Supplement 2: Details of subjects and methods

Dietary assessment

Habitual diet was assessed using a validated semi-quantitative self-administered 125-item food frequency questionnaire (FFQ) with a reference period of one month (1;2). Participants indicated the frequency of intake of foods within main food groups (times per day, per week, per month, or never) combined with questions on the intake of specific foods within the main food groups (seldom/never, sometimes, often, mostly/always). Specific questions were dedicated to different types of edible fats used for meal preparation and as spread on bread. Dietary intakes of total energy (MJ/day), total fatty acids, SFA, MUFA, PUFA, TFA, protein, carbohydrates, dietary fibre, alcohol (En%), and cholesterol (mg/day) were calculated from the 2011 version of the Dutch food composition table (3). Intakes of fatty acids from major dietary sources were estimated by summing the intakes from specific foods that were categorized into dairy, meat, and plant food groups (see Supplemental Table 1 for a detailed list of dietary sources). Coffee and sugar-sweetened beverage intake (g/day) was estimated by summing the intakes of relevant foods in the FFQ.

Laboratory methods and calculations

Fasting plasma glucose concentrations were determined by enzymatic and colorimetric methods (Roche Modular Analytics P800, Roche Diagnostics, Mannheim, Germany; CV < 5%) and serum insulin concentrations were determined by an immunometric method (Siemens Immulite 2500, Siemens Healthcare Diagnostics, Breda, The Netherlands; CV < 5%). HbA1c concentrations were measured by HPLC boronate affinity chromatography (Primus Ultra, Siemens Healthcare Diagnostics, Breda, The Netherlands; CV < 3%). All analyses were performed in the central clinical chemistry laboratory of the LUMC (4). From measured glucose and insulin concentrations, we calculated Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) and HOMA of beta-cell function (HOMA-B) as markers of hepatic insulin resistance and steady-state insulin secretion (5). HOMA-IR was calculated as fasting insulin (μU/ml) * fasting glucose (mmol/l) / 22.5 and HOMA-%B as 20 * fasting insulin (μU/ml) / fasting glucose (mmol/l) − 3.5 (5;6). In addition, we calculated the total area under the curve for overall glucose (glucoseAUC) and insulin (insulinAUC) concentrations by the trapezoidal rule as (15 * fasting concentration + 75 * concentration30min + 60 * concentration150min) / 150. The Disposition Index a marker of whole-body beta-cell function that accounts for variations in whole-body insulin sensitivity, was calculated as Insulinogenic Index * Matsuda Insulin Sensitivity Index (7). Insulinogenic Index was calculated as total insulinAUC / total glucoseAUC and Matsuda Insulin Sensitivity Index as 10,000/square root [fasting glucose (mg/dl) * fasting insulin (μU/ml)] * [meanglucose0-150 * meaninsulin0-150] (7-9).

Statistical analysis

All results presented in this paper are based on weighted analyses to represent a population-based study with normal BMI distribution. In this cohort persons with a BMI of 27 kg/m2or higher are oversampled. To correctly represent associations in the general population, data of the participants were weighted towards the BMI distribution of participants from the Leiderdorp municipality (10;11), whose BMI distribution is comparable to the BMI distribution of the general Dutch population (12).

Underreporting of dietary energy intake may be specific to certain macronutrients, in particular total fat, among obese individuals (13;14). Therefore potential energy under-reporters were identified on the basis of disparities between reported energy intakes and predicted energy requirements, using the ratio of Goldberg’s cut-off point for energy intake (EI) to basal metabolic rate (BMR) ratio (10;15). We assumed a within-subject variation in energy intake of 23%, a within-subject variation in estimated BMR of 8.5%, and a between-subject variation in physical activity level (PAL) of 15% (15). BMR was estimated by an equation for obese and sedentary individuals (16), and the PAL was estimated to be 1.55, the average PAL of a middle-aged, moderately active population (15). Participants with reported energy intake under the cut-off point (EI:BMR < 1.09) were considered energy under-reporters.

For interpretation of the results, regression coefficients were back transformed and expressed as percentage with 95% confidence intervals (CI). For an equal interpretation of regression coefficients below 0 as those above 0, we back transformed the regression coefficients towards percentages increase as: (exp(beta) - 1)*100 if beta > 0 and percentages decrease as: - (exp(-beta) - 1)*100 if beta < 0.

2Linear regression coefficients of the ln-transformed markers of type 2 diabetes risk were back transformed and expressed as percentage with 95% CI. Individual data were weighted to BMI distribution of the general Dutch population.

3Linear regression models (carbohydrate substitution model) were adjusted for age (years), sex (M/F), total energy intake (kJ/day), alcohol (En%), dietary fibre (En%), total body fat (%), smoking (never/former/current smoker), education level (low/middle/high), physical activity (MET hours/week), family history of diabetes (no/yes), statin use (no/yes), energy under-reporter (no/yes), coffee (g/day), sugar-sweetened beverages (g/day), dietary cholesterol (mg/day), protein (En%),all other fatty acids (En%).

4After stratification for dietary source, the multivariate regression models were additionally adjusted for the intake of fatty acids from the other dietary sources.
