Turns out, higher levels of biomarkers of dairy fat consumption are associated with a lower risk of developing type 2 diabetes, a new study has revealed.

International nutritional guidelines commonly recommend regular consumption of dairy products as an important source of key nutrients, and in high-income countries, eating low-fat dairy products is encouraged as part of overall recommendations to limit saturated fat consumption. In some researches, consumption of dairy products, in particular, yogurt and cheese, has been associated with a lower incidence of type 2 diabetes.

Biomarkers are tell-tale molecules in the body that can be measured accurately and consistently, and act as indicators of dietary consumption.

Concentrations in body tissue of certain types of fat have been found to correlate with consumption of fat-rich dairy foods, both in self-reported studies and in intervention studies where participants eat a controlled diet. These biomarkers of dairy fat offer a complementary approach, alongside self-reporting of food consumption, to investigate associations of dairy fat consumption with type 2 diabetes in large populations.

The researchers examined specific biomarkers of dairy fat consumption from a total of 63,682 adults from 16 multi-national studies. These participants were all free from type 2 diabetes when the first samples were taken, and 15,158 of them went on to develop type 2 diabetes over the follow-up period of up to 20 years. In each of the studies, the researchers analyzed the relationships of dairy fat biomarkers with the risk of developing type 2 diabetes.

When all the results of the 16 studies were pooled the researchers found that higher concentrations of dairy-fat biomarkers were associated with lower risk of developing type 2 diabetes. This lower risk was independent of other major risk factors for type 2 diabetes including age, sex, race/ethnicity, socioeconomic status, physical activity, and obesity.

For example, if people among the top fifth of the concentrations of dairy-fat markers were compared with people among the bottom fifth of the concentrations, the top-fifth people had an approximately 30 percent lower risk of type 2 diabetes.

“Our results provide the most comprehensive global evidence to date about dairy fat biomarkers and their relationship with lower risk of type 2 diabetes. We’re aware that our biomarker work has limitations and requires further research on underlying mechanisms, but at the very least, the available evidence about dairy fat does not indicate any increased risk for the development of type 2 diabetes,” said lead study author, Fumiaki Imamura.

“We hope that our findings and existing evidence about dairy fat will help inform future dietary recommendations for the prevention of lifestyle-related diseases,” added Fumiaki.

Despite the several advantages of evaluating fatty acid biomarkers, the researchers caution that the results cannot distinguish between different types of dairy foods (e.g., milk, cheese, yogurt, others), which could have differential effects. (ANI)
