Today, a team led by Professor Maciej Banach (Medical University of Lodz, Poland) will present the findings of an analysis into the long-term impact of low-carbohydrate diets on mortality (Abstract P5409). “Using data for almost 25,000 participants from the National Health and Nutrition Examination Survey (NHANES), we found that individuals on the lowest-carbohydrate diet had the highest risk of overall (hazard ratio [HR] 1.32; p<0.001), cardiovascular (HR 1.50; p<0.001), cerebrovascular (HR 1.51;p<0.001) and cancer (HR 1.36; p<0.001) mortality,” says Prof. Banach. The association between low-carbohydrate diets and overall mortality was stronger for non-obese than obese individuals.
Prof. Banach adds, “From a meta-analysis of seven published prospective studies, with data on 447, 506 participants and 39,326 deaths, we also found, and in fact confirm, a positive association between low-carbohydrate diets and overall (relative risk [RR] 1.15; p<0.001, Figure), cardiovascular (RR 1.13; p<0.001) and cancer (RR 1.07; p=0.02) mortality.”
This study adds to the growing body of evidence showing the harmful long-term effects of a low-carbohydrate diet. Further studies are needed to examine the effect of diet duration and clarify other reasons for these associations.
