A low-GI diet preserves renal function (eGFR) better than a whole-grain wheat-fiber diet in patients with type 2 diabetes over 3 years.

If you have type 2 diabetes, a low-GI diet may offer better protection for your kidneys than a standard high-wheat-fiber diet. While both diets are healthy, the low-GI approach helped maintain kidney function (eGFR) better than the wheat-fiber diet, which showed a slight decline in kidney function over 3 years.

GoodSupportsHIGH confidence
The low-GI diet resulted in preservation of renal function, as estimated glomerular filtration rate, compared with the reduction following the wheat-fiber diet.
