What is prescription food?

Prescription food is food that is formulated by a veterinarian or animal nutritionist based on the pet's disease or nutritional status to help restore health. Just as humans have introduced dietary management to relieve discomfort and enhance the efficacy of medicine, animal medicine now also includes the role of diet in treatment plans. The prescription food that came into being is not simply a mixture of medicine and food, but a combination of treatment and food, with different food designed for different conditions. Achieve the purpose of dietary therapy with precise nutritional ratio.

In order to improve this problem, you need to drink a lot of water and excrete the accumulated metabolites from the body through urine.

Limit protein content. Many toxic products accumulated in the blood are the result of protein decomposition. Reducing protein intake can effectively alleviate the occurrence of this situation and improve the quality of life. However, the protein should be limited in moderation. If it is too little, it will be detrimental to the health of your pet.

Low phosphate content. Restricting the phosphate content in the diet can reduce blood phosphorus concentration and reduce the possibility of secondary hyperparathyroidism, which is more beneficial to the alleviation of renal failure.

Adding antioxidants can prevent further damage to the kidneys; fatty acids can help maintain smooth blood flow in the kidneys and reduce inflammation.

Kidney prescription food is formulated taking into account the above factors, and mixing it will obviously break the original meaning of the prescription food and make it lose the expected effect. Therefore, mixed food is used as a transitional function at the beginning, and then it will gradually improve after feeding the prescribed food alone.

Why choose prescription food?

Helping medicines work: Many times after doctors prescribe medicines to sick dogs, the food in normal dog food may interact with certain substances in the medicines, affecting the effectiveness of the medicines. Prescription food is designed according to different pathologies and can promote the efficacy of medicine through food.

Reduce the burden on the body caused by illness: For example, if your dog suffers from liver disease, taking prescription dog food for liver disease can reduce the burden on the liver by reducing the substances that the liver needs to metabolize, and help the liver recuperate.

Reduce the dosage of medication: If the dog suffers from a disease that requires a large amount of medication, it can be adjusted through food to control the delay of the disease. The doctor can reduce the dosage of medication. For example, for dogs with diabetes, if the dog can be well controlled If you eat more food, the doctor may reduce the dosage of insulin, which can reduce the side effects after taking the medicine.

Control or slow down the recurrence of the disease: Like human diseases, many dog ​​diseases are easy to relapse after being cured, such as urinary stones. Many dogs with urinary stones relapse soon after surgery. The design of urinary stone prescription food is based on the principle of urinary stones, reducing the elements that cause crystallization and increasing the inducing elements that make dogs drink as much water as possible. Improving this kind of prescription food can naturally effectively reduce the chance of recurrence or prolong the time of recurrence.

Some misunderstandings about prescription food

Prescription food itself does not contain pharmaceutical ingredients, whether it is Western medicine or traditional Chinese medicine. No additions are allowed, and the mainstream international prescription foods are designed by adjusting the levels of various nutrients. This technical threshold is very high. For example, in prescription foods for heart disease, the sodium ion content should generally be controlled at about 0.2%. Because all ingredients in the raw materials contain sodium ions, sodium must be removed through a process, which requires very high technical requirements. In addition, it is also a misunderstanding to use traditional Chinese medicine formula to regulate food. The nutritional content of food is not processed, and conditioning by traditional Chinese medicine alone should not be included in the food category.

For example, some chronic diseases, such as kidney failure, heart disease, and food allergies, require lifelong food intake, and dietary changes are not allowed throughout life.

Prescription foods cannot be used to prevent certain diseases and cannot be consumed as medicine.

Do not mix and match with staple food

As you can imagine, prescription food is a targeted food used to restore health. Prescription food first has the word prescription. As the name implies, it must be prescribed by a person with the right to prescribe before it can be used. This means that a professional veterinarian must decide whether or which prescription food the sick cat or dog should eat. If pet owners purchase and use it by themselves, it can easily cause danger to their pets. For example, if a cat suffers from heart disease and kidney disease at the same time, the veterinarian will decide which prescription food to eat based on the specific situation and disease characteristics.

Relatively speaking, of course, no staple food is as nutritious as it is. The editor recommends that if you find that your pet has health problems, you should not change their food easily. The first choice is to go to the hospital for a check-up. If a disease problem is found and needs to be treated with prescription food, it is recommended not to mix it with the staple food. The purpose of prescription food is to better help some dogs with special health, such as obesity, kidney disease and other sick dogs, to improve their diet in stages. Except that you can mix prescription food with ordinary food during the transition period, do not mix food again in the future.
