Ha K, et al. – In this study, researchers analyzed the association of dietary fat and carbohydrate intake with the incidence of type 2 diabetes mellitus (T2D). The study sample consisted of 5,595 Korean adults (aged 40-69 years) without diabetes, cardiovascular diseases, or cancer at baseline. Using a validated semi-quantitative food frequency questionnaire, the researchers measured dietary intake. They identified 1,010 patients with T2D during a median follow-up of 138 months. According to findings, a very-low fat or very-high carbohydrate intake may increase the risk of T2D and may be linked to a lower intake of different nutrients and an unbalanced macronutrient composition.
