There is a saying in English "man is what he eats", which means that the food a person eats has a great impact on his mind and health. So, how does food affect our kidneys?
Schematic／
Salt is needed by the human body, but if ingested too much, once it exceeds the amount that can be excreted by the kidneys, it will cause fluid retention and increase blood pressure. It is easy to cause lesions, and the blood vessels of the whole body become fragile and inflexible for a long time; because the kidneys are rich in blood vessels, they are naturally affected. High-salt foods, including frozen foods, canned foods, biscuits, etc., should be reduced. However, for some elderly people with degraded sense of smell and taste, it is not appropriate to emphasize lightness, which leads to decreased appetite for eating and uneven nutrition, and needs to be adjusted according to individual circumstances.
Commercially processed foods (such as sausages, bacon, jerky, etc.) are often added with too much phosphate in order to preserve, add color and flavor, and these inorganic phosphates are almost 100% absorbed in the intestinal tract. When kidney function is poor, phosphorus excretion is reduced, and too much phosphorus in the body can affect bone and increase abnormal calcification of soft tissues (such as heart, blood vessels). Studies have shown that even in people with normal kidney function, excessive intake of phosphorus can have adverse effects on the kidneys and bones.
Diets with high sugar content, such as sugar-sweetened beverages, if ingested too much, it is easy to cause poor blood sugar control in diabetic patients, and long-term high blood sugar will increase the bodyInternal oxidative stress causes abnormal secretion of cytokines, and over time, the structure of the glomerulus changes (fibrosis), resulting in the loss of protein (proteinuria), the decline in glomerular filtration rate, and the development of diabetic nephropathy.
In addition, fructose is usually added to sugar-sweetened beverages, and fructose can be said to be "non-drunk alcohol", which is easy to cause metabolic syndrome and may lead to addiction. Fructose that cannot be completely consumed will eventually become fat accumulation, and the concentration of uric acid will increase during the metabolic process, increasing the chance of gout. This is not a good thing for normal people, and it is even more threatening to kidney patients.
With so many foods that are bad for the kidneys, isn't there any food that is good for the kidneys? In fact, there is, and that is "healthy eating" - meta-analysis shows that for the general population, people who eat a healthy diet have a lower incidence of chronic kidney disease and a lower incidence of proteinuria. And among people with kidney disease, those who followed a healthy diet had a lower mortality rate.
Risk factors for chronic kidney disease include diabetes, hypertension, cardiovascular disease, obesity, etc. Previous studies have shown that a healthy diet has positive effects on blood sugar, blood pressure, cardiovascular disease, and body weight. It may be that a healthy diet improves these risk factors and further protects the kidneys.
Patients often ask that the easiest way to protect the kidneys is to start with diet. If you have no special chronic diseases, it is recommended to have a balanced diet, mainly natural foods, more fruits and vegetables, and less salt, less oil, and less sugar. Try to use fish or white meat instead of red meat. The most important thing isStart early.
