2013-08-13 10:00

A Dietary Treatment for ADPKDAs an inherited disease, ADPKD is not uncommon to appear in families. Since the abnormal genes determine the onset of ADPKD, no specific treatment can treatment it radically. However, a dietary treatment, along with proper medical treatment, can help control this disease largely and slow down its progression. How to make a dietary treatment for ADPKD?

1. Follow a low-protein diet

Our liver is responsible for breaking down protein, and then kidney filters out the waste products. If excess protein is taken in, it will increase the burden on kidney largely. To reduce the workload on kidney, a low-protein diet is quite necessary.

Soy contains rich protein that is believed to be excellent for keeping this disease under control, but fermented soy should be avoided.

2. Keep the intake of salt low

High blood pressure always occurs as the first symptom of ADPKD. In some cases, patients also have swelling. Salty foods can worsen not only patients’ hypertension but also swelling. From this point, canned foods, processed foods, salty cheese, chips, etc, should be got rid of.

3. Take more vitamin B3

In ADPKD, there is one special type of protein, call SIRT1, which affects the formation and growth of kidney cyst. According to recent clinical researches, vitamin B3 has an effect on inhibiting the activities of SIRT1, so as to slow the progress of ADPKD. Thereby, these patients had better increase the intake of foods high in vitamin B3 moderately.

4. Have more Omega-3 fatty acids

This form of fatty acids has a great potential in reducing the possibility of PKD renal cyst from onset, because of its anti-hypertensive and anti-inflammatory benefits. Some fishes, linseed oil, walnuts, etc, are rich sources of Omega-3 fatty acids. Try to find out which one is suitable for you with doctors’ help.

Although the basic dietary requirements for people with ADPKD are similar, the detailed suggestions should depend on their individual conditions. For example, fish can provide Omega-3 fatty acids for ADPKD patients, but some of them contains high phosphorus that is harmful for some patients. Therefore, only if you choose the correct type and amount of foods can dietary treatment control your condition effectively. (If any confusion, welcome to leave a message or send email to
