Some patients with chronic kidney disease (CKD) want to know if they can eat fish or if fish is good for them. Here we will make a detailed introduction to answer this question.
As it is known to us, fish is a kind of most popular food in our daily life. Fish contains many kinds of nutrients, such as high-quality protein, calcium, phosphorus, iron, vitamin B1, etc. The patients with chronic kidney disease have the symptom of loss of protein, so they need add the intake of high-quality protein. Why must it be high-quality protein? Let’s see the followings:
High-quality protein is more prone to producing fewer wastes during decomposing. Patients with CKD have something wrong with their kidney filtration. Their kidneys can’t filter the wastes well. So fewer wastes produced are good for patients with CKD. The protein is composed of amino acid, which is divided into essential amino acid and non-essential amino acid. Essential amino acid means that it can’t be produced by function of human body and can only be taken in from the food. However, for non-essential amino acid, we can not only produce it by our function of human, but also can take it in from the food. So essential amino acid contained by high quality protein is more important for our health.
So eating fish is very good for patients with chronic kidney disease.
But it doesn’t mean the more fish patients with CKD eat, the better it is for them. Because when protein is decomposed in our body, urea nitrogen will be produced and usually, the more protein is decomposed, the more urea nitrogen will be produced. Urea nitrogen is normally excreted through our kidneys, so if we take in too much protein, kidney will be under much burden, which does harm to patients with CKD. Besides, the patients with CKD must have a low phosphorus diet. Eating too much fish can elevate the volume of phosphorus in the body, which has a very bad influence on the kidney.
From the above, we can conclude that patients with chronic kidney disease should eat fish but mustn’t eat too much. The best way is you should consult your doctor about your protein intake. Also, you can send your test report to our nephrologists and get free diet advice.
