For the renal and diabetic patient diets plays important role.
In diabetes body cannot use glucose and therefore glucose stays in the blood causing high blood glucose level. This high glucose level causes many serious conditions like kidney disease, heart problems, eye damage etc. Renal diabetes is kidney disease which arises due to low-sugar threshold in the kidneys.
Kidneys are the filtering system of our body. The main function of kidneys is cleaning blood by separating wastes and toxins from the blood. When blood glucose level remains high for a long time, it damages tiny blood vessels of the kidneys. The kidneys then can’t work properly and it gets damaged. In this situation kidneys cannot clean the blood properly and hence, the waste materials build up in our blood.
Diabetes also damages nerves of the body, resulting into difficulty of emptying the bladder. If urine remains for a long time in our bladder, an infection develops due to the growth of bacteria in urine. All these problems are the result of high glucose levels in the blood.
Diet is an effective solution for diabetes and kidney disease. Glucose is the form of sugar which we get from food. If we able to manage food intake (by a proper diet plan), it helps to control blood glucose level. Diet for renal diabetes means intake of right amount of daily calories that include right amount of protein, fat, and carbohydrates. It also means that we limit or lower the amounts of potassium, sodium and phosphorus in our diet. Your dietitian can help you plan an ideal diet. He/she will first study the nature of your renal diabetes and then instruct you about how much protein, carbohydrates, sodium, potassium, phosphorus and fat you can have each day.
Proteins are helpful in muscle diseases. We get proteins mostly from meat, milk, eggs, beans, and nuts. Damaged kidneys fail to separate the protein from the wastes. So, doctors advice to limit the amount of protein. However, we cannot avoid protein entirely.
Sodium in the food raises blood pressure, that’s why renal patients should limit foods that contain high levels of sodium. Salt, canned foods, or processed foods (frozen dinners) are sodium rich foods. Many fruits and vegetables contain potassium. Renal diabetic patients have to include balanced amount of potassium in their diet because a diseased kidney fails to remove excess potassium and high potassium level can affect the heart.
High cholesterol level also results in kidney failure. High-fat food is a source of cholesterol. If we include fatty foods in our daily meal, it results in the increase of cholesterol levels inside the walls of blood vessels and can cause heart attacks and strokes.
A renal diabetic diet is based on potassium, phosphorus, sodium and sugar content of foods. In this diet many healthy plant foods need to be limited. The choice of foods depends upon nutrition requirements, stage of kidney disease, and type of diabetes. To plan perfect diets always take the help of your dietitian. A Dietitian plans diets according to individual nutritional needs. You can have lots of variety in your diet with the help of food lists recommended by doctor or a registered dietitian.
