How to eat less protein
Understand why you might need to eat less protein.
If you have problems with your liver or your kidneys, for example if you have been diagnosed with chronic kidney disease you may be told to lower your protein intake. When your body processes food, the wast product urea is formed.
If you have problems with your kidneys the urea may not be passed as it should. A build-up of such waste products can be very damaging for your health.
