Around 10% of the world's population suffers from kidney disease. The kidney is a small, bean-shaped organ and performs several vital functions of the body, including the filtering of waste materials, the production of hormones that control blood pressure, ensure the fluid balance of the body, etc.
The main causes of kidney disease are diabetes and high blood pressure , Overweight, smoking, genetic reasons, age, etc. are also factors that affect the health of the kidneys. High blood sugar levels and blood pressure damage the blood vessels in the kidneys. If the kidneys are not functioning properly, waste from food and other sources will accumulate in the blood. This requires that people suffering from kidney disease follow a special diet.
The diet can be varied according to the severity of the disease. Patients who have reached the advanced stage must follow a "kidney-friendly diet", which should reduce the mixing of waste with blood. It is also referred to as a "renal diet" and prevents further kidney damage and improves its function.
People with a diseased kidney should avoid or reduce the intake of food containing sodium, potassium, phosphorus and protein. Appropriate modifications to the diet must be made on the recommendation of a physician.

»Cauliflower: A nutrient-rich vegetable, cauliflower contains plenty of vitamins C, K and folates such as vitamin B. It also has anti-inflammatory compounds such as indole and fiber.  »Red Grapes: It contains plenty of vitamin C and antioxidants like flavonoids that control inflammation and control diabetes.
