Ha K, et al. - Based on the data from the Korean Genome and Epidemiology Study, researchers studied the link between dietary fat and carbohydrate consumption with incidence of type 2 diabetes mellitus (T2D). For this investigation, they involved 5,595 adults (aged 40–69 years) without diabetes, cardiovascular diseases or any cancer at baseline. By the validated semi-quantitative food frequency questionnaire, dietary intake was quantified. According to results, 1,010 cases of T2D were newly determined during a median follow-up of 138-months. Very-low-fat or very-high-carbohydrate consumption might raise the risk of T2D and may be related to lower intake of different nutrients and unbalanced macronutrient composition.
