Needless to say, the kidneys play an important role in our body – they remove excess toxins and fluids from the body, maintain balanced blood pressure and alkaline-acid balance. That is why you need to take good care of these small organs and keep them healthy. Unfortunately, there are foods that, although very tasty, can affect their normal functioning if eaten too often or in large quantities.
Here are the most popular foods that can seriously damage your kidneys:
Although avocados are popular and loved for their various nutritional qualities, excessive consumption can be dangerous for your kidneys due to high potassium levels. Of course, the body still needs this mineral, but if the blood is saturated, muscle spasms and irregular heartbeat can occur.
Eating too much meat can cause kidney problems, as animal proteins are very difficult to digest, which makes eliminating waste products a burden on the kidneys. The development of kidney stones can also leads by diet rich in animal protein. Meat has large amounts of purines, which stimulate the production of uric acid, which is one of the common causes of kidney stones.
You could eat more vegetables and nuts instead and still get the protein your body needs.
A healthy diet should include a maximum of 2300 mg of sodium per day (about one teaspoon of salt). If you eat too much salt, your kidneys need to work harder to eliminate excess sodium so that they can begin to retain water, which can lead to high blood pressure.
To keep your kidneys healthy, you can add spices and herbs to your diet instead of abusing salt. You can also reduce the consumption of processed and packaged foods, such as canned soups or vegetables, frozen pizza and salad dressings, as they usually contain a lot of salt.
If you suspect that you have kidney problems, good nutrition and proper diet are essential for maintaining good health. And that means limiting the consumption of certain foods, such as bananas, because they have very high levels of potassium, which can be harmful to people whose kidneys are not functioning properly.
One adult should take 3500-700 mg of potassium per day from food, and a medium-sized banana (150 g) contains 537 mg. But if you suffer from kidney disease, your potassium intake should be lower, as your body may not be able to filter the excess, which can lead to serious health problems.
5. Dairy products
Although dairy products are rich in vitamins and nutrients, too much milk, yogurt and cheese can do more harm than good. And this can happen because of the large amount of phosphorus contained in these foods, which can “stress” your kidneys.
In addition, if your kidneys do not function very well, they will not be able to remove the extra phosphorus from your blood and this can lead to an increased risk of fractures and thin and weak bones over time.
6. Wholemeal bread
Wholemeal bread is healthy and filling, but if eaten in large quantities and especially by people with kidney problems, it can damage the kidneys even more. The reason is the high amounts of phosphorus and potassium contained in this type of bread. One slice of wholemeal bread contains 70 mg of potassium and 57 mg of phosphorus, compared to one slice of white bread, which contains only 25 mg of each.
7. Oranges and orange juice
Oranges and orange juice are low in calories and rich in vitamin C, but they also have high levels of potassium. One medium orange provides 240 mg of potassium, and one glass of orange juice can contain about 470 mg.
Given these numbers, the consumption of oranges and orange juice should be limited, especially when you do not have a fully functioning kidney. If they cannot eliminate excess potassium from the blood, it can be very dangerous for your body.
