Translations:Low-carbohydrate diet/21/en

The proportion of carbohydrate in a diet is not linked to the risk of type 2 diabetes, although there is some evidence that diets containing certain high-carbohydrate items – such as sugar-sweetened drinks or white rice – are associated with an increased risk. Some evidence indicates that consuming fewer carbohydrate foods may reduce biomarkers of type 2 diabetes.

A 2019 consensus report on nutrition therapy for adults with diabetes and prediabetes the American Diabetes Association (ADA) states "Reducing overall carbohydrate intake for individuals with diabetes has demonstrated the most evidence for improving glycemia (blood sugar) and may be applied in a variety of eating patterns that meet individual needs and preferences." However, another source states that there is no good evidence that low-carbohydrate diets are better than a conventional healthy diet in which carbohydrates typically account for more than 40% of calories consumed. Low-carbohydrate dieting has no effect on the kidney function of people who have type 2 diabetes.
