And that is where you come across the DASH diet - the ultimate answer for your troubles with kidney health .
On this World Kidney Day (14 March), get to know more about the DASH diet, that could be your saviour - shielding your kidneys from ailments.What Is The DASH Diet?
Among the plethora of diet plans introduced, the DASH diet is one of the most effective diet plans . Designed for combating blood pressure and reducing the risk of heart disease, the diet is beneficial currently considering the rampant hike in the number of individuals suffering from heart disease, kidney failure and stroke .
Dietary Approaches to Stop Hypertension or DASH diet was developed with the intention of preventing or treat hypertension (high blood pressure) and to reduce the risk of heart diseases in individuals who suffer from hypertension. The diet focuses on the incorporation of vegetables, fruits, whole grains and lean meat into one's daily diet .
As per the researchers' understanding, people who followed diets rich in vegetables (plant-based diets), such as vegans and vegetarians had a low risk of developing high blood pressure. This was considered while developing the diet, which can be witnessed in the diet's emphasis on fruits and vegetables as well as lean protein sources like chicken, fish and beans. DASH diet does not advise the intake of red meat, added sugars, fat and salt. The low consumption of salt, promoted by the DASH diet is beneficial for people with high blood pressure , .
Apart from reducing blood pressure, the DASH diet is asserted to have a positive impact in weight loss, decreasing cancer risk, lowering metabolic syndrome risk, reducing the risk of diabetes as well as heart disease risks. In the current article, we will view the applicability of the DASH diet for better kidney health and the ways through which it can impact individuals suffering from kidney diseases .Impact Of DASH Diet On Kidney Health
Recommended by the National Kidney Foundation and approved by The National Heart, Lung and Blood Institute, The American Heart Association, the Dietary Guidelines for Americans - the DASH diet is asserted to have a positive impact on your kidney health. The diet is a recognised treatment for kidney diseases, as it can effectively slow down the progression of kidney diseases. DASH diet helps in reducing your blood pressure, which subsequently helps in improving your kidney health and restricting the onset of many diseases .
Rich in potassium and calcium, and containing a moderate amount of sodium, the DASH diet is optimal for your kidneys. A study conducted on exploring the relation between DASH diet and kidney health revealed that as the diet is high in fruits and vegetables, moderate in low-fat dairy products, and low in animal protein helps in kidney stone prevention .
Consuming plenty (controlled and balanced) of vegetables and fruits can aid by preventing the formation of kidney stones. The study pointed out that, the increased consumption of these increases urinary citrate (an inhibitor of calcium stone formation). Also, it has a normal to high calcium content but low animal protein and sodium level, thereby decreasing the risk of calcium oxalate stone recurrence .
Individuals who consume nuts and legumes were reported to have lower risks of developing chronic kidney diseases. The DASH diet has very low dietary acid load than typical diets, which is linked with reduced risk of kidney diseases. It does not cause any inflammation as well. Likewise, the diet has been proven to reduce the levels of uric acid (a substance linked to increased CKD risk). Studies have revealed that urate-lowering therapies are beneficial for improving kidney function which supports the claim that uric acid can be responsible for kidney diseases. The diet can significantly lower the uric acid levels, especially among adults suffering from hyperuricemia .
In a study conducted by the American Journal of Kidney Diseases, it was asserted that following the DASH diet can help in reducing the risks of developing kidney ailments . However, the study states that it is increasingly beneficial in the case of individuals with normal weight and not obese . The research results pointed out that the participants who ate few fruits, vegetables and nuts, and consumed more red meat and sodium had a 16 per cent (more) chances of developing kidney diseases in comparison to the ones with high DASH scores; that is, individuals who ate more vegetables, nuts, fruits etc., and less of the unhealthy items such as sugar, meat etc.
DASH diet is beneficial for kidney health because of its ability to reduce blood pressure, as hypertension has been linked to kidney disease. And as aforementioned, the other reason for the positive impact is asserted to be due to the dietary acid load in the foods people eat, or the overall acidity of the foods in a DASH diet . High acid foods include meats and cheeses and low acid foods include fruits and vegetables.
Consequently, the proteins from the lean meat may pose risks to your kidney but is overshadowed by the proteins from vegetables and fruits. In comparison to the number of vegetables and fruits to be consumed as per the DASH diet, the amount of meat and meat products are remarkably low. This can be attributed to the understanding that the possibility of damage caused by meat can be overcome by that of the vegetables and fruits . One thing most of the studies held in common was that it is always better to incorporate healthy eating habits before the onset of the diseases than after.
If you are already suffering from chronic kidney disease, consult your doctor and your dietician before starting the DASH diet .
Important note: The DASH diet should not be used by people on dialysis, as individuals on dialysis have special dietary needs that should be discussed with a registered dietitian .DASH Diet For Kidney Health
