A research study carried out in Canada has found that a high-protein milk when consumed with cereal at breakfast, helps reduce blood sugars.
The study was carried out recently by a team from the Human Nutraceutical Research Unit of the University of Guelp in conjunction with the University of Toronto in Canada on the effects of milk on blood sugar levels. The team found that drinking a high-protein milk with cereal at breakfast time can help lower a diabetics blood sugar levels. The study was conducted in a bid to see the benefits of a changed breakfast routine on Type-2 diabetes management.
It found that high-protein milk when consumed at breakfast, helps reduce the postprandial blood glucose concentration, compared to milk with standard protein levels. The study also found that using high-protein milk also helped reduce a person’s appetite after a second meal of the day, compared to when using low-protein equivalents.
"Metabolic diseases are on the rise globally, with Type-2 diabetes and obesity as leading concerns in human health," said Douglas Goff, from the team of the University of Guelph.
"Thus, there is impetus to develop dietary strategies for the risk reduction and management of obesity and diabetes to empower consumers to improve their personal health," he continued.
The Study -
To conduct the study, the research team examined the effects of increasing protein levels, and the quantity of whey protein in milk consumed with a high-carb cereal breakfast, on blood glucose levels.
They also examined the effects of these changes on a person’s food consumption later in the day and feelings of fullness. They found that the digestion of proteins in milk releases gastric hormones, that lead to slow digestion and a ‘full’ feeling. They also found that the digestion of whey proteins achieves this ‘full’ feeling quicker and makes this feeling last longer.
Only a small difference was noticed in lunch meal consumption levels after increasing whey protein at breakfast, though researchers did find that milk consumed as part of a high-carb breakfast helped reduce blood glucose levels after lunch.
"This study confirms the importance of milk at breakfast time to aid in the slower digestion of carbohydrate and to help maintain lower blood sugar levels.” said Prof. Douglas Goff
“Nutritionists have always stressed the importance of a healthy breakfast, and this study should encourage consumers to include milk." He concluded.
