What should patients with kidney disease pay attention to in their diet?

Kidney disease has become more and more common in our lives. It is also becoming more and more common among younger people and is receiving more and more attention in people's lives. So what should kidney disease patients pay attention to in their diet?

1. Sweets must be prohibited (unless blood sugar is low)

First of all, for patients with high blood sugar, sweets must be prohibited, such as white sugar, brown sugar, rock sugar, glucose, maltose, honey, chocolate, toffee, fruit candy, candied fruit, etc.

2. If blood sugar is not well controlled, it is best not to eat fruit

If you can control it well, you can eat small amounts of low-sugar fruits such as apples, pears, tangerines, oranges, grapefruits, etc.

3. Pickled products must be prohibited

Pickled foods contain many carcinogens. Eating too much of them will not only cause cancer, but also cause great damage to the kidneys. Pickled foods contain a lot of chemicals, which are very harmful to the body. If you are a patient with kidney disease, it is best to eat more light foods, which is also very beneficial for your kidneys.

4. Do not eat the following foods

Spinach, bamboo shoots, leeks, fennel, celery, radishes, etc. as well as soy products, animal offal, thick chicken soup, broth, etc. Fried foods are prohibited.

5. Do not eat irritating foods

Such as wine, tea, coffee, various spicy condiments, such as onion, ginger, garlic, curry, mustard, pepper, etc., various spices.

6. Limit salt intake

Edema and blood volume are closely related to salt. Every gram of salt can carry about 110 ml of water. If patients with nephritis consume too much salt, the urination function will be damaged. Edema will often be aggravated, blood volume will increase, and heart failure will occur. Therefore, salt intake must be restricted and a low-salt diet must be given.

7. Eat less salt

If there is no edema or hypertension, the daily salt intake is about 4g. If there is edema and hypertension, the daily salt intake is 2-3g due to a low-salt diet, or less than 0.5g on a salt-free diet. Avoid high-salt foods such as pickles, salted eggs, cured meat, pickled vegetables, preserved eggs, fermented tofu, etc. It is not advisable to eat bananas because they contain a lot of sodium salt, and patients with nephritis who suffer from edema and high blood pressure must limit their sodium salt intake.

8. Limit protein

The amount of protein intake should be determined according to the renal function. If the patient has oliguria, edema, hypertension and nitrogen retention, the daily protein amount should be reduced to 20-40 grams/day (appropriate endogenous metabolic nitrogen) to reduce the burden on the kidneys and prevent the accumulation of non-protein nitrogen in the body. However, this low-protein diet cannot be consumed for a long time, and can only be used for 7 to 10 days at most. Because long-term use of a diet with low nutritional value is not only detrimental to the stimulation and inhibition process of the cerebral cortex. It also affects endocrine metabolism and the consumption of inherent protein in the body. If the blood urea is normal and the creatinine clearance rate is close to normal, the daily protein supply should reach 1 gram/kg body weight.
