Koolhydraatarm dieet en de nieren?*
Uit een kleine studie onder 307 mensen met overgewicht blijkt dat het volgen van een
koolhydraatarm en eiwitrijk dieet niet schadelijk lijkt voor de nieren. De deelnemers in de studie waren van het begin af vrij van problemen met hun nieren. Verdere studie is nodig om te kijken of deze bevindingen ook gelden voor mensen met al bepaalde aandoeningen zoals bijv. diabetes en hoge
bloeddruk.
Are The Kidneys Damaged By Low-Carb Diets?
Low-carbohydrate, high-protein diets - like the Atkins diet - have been popular among dieters for years. For just as long, experts have worried that such diets might be harmful to the kidneys. A study appearing in an upcoming issue of the Clinical Journal of the American Society of Nephrology (CJASN) looks into these safety concerns.
Allon Friedman, MD, (Indiana University School of Medicine) and his colleagues compared the effects of a low-carbohydrate, high-protein diet versus a standard low-fat diet on a variety of kidney-related measures in 307 obese individuals without kidney disease over a two year
period.
The researchers found that a low-carbohydrate high-protein weight loss diet did not cause noticeably harmful effects to patients' kidney function or their fluid and electrolyte balance compared with a low-fat diet. "These results are relevant to the millions of healthy obese adults who use dieting as a weight loss strategy," said
Dr. Friedman.
The authors noted that further follow-up is needed to determine even longer-term effects of the diet on the kidneys. Additional studies should also evaluate the effects of the diet in different types of individuals, such as those with chronic kidney disease, diabetes, or hypertension, and those at increased risk of developing kidney stones.
