1. Kidney diseases

Formulation of kidney diseases is general and includes any disease, disorder or condition of the kidneys. Kidneys are vital organs located in the upper internal abdomen. Normally, people have two kidneys, which are part of the component of the urinary tract of the genitourinary system.

Renal diseases are caused by multiple conditions that cause damage to the kidneys and their function. In a person diagnosed with kidney disease, kidney performs its function with difficulty or is unable to function, critical situation for both life and general health condition.

2. Renal failure

In case that does not work normally, the kidney may have difficulties in:
- Filtering waste products and excess water and salts in the blood, which are then eliminated from the body through the ureters, bladder and urethra as urine;
- Production of certain hormones such as renin, which helps regulate blood pressure;
- Production of the active form of vitamin D
- Balancing electrolytes and other vital substances such as sodium, calcium and potassium;
- Adjust the quantity and quality of fluid in the body;
- Stimulating the production of red blood cells.

There are two general types of severe kidney disease:

- Acute renal failure – a condition characterized by deterioration of renal function that starts suddenly and may be caused by conditions such as trauma, acute pyelonephritis, urinary tract obstruction or ingestion of certain toxic substances.

- Chronic renal diseases are those in which deterioration of renal function persists for a long period of time, over the years or months.

Researchers have found links between several chronic diseases, inflammation and certain types of foods which can prevent or contribute to protection against unwanted oxidation of fatty acids – action that triggers the reaction between oxygen and fats and cells in the body.

Oxidation is a normal process in energy production and is found in many of the chemical reactions in the body, but excessive oxidation of fats and cholesterol gives rise to molecules known as free radicals. They can damage the proteins, membranes and genes. Heart disease, cancer, Alzheimer’s, Parkinson’s and many other chronic and degenerative diseases are related to oxidative processes.

However, foods that contain antioxidants can help neutralize free radicals and protect the body. Many of the foods that protect against oxidation are included in diets for maintaining healthy kidneys and are excellent choices for patients suffering from chronic kidney disease or are on dialysis.

A proper diet is recommended especially for people diagnosed with kidney disease because they have a higher risk of developing cardiovascular disease.

3. Vegetables

1. Red pepper – 1/2 cup red pepper contains one mg of sodium, 88 mg of potassium, 10 mg of phosphorus.

Onions are rich in flavonoids (especially quercetin – a powerful antioxidant that helps reduce the risk of heart disease and protect against many types of cancer). Onions is low in potassium and is an adequate source of chromium, a mineral that helps metabolize carbohydrates, fats and proteins. Onion can found and used in different varieties, from white to the red onion.

4. Fruits

1. Apples – 1 medium apple with peel contains 0 mg sodium, 158 mg potassium, 10 mg phosphorus. Apples are known for their role to reduce cholesterol, prevent constipation, protect against cardiovascular disease, reducing the risk of cancer. Apple is rich in fiber and anti-inflammatory compounds.

2. Cranberries – 1/2 cup cranberry juice contains 3 mg sodium, 22 mg potassium, 2 mg phosphorus, 1/4 cup cranberry sauce contains 35 mg sodium, 17 mg potassium, 6 mg phosphorus; 1/2 cup dried cranberry contains 2 mg sodium, 24 mg potassium, 5 mg phosphorus.

These sour-tasting berries are known to protect against bladder infection by preventing adhesion of bacteria to the bladder wall. Similarly, cranberries prevent the development of gastric ulcers and protect the gastrointestinal lining which supports healthy gastrointestinal system. It has been shown that cranberries prevent cancer and heart disease.

3. Blueberries – 1/2 cup of fresh blueberries contains 4 mg sodium, 65 mg potassium, 7 mg phosphorus. Blueberries are rich in antioxidant phytonutrients, which gives them the blue color. These fruits contain multiple natural compounds that reduce inflammation.

Blueberries are a good source of vitamin C, manganese (which maintains healthy bones) and fiber. These fruits help protect the brain from some of the effects of aging. It turned out that the antioxidants in blueberries and other berries prevent slow bone destruction due to low estrogen levels.

Blueberries can be eaten fresh or dried and can be stored frozen for several months. Are delicious mixed with cereal, cream, muffins and other desserts.

4. Raspberry – 1/2 cup of raspberries contains 0 mg sodium, 93 mg potassium, 7 mg phosphorus. Raspberries contain a phytonutrient called ellagic acid that helps neutralize free radicals to prevent cell damage.

They contain flavonoids, antioxidants that gives the red color and are an excellent source of vitamin C, fiber and folate. Raspberries inhibit cancer cell growth and tumor formation. Raspberries can be eaten with cereal, smoothies, desserts or as sauces and juice, but also fresh.

5. Strawberries – 1/2 cup fresh strawberries containing 1 mg sodium, 120 mg potassium, 13 mg phosphorus. Strawberries are rich in two types of phenols: anthocyanins and ellagitannins. Anthocyanins are those due to which strawberries are red, being powerful antioxidants that protect cell structures in the body and prevent oxidative damage.

Strawberries are an excellent source of vitamin C and manganese, and contain much fiber. They are known for their role in protecting the heart, but also for their role in anti-cancer and anti-inflammatory fight. Strawberries can be combined with cereals, smoothies, cream or can be eaten fresh.
