Following a diet much like the Dietary Approaches to Stop Hypertension (DASH) eating strategy—which is full of fruits, vegetables, and lowfat dairy product—may stave off chronic kidney disease (CKD), based on 2 new studies.
At one more visit and baseline, participants self-reported their consumption of processed and red meat, low fat dairy product, sodium, fruits, vegetables, whole grains, nuts, legumes, and sweet beverages in a validated 66-item food frequency survey. None were given dietary guidance.
Dr Rebholz and co-workers corrected for recognized CKD risk factors including comorbid illnesses (e.g., diabetes and hypertension), systolic blood pressure, antihypertensive drugs, baseline kidney function, sociodemographic variables, as well as lifestyle variables (e.g., smoking, calorie consumption, overweight, and physical action). Significantly, they were not able to evaluate albuminuria.
High consumption of red and processed meats (e.g., cold cuts) was correlated with a 22% greater risk of CKD. Conversely, low fat dairy product, and regular consumption of nuts and legumes were linked with hazards that were 16% and 9% lower, respectively. Results didn't change.
Several potential mechanisms may lead to decrease in CKD danger, co-workers and Rebholz described. In addition, it has a lower dietary acid weight than typical American diets, and previous studies have linked kidney disease and acid weight. Typical American diets, unlike DASHBOARD, may spur inflammation and endothelial dysfunction, ultimately causing both kidney and cardiovascular disorders.
Additional results suggested that protein from meat raises threats whereas proteins from dairy product and vegetable may be protective.
Uric acid can be lowered by dASH
In another study, published in Rheumatology & Arthritis, researchers found a DASH-style diet can lower uric acid, a substance linked to increased CKD danger.
“Our study demonstrates the DASH diet can lower uric acid levels, especially among adults with hyperuricemia.”
Co-workers and Dr Juraschek performed an ancillary study of the DASH-sodium trial, a randomized control trial that initially analyzed the sway of a DASH diet and changing quantities of sodium. Participants have meals in a crossover design at low, moderate, and high sodium levels of 60, 120, and 180 mmol of sodium daily for 30 days each.
While the study didn't directly measure kidney function, the researchers reported the DASH diet efficiently lowered serum uric acid by 1.3 mg/dL in adults with raised uric acid above 7 mg/dL. The effect size was comparable to that attained with drugs. Grownups with diabetes, advanced kidney disease, or cardiovascular disease were excluded from your study as mentioned at pain forum.
The researchers also found that higher amounts of sodium, reflective of an average American diet, reduced serum uric acid, particularly in people that have high blood pressure. The mechanism is not clear, but may entail decrease in urate and sodium reabsorption. The findings don't support using up excessive or typical quantities of sodium the researchers stressed. Instead, clinicians should take note that serious changes in uric acid can happen.
The study confirms the DASH diet to lower uric acid ” Dr Juraschek said at health message boards
