Study Confirms Low Carb Diets Do Not Harm Kidneys

Page Changed: Diabetic Kidney Damage


While almost any intake of protein is a problem for people with advanced kidney disease, studies have found repeatedly that for people with normal kidney function or early diabetic changes the low carb diet does not promote kidney damage.

This was confirmed in a study published in 2012 of 307 obese individuals without kidney disease who were put on a low carb diet over a two year period. The study, which was published in a high profile journal intended for kidney specialists, concluded that the low carb diet did not cause noticeably harmful effects to patients' kidney function or their fluid and electrolyte balance compared with a low-fat diet.

In Women High Total Cholesterol Correlates with Fewer Heart Attacks

A large epidemiological study published in 2012, which tracked 52,087 Norwegians for ten years, found that their total cholesterol levels did not predict heart attacks--or any other kind of death--and that for women, the higher their cholesterol, the less likely they were to die of heart attack. Indeed, total cholesterol levels up to about 271 mg/dl appeared to be protective against heart disease.
