HealthDay News — Sources of dietary fat may influence risk of developing type 2 diabetes, according to research presented at the European Association for the Study of Diabetes in Vienna, Austria.
“Dietary fats could affect glucose metabolism and insulin sensitivity and may thereby have a crucial role in the development of type 2 diabetes,” noted Ulrika Ericson, PhD, of the Lund University Diabetes Center in Malmö, Sweden, and colleagues.
To assess the association between the intake of dietary fat and incident type 2 diabetes, the investigators analyzed data for 26,930 patients (60% female), aged 45 to 74 who had been followed for more than 14 years.
Incidence of type 2 diabetes was lower (hazard ratio, 0.77; 95% CI: 0.68-0.87; P<0.001) for those in the highest quintile for intake of high-fat dairy products (median, eight portions per day) compared with the lowest quintile (median, one portion per day), found the investigators.
High intake of meat and meat products was associated with increased risk of incident type 2 diabetes for both high-fat meat (HR, 1.09; 95% CI, 0.97-1.24; P<0.001) and low-fat meat (HR, 1.25; 95% CI: 1.11-1.41; P< 0.001).
“The decreased risk at high intakes of high-fat dairy products, but not of low-fat dairy products, indicate that dairy fat, at least partly, explains observed protective associations between dairy intake and type 2 diabetes,” concluded the researchers.
