Consumption of high-fat dairy associated with lower diabetes risk
People who consume the most high-fat dairy products, about eight or more portions per day, have a 23-percent lower risk of developing type 2 diabetes than people who have one serving or less, according to recent research published in Diabetologia.
The study aimed to examine which types of dietary fat were associated with diabetes prevention, as many previous studies have found that replacing saturated fat with monounsaturated and polyunsaturated fat can help ward off type 2 diabetes.
Nearly 27,000 people between the ages of 45 and 74 were recruited for the study, which included 14 years of follow up. The researchers adjusted for age, sex, BMI, physical activity, smoking and alcohol consumption, among other factors.
Increasing high-fat dairy food consumption, like cream and milk, was associated with a significant reduction in diabetes risk, but there was no association between intake of low-fat dairy products and lowered type 2 diabetes risk.
"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]," Dr. lrika Ericson, study author, said in a press release.
Researchers also found that increased consumption of meat, regardless of fat content, was associated with increased type 2 diabetes risk. However, the highest risk was associated with lower-fat meats.
"Our findings suggest, that in contrast to animal fats in general, fats specific to dairy products may have a role in prevention of type 2 diabetes," Dr. Ericson said.
