It’s wonderful to learn that there can be further good effects to healthy eating. So, the latest announcement from the National Kidney Foundation was most welcome.
“A diet high in fruits, vegetables, legumes and nuts, moderate in low-fat dairy products, and low in animal proteins, refined grains and sweets may reduce risk for developing kidney stones, according to a new study published in the March issue of the National Kidney Foundation’s American Journal of Kidney Diseases. March is National Kidney Month and the National Kidney Foundation encourages people to learn about the kidneys and associated conditions, including kidney stones.
“Researchers found that compared with following a low-oxalate diet – the frequently prescribed diet for kidney stone prevention and treatment – a Dietary Approaches to Stop Hypertension (DASH)-style diet may be more effective at reducing urinary risk markers for calcium oxalate kidney stone formation, the most common type of kidney stone. Oxalate is naturally found in high levels in many foods with other nutritional value including: beets, navy beans, bulgur, kale, almonds, sweet potatoes, rice bran, rhubarb and spinach.
“According to the National Kidney Foundation, most kidney stones are formed when oxalate binds to calcium while urine is produced by the kidneys. Eating and drinking calcium and oxalate-rich foods together during a meal may be a better approach than limiting oxalate entirely. This is because oxalate and calcium are more likely to bind to one another in the stomach and intestines before the kidneys begin processing, making it less likely that kidney stones will form.
“Previous studies have recommended that those with kidney stones follow a low-oxalate diet to reduce one’s chances of forming another stone. However, many high oxalate foods are healthful and a low-oxalate diet can be very restrictive. The DASH diet reflects a more balanced diet and as a result may be easier and more realistic to follow long-term,” said Dr. Kerry Willis, Senior Vice President for Scientific Activities at the National Kidney Foundation.”
