As an internist, I always encounter patients asking these questions: Doctor, I heard that these are not allowed to be eaten? If you have kidney disease, you can’t eat rooster, carp, goose, beef and mutton, mushrooms and other foods because they are hairy? If you have kidney disease, you can’t eat soy products? If you have kidney disease, onion, ginger, garlic, chili, etc. are irritating foods that cannot be eaten? ……. In the face of such incessant questions, we internal medicine doctors often answer to the point of being overwhelmed! In fact, the above “avoid eating” methods widely circulated among patients are all wrong! They are not based on any scientific evidence. If we let these dietary principles without any scientific basis to occupy the “headline” position in the hearts of patients for a long time, it will not only not help patients’ condition, but also make some people suffer from malnutrition and lose their confidence in recovering from the disease due to the wrong diet, thus aggravating their condition. Therefore, our kidney on line according to the results of professional nephrology nutrition collated a kidney disease diet overview to help you initially understand: with kidney disease, in the end how to eat scientifically! First, all healthy food, there is no kind of limit, only care about the amount of collocation Our body needs a variety of nutrients, these nutrients from different healthy food, these types of food, for patients, there is no good or bad, it is about the amount of “collocation”! And people think that hairy food can not be eaten, has violated this one dietary principle! Each place on the hairy things say different, the more widely circulated is beef and mutton, chicken, duck and goose, fish, shrimp and crab, and some say also include cilantro, scallions, ginger, garlic, milk, eggs, peaches, plums and so on, if all together, basically covers all the kinds of food we often eat, hairy things do not eat, basically nothing to eat! Hair belongs to the Chinese characteristics, there is no international hair this said, so there is no valid evidence that kidney disease patients can not eat hair! There is no basis to say that hair will affect the condition! Second, different stages of kidney function, master different principles of collocation According to the patient’s kidney function, we divided the kidney disease into five stages, chronic kidney disease 1 ~ 5 stages, in different stages, the diet with different. 1, kidney function 1-2 stage: low salt, high quality protein diet; 2, kidney function 3-4 stage, and 5 stage has not yet dialysis: low salt, high quality low protein diet; 3, kidney function 5 stage of dialysis patients: low salt, high quality adequate protein diet. If the patient has elevated blood phosphorus, blood potassium and uric acid, then on top of the above, correspondingly add low phosphorus, low potassium and low purine diet. Third, how to implement these scientific dietary principles? After distinguishing their own kidney function stage, we start to right! 1, low salt: there have been many international research results that the intake of too much salt will increase the burden on the kidneys and cardiovascular, and the World Health Organization is calling on ordinary people to maintain a low-salt diet. The human body only needs 2g of salt a day to maintain the basic needs. Therefore, the average person requires less than 6g of salt a day, and kidney disease patients require about 3g of salt a day (6g of salt is about a beer bottle cap of salt spread, 3g is half of it). When you really implement low salt, you know how hard it is to do! If you still do not let put onion, ginger, garlic, cilantro, chili pepper and other seasoning, food tasteless, simply rice do not want to eat, so if you have a little gastrointestinal stimulation of these condiments do not have adverse reactions, then there is no problem to add fresh ingredients such as onion, ginger and garlic seasoning when making dishes. 2, high quality and low protein: This is one of the most difficult aspects of kidney disease nutrition. High-quality protein includes: meat, eggs, milk, soy protein (soy protein is also commonly known as soy products, such as tofu); non-quality protein includes: staple foods, vegetables, fruits, etc. Kidney function 1-2 stage, the total amount of protein can be relaxed moderately as ordinary people, not high protein diet can be. For stage 3-4 kidney function, and stage 5 patients who have not yet been dialysed, in order to delay the decline of kidney function as much as possible, the total protein requirement should be much lower than that of ordinary people, and not too much high-protein food should be consumed, while ensuring that high-quality protein is in the majority. Like meat, eggs and milk, which are rich in protein, must be eaten in moderation and not excessively. Meat is usually 1-2 taels a day, milk 250ml can be eaten, eggs only 1, and replace 1-2 meals of ordinary staple foods with wheat starch, which contains almost no protein, to reduce the protein intake of staple foods. How should I understand a high quality low protein diet? 1, high uric acid (low purine diet): very easy to cause high uric acid food are animal offal, wine, especially beer, drinks, seafood, thick broth, these avoid eating; pork, beef and mutton and other meat can be eaten, but moderate to reduce some; eat more fruits and vegetables. 2, high blood potassium (low potassium diet): most Chinese medicine contains high potassium. Among staple foods: potatoes are high in potassium, and most of the potassium in potatoes can be removed by cutting and soaking them in water; among fruits: bananas and apricots, which are high in potassium; among vegetables: spinach, lotus root, scallions, fresh mushrooms, yams are high in potassium, while dried yam (shiitake mushrooms, fungus) and seafood (kelp, nori) are very high in potassium. 3, high blood phosphorus (low phosphorus diet): animal offal; whole grains such as cereals, rice, brown rice, barley; dairy products such as fresh milk, cheese; vegetables mainly shiitake mushrooms, enoki mushrooms, straw mushrooms, etc.; other foods including a variety of processed foods, chocolate, coffee, milk tea, ice cream, fish roe, nuts.
