Drinking milk at breakfast can help people with type 2 diabetes to control the disease, according to a study published yesterday in the Journal of Dairy Science.
A group of scientists from the University of Guelph (Canada) measured the effects of breakfast 250 ml of milk on the levels of glycemia and the feeling of satiety of 32 healthy adults.
The results showed that consumption reduced the value of postpandrial glycemia (blood glucose two to four hours after eating) of all participants during the day. Moreover, the effect was enhanced in those who consumed enriched milk with proteins. The finding could be crucial if it is taken into account that maintaining blood sugar levels is essential for patients with type 2 diabetes.
The study also showed that milk promoted the feeling of fullness, so that the studied population would eat less during lunch and therefore reduce their risk of obesity, another important factor for the appearance and management of diabetes, type 2
With the increase of this disease in the world, as one of the greatest concerns of human health, these results are of great importance, said Professor Douglas Goff of the University of Guelph, who directs the work.
According to Goff and his colleagues, proteins that are naturally present in milk, such as casena, release gstricas hormones that slow down digestion, increasing the feeling of fullness.
It is also known that proteins in general reduce the absorption of carbohydrates, explains Anbal Donoso, nutrilogo and diabetologist at the University of the Andes Clinic.
"This can probably explain the drop in blood glucose levels," says the doctor.
"It is an important finding, bearing in mind that we have an obese population in Chile and that milk is a much cheaper product than others of protein intake."
Vernica Cornejo, head of the Laboratory for Genetics and Metabolic Diseases at INTA, believes that if these changes in blood glucose occur, local studies are needed to measure the benefits of milk consumption in the Chilean population with diabetics.
