What the kidneys do
The kidneys work through more than 150 quarts of blood each day to separate out the body’s waste. Small units inside the kidneys, called nephrons, host a chemical exchange where waste and excess water exit the blood and are taken by the urinary system.

What harms the kidneys
Foods rich in animal protein are not suggested if you have kidney problems. A diet high in protein can aggravate these conditions. Avoid eating chicken, turkey, eggs, meat, and other animal protein sources. Metabolizing the proteins causes the kidneys to enlarge and adds stress to other organs.

Uric acid is a toxic substance that accumulates within the body. The harmful substance can cause damage to the kidneys as well as other organs.  Blending and drinking a cup of cranberries with water and lemon juice cleanses the kidneys of uric acid.

Kidneys worst aggressors:
Animal protein
Genetically Modified Foods
Artificial sweeteners
Carbonated drinks
Dairy products

What protects the kidneys
Lots of potassium and magnesium, plenty of water, fresh fruits, vegetables, and herbs.

1/2 avocado
1/2 peeled lime or lemon
1 peeled kiwi
1/4 cup of walnuts (optional)
1 banana
1 node of fresh cilantro
1 cup of distilled water

Tip: You may also add a handful of spinach or kale, or two ounces of wheat grass to your smoothie.

Remember! It is important to eat foods that are organic to avoid the intake of toxins, fertilizers, dirt, and pesticides.  Any non-porous produce that is not available in organic form can be cleaned thoroughly with a fruit/veggie wash. Porous produce must be organic.  Kiwi for instance, has a very thin membrane; therefore it absorbs the pesticides deep into its flesh.  Other whole foods heavily sprayed with pesticides include peppers, celery, apples, cherries, cucumbers, grapes, lettuce, peaches, spinach, tomatoes, and berries.
