Glomerular filtration is the process by which the kidneys filter the blood,
excreting waste products and fluids. Glomerular Filtration Rate (GFR) is a
calculation that determines how well the blood is filtered by the kidneys. A GFR
under 60 mL/min/1.73m2 may indicate kidney disease-the lower the number is, the
worse the kidney function. Then how to increase it with dietary therapy?
Firstly, increase the daily intake of water unless you are undergoing
dialysis.
Drink water to replace other drinks like soda. Drink alcoholic beverage
moderately. For a female, the daily amount should be less than one small, and
two small for a male. You can discuss the daily water intake with your doctor,
or consult our online experts. For those who are receiving dialysis, it is
necessary to limit the fluid intake.
Secondly, reduce the sodium intake.
The damaged kidneys fail to expel extra sodium and fluid, so water and sodium
retention, and high blood pressure can be caused. You had better avoid eating
processed, canned and frozen foods. Use fresh meats to replace the cured meats.
Choose spices and herbs instead of table salt. This suggestion is suitable
whether or not you are on dialysis.
Thirdly, limit the intake of fatty and high-calorie food.
High fatty and calorie foods will increase your risk for hypertension and
obesity. In turn, the kidney disease can be aggravated. Limit the consume of
oil, butter, margarine, and salad dressings you use. Pick low-fat dairy
products.
Finally, increase the amount of fruits and vegetables.
Replace products like white bread made of refined grains with grain foods
such as whole-wheat pasta and bread. These foods can help boost your general
health and help you maintain a healthy weight.
The above are some suggestions. Consult a dietitian to determine the best
dietary arrangement for increasing GFR and kidney health.
