It seems like every day there is some new research about foods that are helpful for Chronic Kidney Disease (CKD) patients. Still, those with chronic diseases should be aware of these foods that researchers have deemed best to help you live longer. Kidney has tailored the list of foods to match the diet of those with CKD.
A kidney diet takes into consideration the right amount of protein and calories so as not to overwork the kidneys. Essential nutrients such as calcium, phosphorus, sodium, potassium and other vitamins and minerals must also be regulated. As the body tends to retain fluid when kidneys malfunction, regulation of fluid intake also comprises a kidney diet.
PROTEIN
Protein helps build muscles, repair tissues and fight off infections. However, increase in protein intake may result to increase amounts of urea in the body. Urea is a body waste mainly excreted in the kidneys. Increase amounts of urea means the kidneys will have to work double to rid the body of the waste.
CALORIES
Persons with chronic kidney conditions need to maintain their ideal weight. It is therefore, essential that calorie intake must be monitored at all times. Since protein is a major source of calorie, a kidney diet substitute calorie source from protein with simple carbohydrates. Good sources of calories include low-cholesterol fats such as canola and olive oil. Simple carbohydrates are foods rich in sugar such as honey, syrup, jelly and jams.
CALCIUM and PHOSPHORUS
Phosphorus must be regulated because it has tendency to increase. When this happens, a person experiences skin itching and decrease in calcium levels. It may cause bone weakness and may predispose a person to develop osteoporosis. Calcium, on the other hand, must also be regulated because excess amounts may cause kidney stone formation. Foods rich in calcium are often rich in phosphorus too.
POTASSIUM
Potassium levels tend to increase when your kidneys do not function normally. This mineral plays an important role in keeping the heart beating steadily. If potassium levels become abnormally high, it may cause cardiac arrhythmia. Potassium is mostly present in certain fruits vegetables.
SODIUM (Salt)
A low-salt diet is recommended to avoid fluid retention in the body. Salt can make you thirsty and can increase blood pressure due to excessive amounts of fluid in the body. A chronic kidney diet recommends that you eat foods with lower than 100 mg of sodium per serving. Always read the labels and avoid foods with salt listed at the top of the ingredients.
FLUIDS
Reduction in fluid intake is not an essential part of a kidney disease diet. It is only recommended in the late stages of the disease. Fluid may result to emergency condition such as shortness of breath. If your doctor advised you to reduce your fluid intake, you must avoid foods with high water content. Watermelons, melons, tomatoes, celery and lettuce contain high amounts of water. Eating ice cream, Popsicles and soups as well as drinking other beverages also count in your fluid intake.
IRON
A kidney disease diet must be high in iron intake especially in the advanced stages of the disease. Should there be a need for you to increase your iron level, include more liver, chicken, beans, pork and iron-fortified cereals in your diet.
