Diet vigilance for kidney disease patients: can we eat phosphorus free fish if we have kidney disease

　　01

Terrible cholesterol

From the nutritional composition table of scaleless fish in the above section, we can see that scaleless fish does have certain drawbacks for kidney friends.

In addition to potassium and phosphorus issues, its cholesterol content is indeed high, especially in silver fish, eel, etc. For kidney friends with hyperlipidemia and coronary heart disease, they should eat less.

But some scaleless fish, such as herring and salmon, are beneficial for kidney friends with high cholesterol because they are rich in unsaturated fat acids.

　　02

Combined lipid metabolism disorder

Kidney disease patients are prone to complicated lipid metabolism disorder, which is manifested as hyperglyceryl triacetaemia, hypercholesterolemia, and mixed hyperlipidemia. Therefore, kidney disease patients should limit their intake of fat and cholesterol, especially those with diabetes nephropathy, nephrotic syndrome, and end-stage kidney disease.

How much do you know about standards

According to the dietary guidelines for Chinese residents, healthy adults with normal blood lipids (also applicable to kidney disease patients with normal blood lipids) generally have a fat limit of less than 0.8 grams per kilogram of body weight per day, and are not allowed to exceed 1 gram per kilogram of body weight per day. The general cholesterol limit is less than or equal to 300 milligrams per day.

Scaleless fish in the eyes of traditional Chinese medicine

According to the traditional Chinese medicine work "Medicinal Property Examination", scaleless fish not only has a high cholesterol content but also belongs to the category of "hair products" in traditional Chinese medicine, so it is not suitable for patients with kidney disease to choose.

"Hair" refers to foods that are rich in nutrients or have irritating properties that are particularly prone to inducing certain diseases (especially old and chronic diseases) or exacerbating existing diseases. For patients with kidney disease, it is not recommended to use it for allergic diseases (such as skin diseases and allergic purple fatigue), which has a certain scientific basis. However, there is no evidence to suggest that it cannot be consumed for non allergic diseases such as kidney disease.

At present, there is no exact scientific basis for modern research in this field.

Suggestions

Although scaleless fish have high levels of cholesterol, potassium, and phosphorus, they also have many benefits, such as rich and high-quality protein, abundant vitamins, and trace elements (calcium, magnesium, selenium, iodine, zinc, etc.).

But we also need to be clear that nothing is absolute, and refraining from eating does not mean keeping your mouth shut: compared to stable kidney disease patients, eating a moderate amount of scaleless fish every week is still a good choice. Being able to effectively diversify the sources of high-quality protein, rather than simply consuming enough high-quality protein from a single food.
