7 common foods that could harm your kidneys if you eat them daily

Diet plays a fundamental role in the health of the kidneys, organs responsible for filtering waste, regulating fluids, and maintaining the body's chemical balance. However, certain foods that are part of our daily diet can silently impair their function, without presenting obvious symptoms until the damage is already advanced.

Although many people focus on taking care of their heart or digestion, the kidneys are often forgotten , and it is precisely this lack of attention that makes it easy for certain eating habits to go unnoticed as risk factors.

Below are some commonly consumed products that, if consumed in excess or regularly, could contribute to impaired kidney function.

1.- Processed meats

Cured meats such as ham, sausage, bacon, and mortadella contain high levels of sodium and chemical preservatives like nitrates, which raise blood pressure and strain kidney function. Frequent consumption of these foods can increase the risk of chronic kidney disease.

2.- Ultra-processed foods

Cookies, snacks, instant soups, sugary cereals, and fast food are loaded with sodium, added phosphorus, and unhealthy fats. These ingredients not only affect blood pressure but can also accelerate kidney decline if not moderated.

3.- Sugary drinks and soft drinks

Daily consumption of sugary beverages, such as soft drinks and processed juices, is linked to an increased risk of type 2 diabetes, one of the leading causes of kidney failure. Furthermore, the added phosphates in some beverages can disrupt the body's mineral balance.

4.- Excess salt

Sodium, present in large amounts in processed foods and when salt is added to meals, can cause fluid retention and increase blood pressure. Over time, this overloads the kidneys and makes them more vulnerable to disease.

5.- Canned products

Although convenient and affordable, many canned foods contain high levels of salt as a preservative. Even seemingly healthy options, such as canned tuna, vegetables, or legumes, can provide more sodium than recommended if not drained and rinsed before consumption.

6.- Artificial sweeteners

While popular among those looking to cut down on sugar, some studies suggest that long-term consumption of artificial sweeteners may negatively impact kidney function, especially in people predisposed to metabolic diseases.
