Diet and drinking habits play a significant role in whether the kidneys are functioning well, or their performance decreases – as in the case of millions of Germans. FOCUS Online spoke with an expert, such as kidney healthy diet looks like.
The eating habits have changed in the last few years, that’s a fact. Only a fifth of the people living in Germany will daily cook itself for a meal. Snacks and Fast Food far outweigh the society for consumer research GfK.
In addition, movement could compensate for this nutritional deficiency is something missing. With fatal consequences for the health: “Diabetes and high blood pressure and this also affects the kidneys,” explains Clemens Cohen, chief physician of the clinic for kidney-, high-pressure and rheumatic disorders in the Munich hospital Harlaching.
Because all blood vessels and heart harm, also goes to the kidneys. The kidneys are the brain is the best perfused Organ. In the fine vessels of the kidney the smallest deposits have significant consequences. The capacity of the filtering organs is reduced.
“One in Ten has an impaired kidney function,” notes Cohen, who conducts research in the field of Nephrology. The kidneys can no longer filter harmful substances from the blood and urinary discharge.
Kidneys are not warn through pain
The Affected know about it, usually nothing, because the kidneys are not suffer quietly – comparable to the liver , it no longer hurt to do so, even if the function is optimal. With the exception of kidney stones trigger severe pain.
Renal function disorders, in contrast, lead to General symptoms, if your function has already declined sharply and even, perhaps, a dialysis is necessary. According to a study, the chronic renal failure has increased in recent years as strong as any other disease.
Connection diet and kidney function
The Western life style with foods that provide many calories, coupled with a lack of exercise is detrimental to so high blood pressure and Diabetes the kidney. There are also ingredients that can burden our kidney directly. This is especially true when the kidney function is already reduced.

Salt, phosphate and protein can compromise the kidneys
The following ingredients you should be aware of:
Salt: Too much salt is charged to the kidneys, you can get the sodium chloride is not completely remove from the blood. As a result, the blood pressure rises. Nutritionists do not recommend more than six grams of salt per day.
Particularly salt rich products are mainly finished, because salt makes the products durable and you are therefore, salt-rich. A couple of Wiener sausages to provide two grams of salt. In addition, some bread contain a lot of hidden salt were 250 grams of bread are seasoned with about four grams of salt.
Phosphate: The mineral is important for bone structure. Too much of it to cleanse the kidneys from the blood. The Phosphate levels are too high, it can overload the filtering organs and lead to vascular calcification.
Phosphate is naturally in many fruits and vegetables contain, however, in small quantities and in a bound Form, which absorbs in the body. Otherwise, the phosphate is, as it is as an additive to many foods. Under the E-numbers 338 to 341, 343, 459 to 325, it serves as a Stabilizer and thickener, and is contained in, for example, Cola, sausages and melted cheese and is absorbed by the body very well.
Protein: proteins are essential nutrients. The main component of our muscles, for example, is protein. “But many of us take too much of it because we often eat meat,” says nephrologist. Who eats more than the of the DGE recommended 0.8 grams per kilogram of body weight daily, is a burden on his kidneys. Excess protein is converted to urea and the kidneys must remove in the urine. An example: a 70 kg body weight you should only eat about 56 grams of protein per day. 100 grams of beef 26 gram protein, 100 grams of yogurt 5 grams.
Overall, acidifies meat diet rich in the body in kidney failure, because the kidneys to filter the acids out of the blood and derive. The higher the acid level rises, the more difficult for the kidneys.
Diet plan for the kidneys – a lot of fruits and vegetables against Acidification
Foods that contain very much protein, salt are rich and those with the additive of phosphate, should therefore be limited only to the table. As a rule of thumb, the expert recommends to eat only once a week meat.
“In principle, the Mediterranean diet is also in terms of the health of the kidneys as the ideal diet,” says the Professor. Little meat, high-quality olive oil, some fish and lots of fruits, vegetables and fiber are ideal for kidney function. “Vegetables and fruit to buffer the blood, so Acidification”, explains Clemens Cohen. Especially important:
- Cook for yourself, because you know, what’s really in there.
- On Fast Food, ready meals and Convenience foods are best avoided, because many of the products contain too much salt, sugar and fat, in this way, Obesity and the risk for Diabetes and high blood pressure increase which may, in turn, the kidneys.
Right drink for the kidneys
An important aspect for healthy kidney, the fluid intake is, however. The kidneys must be adequately “flushed”, so that you can derive pollutants reliable. To be enough “one and a half to two liters per day to drink for a healthy renal function completely, more for the kidney is nothing”, clarifies the expert, “unless you, for example, kidney stones.” Then, it is important to flush Out to help with a lot of liquid.
The best way is to drink water. “Water is by nature the ideal drink for us,” says Clemens Cohen. It has no calories and will not be charged. Who deletes their thirst with Cola, have taken a full meal, he warns. But what about with coffee or alcohol in relation to the health of the kidneys?
“If everything remains in the frame, no Problem.” In the process, the framework means up to three cups of coffee and a glass of alcohol per day. This enjoyment quantities for the kidney so far as is known no negative consequences.
