DASH Diet – Practical Diet Plan to Prevent Recurrent Kidney Stone Risk

Popularly
known as the DASH diet, the Dietary Approaches to Stop Hypertension (DASH) could be an
effective alternative to the usually recommended low-oxalate diet for reducing
the risk of kidney stone recurrence, reveals research published in the March
issue of the American Journal of Kidney Diseases.

A low-oxalate diet is
often prescribed for prevention and
treatment of kidney
stones. But findings from a small randomized controlled trial
showed that a DASH diet, typically recommended to lower blood pressure, is more
effective as it reduced urinary risk markers for calcium oxalate kidney stone
formation.
A research team led by
Dr. Nazanin Noori MD, PhD from the Shahid Beheshti University of Medical
Sciences in Teheran, Iran, observed the dietary interventions of 41 recurrent
stone formers with hyperauxaluria for eight weeks. Changes in the urinary
calcium oxalate supersaturation and 24 hour urinary composition were assessed
in the trial.
The study involved 57
participants, recurrent stone formers with hyperauxaluria, of which the
intervention group were given a DASH style diet, while the control group
followed a low-oxalate diet. 29 participants were randomly assigned to DASH
group, and 28 participants to the low-oxalate group. Of the 41 participants who
completed the trial, 21 were in the DASH group and 20 in the low-oxalate group.

Findings from the
trial showed a trend for increased oxalate excretion in patients who took the
DASH diet as against those who followed the low-oxalate diet. The researchers
conclude that “the DASH diet might be an effective alternative to the
low-oxalate diet in reducing calcium oxalate supersaturation and should be
studied more.”

The DASH diet plan is high in
nutrients and includes whole grains, fruits and
vegetables, nuts and beans, low fat dairy products, some fish and
poultry. Red meat, sweets and fats are also included, but in small
amounts. The DASH diet meets with the
dietary guidelines of the US National Institutes of Health (NIH) and is widely
recommended to prevent and control hypertension or high blood
pressure. This healthy eating plan follows heart healthy guidelines
to limit cholesterol and saturated fat and can prevent osteoporosis, cancer, stroke,
cancer and diabetes.

Dr. Noori observes, “Most people do not eat single, isolated nutrients such as oxalate, but rather
meals consisting of a variety of foods. So, a practical diet plan for kidney
stone prevention should be based on the cumulative effects of foods and the
impact overall dietary patterns have on risk for stone formation rather than
single nutrients.”
