cod.

The key is to adapt the diet to the medical conditions of each patient, so it does not mean that you should eliminate these options that are really very nutritious.

2. The risk of added sugars

The second group pointed out by experts are added sugars, especially those present in soft drinks, energy drinks, industrialized juices and numerous ultra-processed products.

Various research has linked frequent consumption of these drinks with a greater risk of developing obesity, insulin resistance, high blood pressure and type 2 diabetes.

Precisely, these last two diseases are among the main causes of kidney damage throughout the world.

In addition, some epidemiological studies have observed that those who regularly consume sugary drinks are more likely to suffer a progressive deterioration in kidney function in the long term.

Doctors insist that the solution is not to abandon these foods, but to maintain a balanced consumption, in addition to significantly reducing added sugars and ultra-processed foods.

Finally, another essential aspect is to stay well hydrated. Drinking enough water helps the kidneys eliminate waste and facilitates the proper functioning of the urinary system.
