If you don’t eat right, kidney disease will come! See if you are affected?

The kidney is an important organ that excretes metabolic products, regulates water, electrolytes and acid-base balance, and maintains a stable internal environment. To protect the health of the kidney, you must develop good eating habits that nourish both the stomach and the kidney. Here are some correct eating habits for you.

0 1 Salt intake should be moderate

Salt is an important substance for maintaining the body's fluid balance and normal neuromuscular function. Excessive salt intake can lead to high blood pressure and increase the risk of cardiovascular disease. The World Health Organization recommends that healthy adults should consume no more than 5 grams of salt per day, and patients with hypertension and diabetes should consume even less. In daily life, not only should we control the amount of salt when cooking, but we should also limit the intake of other high-salt foods, such as the following foods.

(1) Sauces, gravies, soy sauces, fermented bean pastes and commercial gravies, etc.;

(2) Processed meats such as bacon, smoked meat, sausage, ham, etc.;

(3) Soup bases such as dry soup bases, canned soup bases, soup bases, soup base powders, etc.;

(4) Sauce-based foods such as pickles, kimchi, etc.

02Protein intake should be reasonable

Protein is an important component of the human body. It is recommended to consume 50-100 grams of lean meat, poultry or fish per meal, or half a cup of cooked beans. Physically active people, pregnant women or nursing mothers can increase the amount appropriately. Excessive intake of protein will be converted into urea through a series of reactions in the body and eventually excreted by the kidneys. Excessive formation of urea will increase the burden on the kidneys.

If you eat too much protein and don't like to exercise, your body will take in too much energy, eventually leading to overweight and obesity. Studies have confirmed that obesity is an independent risk factor for kidney disease. Long-term high-protein diets can also disrupt lipid metabolism in the body, increase oxidative stress in the body, damage vascular endothelial cells, etc., and promote or aggravate kidney disease.

It is worth noting that protein is not limited to eggs and milk. Various meats, seafood and beans all contain more protein. When using these foods, do not accelerate kidney damage just to satisfy your appetite.

03****Control sugar intake

Sugar is an important energy source for the body and plays an irreplaceable role in maintaining normal physiological functions and promoting growth and development. However, it can only provide energy for the human body and cannot provide all the nutrients contained in other foods. If the intake of sugar exceeds the needs of the human body, it will be converted into fat. In severe cases, symptoms related to metabolic syndrome such as vascular endothelial damage, fat metabolism disorders, and obesity may occur, thereby greatly increasing the risk of cardiovascular disease and kidney disease. In particular, diabetic patients should strictly limit their sugar intake.

04Avoid high-fat diet

Long-term high-fat diet will lead to metabolic disorders, overweight or obesity, and metabolic syndrome-related diseases will follow. Studies have found that with the increase of blood lipids, the activity of nitric oxide synthase in the kidney increases, which will produce a large amount of nitric oxide. At the same time, superoxide ions in the kidney also increase. After the two react, they will produce peroxynitrite that is toxic to kidney cells, thereby causing cell apoptosis, leading to glomerular sclerosis and renal interstitial fibrosis. In daily life, you need to be careful when eating crackers, baked goods, bread, French fries, fried fish, onion rings, margarine, etc.

05Beware of high-purine foods

Purine exists in the body mainly in the form of purine nucleotides, and plays a very important role in energy supply, metabolic regulation and the composition of coenzymes. Its metabolite is uric acid. Under normal circumstances, 2/3 of the uric acid produced in the body is excreted by the kidneys, and 1/3 is excreted from the intestines. Excessive intake of purine or other reasons leading to excessive synthesis or excretion of uric acid can lead to hyperuricemia. When the blood uric acid concentration is too high, uric acid is deposited in the joints, soft tissues, cartilage and kidneys, causing foreign body inflammatory reactions in tissues, forming gouty arthritis, gouty nephropathy, urinary stones, etc.

Therefore, people with hyperuricemia, people with hyperuricemia and a family history of gout, etc. should limit their intake of high-purine foods.

In addition, proper water intake and careful use of medication are effective ways to protect the kidneys. In short, developing good eating habits is one of the important ways to prevent kidney disease.
