About 30 percent of people with type 1 diabetes and 10 percent to 40 percent of those with type 2 diabetes eventually develop nephropathy, or diabetes-caused kidney failure, according to the National Kidney Foundation. Although existing kidney damage cannot be reversed, future kidney damage in diabetics can be stopped or slowed by following a specific, specialized diet aimed at conserving existing kidney function.
1. Limit Protein, Salt, Potassium & Phosphorous
o Diabetics suffering from kidney failure should eat a diet low in protein, sodium, potassium, phosphorus and dairy. LifeClinic.com says men should limit their protein consumption to 5 to 6 ounces a day and women to 3 to 4 ounces a day. A low-protein diet appears to reduce protein in the urine and increase protein in the blood, which helps diabetics with kidney failure preserve their existing kidney function.
Sodium and potassium intake should also be limited. Herbs and spices can be used as a substitute for salt, but sodium substitutes that use potassium should be avoided. In terms of fruit, kiwis, nectarines, cantaloupe, prunes, raisins, bananas and oranges should be completely avoided because of their high potassium content. Fruits such as apples, grapes, peaches, plums, tangerines and pineapples can be eaten in moderation. Potatoes, spinach, asparagus, pumpkin, squash and tomato should also be avoided because of their high potassium content. All other vegetables can be eaten in moderation.
Diabetics suffering from kidney failure should also avoid foods high in phosphorus. These include chocolate, nuts and beer, among others. Dairy should be limited to half a cup a day because of its high phosphorus and protein content. Cheese, in particular, should be avoided or eaten in very small, infrequent servings. For the most part, whole grains can be eaten freely, as long as blood sugar levels are controlled.
Kidney problems in diabetics are further complicated because sugar intake must be kept low in order to regulate blood sugar levels. Because of the many food limitations and restrictions on diabetics suffering from kidney problems, it can be difficult for these people to consume enough calories to meet their nutritional needs. Calories should be added through starches and vegetables rather than proteins, dairy and high-sugar fruits. It is extremely important for diabetics with kidney failure to drink enough water, although exact water and liquid intake should be determined by the patient's doctor.
How strictly a diabetic patient must adhere to the above diet depends on the stage of kidney failure. Diabetics in the early stages may be able to consume higher levels of protein and potassium than those at the end stages. A nutritionist or nephrologist (kidney specialist) should be able to determine the patient's stage and dietary needs.
If you are diabetic, then you know how important it is to stay on the proper diabetic diet. Diabetes can affect the kidneys, so often a good diabetic diet will include foods healthful for renal functioning. Diabetic and renal diet guidelines are promoted to encourage people suffering from diabetes or kidney failure to do everything they can to eat in the most healthful way possible for their conditions.
1. Low Sugar
o Sugar should be eliminated as much as possible. Any packaged foods should be chosen based on their low-sugar content.
o Salt can tax the kidneys and raise the blood pressure. Avoid adding salt to food and try to buy foods that are lower in sodium.
o Protein can also tax the kidneys. Try to avoid eating high protein foods or limit your protein intake to 8 ounces per day.
o Potassium is regulated in the kidneys, so try to avoid eating foods high in otassium, such as bananas.
o Dairy products can aggravate blood sugars and strain the kidneys, so try to limit the amount of dairy products you include in the diet.
An Indian meal of naan, potatoes and a mango lassi to drink may be delicious and classic Indian fare, but it's not appropriate for a diabetic diet . Fortunately, you can enjoy the spicy flavors of Indian cuisine without paying for it with a high blood sugar reading later. Consider adding these Indian foods to your healthy diabetic diet.
Tandoori is a fibre-rich, whole-grain bread that's more diabetic-friendly than refined Indian breads like chapati and dosa. Because whole-wheat bread is digested and absorbed more slowly than white bread, it reduces the risk of dangerous blood sugar spikes. Additionally, regularly consuming whole grain can boost your cells' sensitivity to insulin, according to the November 2003 "American Journal of Clinical Nutrition." More insulin-sensitive cells can help make managing your blood sugar easier.
Channa masala is a flavorful chickpea-based South Indian classic bursting with dietary fiber. Karen Collins of the American Institute for Cancer Research states that beans like chickpeas contain ample amounts of soluble fiber. Soluble fiber delays digestion of carbs, helping you achieve even blood sugar levels. Additionally, the soluble fiber in chickpeas can help decrease elevated cholesterol levels.
Bland vegetables transform into mouth-watering superfoods when prepared as Indian vegetable curry. Containing a variety of nutrient-dense veggies like eggplant, spinach and carrots, vegetable curry is an excellent source of low glycemic index vegetables. The glycemic index is a measurement of how rapidly the carbs in a food end up as blood sugar. Including low glycemic index carbs in your diabetic diet can help you keep your blood sugar levels in check, the Glycemic Index Foundation reports.
Bhindi is a flavor-packed Indian side dish containing the vegetable okra. In addition to being a fibrous, low glycemic vegetable, okra contains compounds that can reduce the risk of diabetic kidney damage, the November 2010 edition of the "Jilin Medical Journal" states. In the study, 72 diabetic volunteers were given a diabetic diet or the same diet containing daily okra. The okra group had healthier kidneys at the end of the six-month followup period compared to those who didn't eat okra.
