quickly eat with lots of salt ( fried chicken, fried potatoes, instant noodles)
The sodium content in fast food is often very high. When consuming too much sodium, the kidneys have to work continuously to excrete it, gradually leading to high blood pressure, a direct cause of impaired kidney function.
WHO recommends limiting sodium to less than 2g/day (equivalent to 5g of salt) to protect the kidneys and cardiovascular system.
A portion of fried chicken with French fries contains up to 2.5-3g of sodium, nearly half of the daily requirement.
Red meat and animal organs
Beef, Lamb, liver, animal kidneys provide a lot of animal protein and purines. Eating regularly causes the kidneys to filter many metabolic products such as Ureas and uric acid, leading to an increased risk of impaired renal insufficiency.
A diet rich in animal protein increases the risk of reducing excretion of the kidney gland (eGFR) in middle-aged people by 25%.
People at risk of kidney failure should reduce red meat to less than 2 meals/week, instead with fish or plant fillets.
Processed foods rich in hidden phosphorus (chics, jambon, processed cheese)
Many packaged foods use phosphat-containing additives to create color and enhance flavor. High levels of phosphorus cause calcium-phosphorus imbalances, leading to calcium-nephritis metabolism and dysfunction of filter function.
The International Nephrological Organization (ISN, 2024) recommends prioritizing fresh foods, limiting sausages, jambons, industrial cheese to reduce the metabolic burden on the kidneys.
Sweet foods, sugary soft drinks
Carb soft drinks and cakes contain a lot of refined sugar, increasing the risk of obesity and type 2 diabetes, the leading causes of kidney disease.
People who drink a can of soft drink/day or more have an 18% higher risk of Niederlycemia ( early signs of kidney damage) than those who do not drink it.
According to the WHO, limiting free sugar intake to less than 25g/day significantly reduces the risk of kidney disease and heart disease.
Prioritize fresh, home-processed foods to control salt, sugar and additives.
Replace red meat with fish, beans, nuts rich in lean protein and low in purines.
Reduce the frequency of fast food, no more than once a month.
Increase green vegetables, fruits with less sugar and drink enough water to help the kidneys filter for toxins.
