Diet for Kidney Disease | Functions and Sources

How does the nutrient affect the body?

Normally, kidneys filter many substances from the blood. These substances include the following:

by-products of chemical reactions in the body

salt

waste products from the foods we eat

water

Eventually these substances are passed out of the body in the urine. When the kidneys are damaged, they cannot filter the blood. Substances can build up to harmful levels. This buildup can damage other organs of the body and cause numerous problems. Certain substances are restricted in the diet to prevent this toxic buildup.
